I am looking at making a table view section that extends another section like the image. Although this is purely aesthetic if you know of an easy way of doing this I would like to know.
You different section can have different background image and different frames for the subviews.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"myCell"];
if(cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"LOC_ID"];
[cell autorelease];
}
if(indexPath.section == 0){
if(indexPath.section == 0 && [self tableView:numberOfRowsInSection:0]-1 == indexPath.section){
//put background image for last row in section 0
} else {
//backgroundimaes for all other cells in section0
} else if(indexPath.section == 1) {
//configure section 1 ibackgroundimages
}
}
return cell;
}
setting background of an cell
cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_bg.png" ]autorelease];
cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_selected_bg.png"];
Nice diagram. If you are trying to create a UITableView with sections that have different widths, that is not possible. You will have to use two separate UITableViews with different widths, and put one below the other. Or just set up some UITableViewCells manually and don't use a UITableView at all.

Im working on Multiple checkbox Functionality in tableview, I have to search in google finally i got it one solution.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
if ([selectedRowsArray containsObject:[contentArray objectAtIndex:indexPath.row]]) {
cell.imageView.image = [UIImage imageNamed:#"checked.png"];
}
else {
cell.imageView.image = [UIImage imageNamed:#"unchecked.png"];
}
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleChecking:)];
[cell.imageView addGestureRecognizer:tap];
cell.imageView.userInteractionEnabled = YES; //added based on #John 's comment
//[tap release];
cell.textLabel.text = [contentArray objectAtIndex:indexPath.row];
return cell;
}
- (void) handleChecking:(UITapGestureRecognizer *)tapRecognizer {
CGPoint tapLocation = [tapRecognizer locationInView:self.tableView];
NSIndexPath *tappedIndexPath = [self.tableView indexPathForRowAtPoint:tapLocation];
if ([selectedRowsArray containsObject:[contentArray objectAtIndex:tappedIndexPath.row]]) {
[selectedRowsArray removeObject:[contentArray objectAtIndex:tappedIndexPath.row]];
}
else {
[selectedRowsArray addObject:[contentArray objectAtIndex:tappedIndexPath.row]];
}
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:tappedIndexPath] withRowAnimation: UITableViewRowAnimationFade];
}
In that code i have one doubt. what is selectedRowsArray and what is ContentArray Please explain anyone. Thanks in advance.
The selectedRowsArray is another array maintained beside your contentArray which is used to hold the content for of the cells that are currently selected in the UITableView. The contentArray holds the actual content which is populated the cells.
Make note of the following lines:
if ([selectedRowsArray containsObject:[contentArray objectAtIndex:indexPath.row]])
{
cell.imageView.image = [UIImage imageNamed:#"checked.png"];
}
else
{
cell.imageView.image = [UIImage imageNamed:#"unchecked.png"];
}
The cell contents are checked for their presence in the selectedRowsArray which means that the cell is selected.
The selection and deselection is handled by the handleChecking: method which adds or removes the object from the same index in the contentArray into the selectedRowsArray.
You must have understood by now that cells in a UITableView are reused, so the actual number of UITableViewCells in the memory are most probably less than the number of cells to be shown in the UITableView. Hence the need for a system which can actually determine whether the cell is currently selected so this status can be populated when the cell is rendered again in the view.
Alternative methods to achieve the same involve using Booleans in an array representing the status of each cell, or simply the indexes of each selected cell in an array.
I am trying to use Storyboards on this project. I cntrl drag from a static tableview cell to a new viewcontroller select push.
When I run the app and click the tableviewcell, which I dragged from in the previous step, nothing happens?
