adding check box to one of sections in UITableView - objective-c

I create a table view controller programmatically that contains different sections I want to add 3 rows with check mark box in my third sections (I used storyboard!)
would you please give me some hint that how can I do that ..
my question is how can I set checkbox in left side for my third sections
here is the picture:instead of Please set your code: having 3 rows with check mark box in Absence Code sections
Here is my view in storyboard:
Here is the code:
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableArray *keys = [[NSMutableArray alloc] init];
NSMutableDictionary *contents = [[NSMutableDictionary alloc] init];
NSString *staKey = #"Start";
NSString *endKey = #"End";
NSString *absKey= #"Absence";
[contents setObject:[NSArray arrayWithObjects:#"Time: 08:00 Date: Fri,3 Aug, 2012", nil] forKey:staKey];
[contents setObject:[NSArray arrayWithObjects:#"Time: 17:57 Date: Fri,3 Aug, 2012", nil] forKey:endKey];
[contents setObject:[NSArray arrayWithObjects:#"Please set your code", nil] forKey:absKey];
[keys addObject:staKey];
[keys addObject:endKey];
[keys addObject:absKey];
[self setSectionKeys:keys];
[self setSectionContents:contents];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
[[cell textLabel] setText:contentForThisRow];
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSMutableArray *weekArray = [[ NSMutableArray alloc] initWithObjects: #"Start Time", #"End Time",#"Absence Code",
nil];
return [weekArray objectAtIndex:section];
}
- (UITableViewCellAccessoryType)tableView:(UITableView *)tv accessoryTypeForRowWithIndexPath:(NSIndexPath
*)indexPath {
return UITableViewCellAccessoryDisclosureIndicator;
}
Thanks in advance!

Each checkbox cell should be a Custom TableViewCell. Then simply drop an ImageView and a Label in the TableViewCell and use didSelectRowAtIndex: to toggle the image between checked/unchecked.

EDIT:
Check Selecting multiple rows of a UITableView link get helped.
Do this: change code in below method:
- (UITableViewCellAccessoryType)tableView:(UITableView *)tv accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath {
if(indexPath.section ==2)
{
return UITableViewCellAccessoryCheckMark;
}
else
{
return UITableViewCellAccessoryDisclosureIndicator;
}
}

custom cell not appear when loading new views objective-C

I create a UITableView programmatically with different cells and sections that connects to the other views in storyboard
But if you check the story board absence view has custom cell with check box sections that it's not appear here
My question is:
why it doesn't shows the custom cell?,would you please helping me
Thanks in advance!
Here is my code:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString: #"WorkTime"]){
[segue.destinationViewController setTitle:#"WorkTime"];
}if([segue.identifier isEqualToString: #"Absence"]){
[segue.destinationViewController setTitle:#"Absence"];
}if([segue.identifier isEqualToString: #"Compensation"]){
[segue.destinationViewController setTitle:#"Compensation"];
}
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableArray *keys = [[NSMutableArray alloc] init];
NSMutableDictionary *contents = [[NSMutableDictionary alloc] init];
NSString *workKey = #"work";
NSString *absKey = #"absence";
NSString *comKey = #"compensation";
[contents setObject:[NSArray arrayWithObjects:#"Work Time", nil] forKey:workKey];
[contents setObject:[NSArray arrayWithObjects:#"Absence", nil] forKey:absKey];
[contents setObject:[NSArray arrayWithObjects:#"Compensation", nil] forKey:comKey];
[keys addObject:workKey];
[keys addObject:absKey];
[keys addObject:comKey];
[self setSectionKeys:keys];
[self setSectionContents:contents];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
[[cell textLabel] setText:contentForThisRow];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
_selectedIndex = indexPath.row;
[self.tableView reloadData];
//case1
[self performSegueWithIdentifier:#"WorkTime" sender:self];
//case2
[self performSegueWithIdentifier:#"Absence" sender:self];
//case3
[self performSegueWithIdentifier:#"Compensation" sender:self];
}
I think your problem is here
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
Your custom cell should have a unique cell identifier. You need to pass that unique cell identifier to -dequeueReusableCellWithIdentifier:.
What have you used as your cell identifier?
you should use NSLOG to be sure that you are going to different views, I think you are always in a same view is the reason that you cann't see the new changes

customising UITableViewCell with picture objective-C

I want to have custom cell in UITableView, I create my UIView via storyboard and I linked them to the code
I don't know why my picture does not appear
Would