I am not sure if I have screwed things up by also putting in my tableviewcontroller class the following method.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = #"Cell1";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1];
}
[cell.textLabel setFont:[UIFont fontWithName:#"GothamRounded-Light" size:18]];
cell.textLabel.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
[cell.detailTextLabel setFont:[UIFont fontWithName:#"GothamRounded-Light" size:12]];
cell.contentView.backgroundColor = [UIColor statOffWhite];
if (indexPath.row == 0) {
cell.textLabel.text = #"Profile";
}
else if (indexPath.row == 1) {
cell.textLabel.text = #"Support";
}
else if (indexPath.row == 2) {
cell.textLabel.text = #"Share";
}
else if (indexPath.row == 3) {
cell.textLabel.text = #"About";
}
else if (indexPath.row == 4){
cell.textLabel.text = #"";
cell.frame = CGRectMake(0, 0, self.view.bounds.size.width, 200);
UIImageView *watermark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"watermark.png"]];
watermark.frame = CGRectMake((cell.frame.size.width/2) - (watermark.image.size.width/2), 80, watermark.image.size.width, watermark.image.size.height );
[cell addSubview:watermark];
}
return cell;
}
// UPDATE ////////
I took out the cellForRowAt method and the storyboard thing worked. But since I have taken out that method how can I set my font on my cell to be a custom font that isn't in Xcode's selections? I have included the font in my project, which I use everywhere.
What happen with your implementation of cellForRowAtIndexPath: is that your are creating cells from scratch and overwriting the storyboard's cells (hence your segue not being triggered).
If you defined static cells in your storyboard, you should not dequeue and create cells yourself. If your class is a subclass of UITableViewCellController, you could call the implementation of super and use the returned cell.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
// Customize your cell here
}
Note however that doing so makes little sense : all the things you are doing in your cellForRowAtIndexPath: method could and should for simplicity sake be done in the storyboard.
If you really need to customize a static cell programmatically, the way to go is to define an outlet to this cell in your view controller and customize the cell in the appropriate method (viewDidLoad for example).
I am making a form within a grouped tableview. In this form I have UIswitches and textfields. But after scrolling down, the cells styles are changing.

After some searching I found that more people are having this problem. And that the problem lays in this piece of code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
static NSString *MyIdentifier = #"GenericCell";
cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
}
NSString *text = nil;
But I don't find a solution for it.
Hope anybody can help!
Kind regards!
Clarification
Oké so here you see a screenshot of my form. below I have a red cell (save button) when I scroll down other cells are getting a red background. And some cells, text property's are changing.
That is not gong to work. Aparently you did not yet fully understand how the re-use mechanism works.
What do you do?
First you fetch a cell to be re-used. If you get one -fine so far but the problem comes later. If you don't get one then you create a new one.
When you have created a new one, which is the case at start before the user begins scrolling, then you add some UIItems depending on section and row. I will explain why this is not actually a smart thing to do.
Then the user scrolls. Cells will dissappear from screen and then made available for re-use. Then you will fetch the cells for re-use. But it may well happen that those cells already have additional UI-Items on them because you have used them before in that way. In the following process you will add new UI Items regardless whether there are already additional UI-Items on that very cell.
What can you do:
Create your own custom table cell subclasses. One subclass for each set of additional ui items that you may need. That is probably the neatest way of doing it. For each subclass use a different re-use identifier (!!!)
This is what I would recommend!
However, there are alternatives:
You could still live with your concept but invent an individual type of re-use identfier for each type of cell that has some type of additional ui item on it. If so, then make sure that these UI items are only created and added as sub-views in the if (cell == nil) branch of your code. Only create them once and then re-use them. Cell reuse-IDs could be "email-display", "email-input" , "password-display", "password-input", "switch", ...
A variance of the solution above would be, to calculate row and section
into the reuse-identifier. Such as "cell-id-0.2" for section 0 and
row 2 - or so. But still you will have to make sure that you really
re-use the additional UI views and do not re-create them every time
when the cell is filled with data. Plus, the layout in your first section varies depending on whether you want to input password and e-mail or just display them. You will still have to deal with those variations.
If cell == nil - meaning if a cell is re-used - then first clean it from every UI item that you may have added before. You can do that by tagging your UIViews with - let's say 99 - (anything different from 0 should do) upon creation and when reusing enumerate over all subviews and remove those, which have the tag 99. Despite that you can stick with the code that you have already made.
The easiest fix is:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"GenericCell"] ;
//some more code
return cell;
}
This would remove the reusability from the tableview, but since it's a limited settings view, it can be ok. I would still advice taking 1 or 2 from Hermann Klecker's solutions.
If you also need to persist UIControl state then use
static NSString *MyIdentifier = [NSString stringWithFormat:#"GenericCell%d",indexPath.row];
It will always return your unique table row and you can use it as required.
Try to remove all subviews from cell before reusing it. Try the code :
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
}
else
{
[cell.contentView.subviews makeObjectsPerformSelector:#selector(removeFromSuperview)];
}
Remove all subviews before adding the subviews on cell.
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier]autorelease];
}
else
{
//To remove the subview of cell.
for (UIView *vwSubviews in [cell.contentView subviews])
{
[vwSubviews removeFromSuperview];
}
}
It may solves your problem.
Actually you have some bad code here.
In the mehthod
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Unless it is not in if (cell == nil), you should NOT initialize and use any
-(void)addSubview:(UIView*)view
Why?
The cells are views which are reused from tableview. So If you add some subview, next time while reusing the cell, it will be added more subviews on it. Simply they are overlapped and may cause MEMORY LEAK.
Do not forget that cells are reusable. So;
if I have the following code unless I do not set text somewhere else. It is expected to all cells has the text in their text labels "this is a text". Because they are reusable.
if (someChangingBool) {
cell.textLabel.text = #"this is a text";
}
So I need to have an else for that if which sets the text something else.
For more Information.
This is probably caused by poor design, but when I scroll my table too fast, and then scroll back to the top, the view that is placed in the last table cell is also placed over the first table cell in the tableView.
I think it is probably caused by my use of if statements to put some static content in the first section and dynamic content in the second section.
Any help is appreciated.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
if (indexPath.section == 0) {
if (indexPath.row == 0) {
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(10, 13, 282, 20)];
textField.clearsOnBeginEditing = NO;
textField.placeholder = #"enter template name";
textField.font = [UIFont systemFontOfSize:15.0];
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.delegate = self;
textField.text = [selectedTemplate name];
[textField addTarget:self action:#selector(nameDidChange:) forControlEvents:UIControlEventEditingChanged];
[cell.contentView addSubview:textField];
} else {
cell.textLabel.text = #"Add a new question";
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
} else {
NSString *label = [[sortedQuestions valueForKey:#"questionText"] objectAtIndex:indexPath.row];
CGSize stringSize = [label sizeWithFont:[UIFont boldSystemFontOfSize:15] constrainedToSize:CGSizeMake(230, 9999) lineBreakMode:NSLineBreakByWordWrapping];
UITextView *textV=[[UITextView alloc] initWithFrame:CGRectMake(5, 5, 230, stringSize.height+10)];
textV.font = [UIFont systemFontOfSize:15.0];
textV.text=label;
textV.textColor=[UIColor blackColor];
textV.editable = NO;
textV.userInteractionEnabled = NO;
textV.backgroundColor = [UIColor colorWithRed:0.97f green:0.97f blue:0.97f alpha:1.00f];
[cell.contentView addSubview:textV];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
return cell;
}
Here is what I ended up doing based on Wienke's recommendation. I added 3 prototype cells to my storyboard named Cell,Cell2,Cell3.
Relevant code:
static NSString *CellIdentifier = #"Cell";
static NSString *CellIdentifier2 = #"Cell2";
static NSString *CellIdentifier3 = #"Cell3";
UITableViewCell *cell;
if (indexPath.section == 0 && indexPath.row == 0) {
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
} else if (indexPath.section == 0 && indexPath.row == 1) {
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2 forIndexPath:indexPath];
} else if (indexPath.section == 1) {
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier3 forIndexPath:indexPath];
}
I also added this to check my dynamic cells and remove any lingering subviews that could be hanging around before adding the new subview.
if ([cell.contentView subviews]){
for (UIView *subview in [cell.contentView subviews]) {
[subview removeFromSuperview];
}
}
I know this already has an accepted answer, but I figured I would go slightly deeper into the "why" this was happening, and the solution.
In layman's terms, the UITableView refreshing was lagging with the presentation speed asked. In other words, due to the rapid scroll, the table view was expected to repopulate the content faster than it could sort through the expected cell to reuse for it's respective index (row).
The simplest solution, which Wienke touched on, is to create different cell identifiers for the first, let's say three (3) cells. This will allow the table view to be able to clearly differentiate between the 3 cells, preventing any cell misplacement.
Perhaps the best approach here would be to assign relevant cell identifiers to each cell (depending on the context and the number of cells). This way the table view knows precisely which cell (with it's respective ID) goes where. Something as simple as the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellID = [NSString stringWithFormat:#"cell%lu", indexPath.row];
__kindof UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (!cell) {
// Create your cell here.
cell = [...allocate a new cell...] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
return cell;
}
It looks like a cell that was layed out for, say, section 0 row 0 is being dequeued and used for, say, section 0 row 1, which does not replace all of the settings that were made for it when it was holding section 0 row 0 material.
You might want to consider using 3 separate cell identifiers, one for section 0 row 0, one for section 0 row 1, and one for all the rest. You'll need a preliminary set of if statements (or switch-case statements) so that you use the right identifier when calling dequeueReusableCellWithIdentifier:.
is it possible to change background image of each sections in uitableview?
I want to add background image for each sections in uitableview
does anyone know how can I do that?
Thanks in advance!
like this picture --> put different background images for wednesday , Thursday and friday separately
Edit I want to add image 1 for wednesday image 2 for Thursday image 3 for friday and .....
how can I specify that ?
Edit
this the code for creating sections header I want to have background also
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if(section == 0)
return #"Monday";
else if(section == 1){
return #"Tuesday";
}else if(section == 2){
return #"Wednesday";
} else if(section == 3){
return #"Thuesday";
} else if(section == 4){
return #"Friday";
} else if(section == 5){
return #"Saturday";
}else
return #"Sunday";
}
You could change the background in the cellForRowAtIndexPath delegate method based on the indexPath, like so:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"TaskCellRow";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
int maxRow = 3;
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed: [NSString stringWithFormat: #"background_image%i.png", MIN(indexPath.row, maxRow)]]];
}
else
{
UIImageView *background = (UIImageView *)cell.backgroundView;
background.image = [UIImage imageNamed: [NSString stringWithFormat: #"background_image%i.png", MIN(indexPath.row, maxRow)]];
}
return cell;
}
// To change header backgrounds
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
int maxRow = 3;
UIImageView *headerView = [[UIImageView alloc] initWithImage:[UIImage imageNamed: [NSString stringWithFormat: #"background_image%i.png", MIN(section, maxRow)]]];
return headerView;
}
You would then just create images, numbered for the desired amount header/rows, ie. background_image0.png, background_image1.png, background_image2.png, ... and so forth. The MIN will cap the amount off at the whatever you decide is the max backgrounds. Hope that helps.
EDIT: Changed cellForRowAtIndexPath based on Henri's comments. I overlooked that, thanks! This is for ARC compatibility.
You can use:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
to specify any kind of UIView for a section header. This other delegate method:
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
lets you specify the height.
Just alloc/init the UIView in the first one using the table's width and the height from the second method and then add any number of views to it, such as a UIImageView for a background then a label for the title.
Iterating (and mostly correcting) example given by ezekielDFM. Note, this code is not ARC compatible (which previous example may have been).
// To change cell backgrounds
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"TaskCellRow";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
int maxRow = 3;
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UIImageView *imageView = [[UIImageView alloc] initWithImage: [UIImage imageNamed: [NSString stringWithFormat: #"background_image%i.png", MIN(indexPath.row, maxRow)]]] autorelease];
cell.backgroundView = imageView;
} else {
// Reusing, we need to swap out the image of the background
cell.backgroundView.image = [UIImage imageNamed: [NSString stringWithFormat: #"background_image%i.png", MIN(indexPath.row, maxRow)]];
}
return cell;
}
// To change header backgrounds
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
int maxRow = 3;
UIImageView *headerView = [[[UIImageView alloc] initWithImage:[NSString stringWithFormat:#"background_image%i.png", MIN(section, maxRow)]] autorelease];
return headerView;
}
As i guess it is not possible to change the background image for Table view Sections. If you want to do such a requirement, please try with cell for row as Sections. i.e. for each row treat as section of table & in that add 1 more table view with different tag. It will full your req. or else for each row take
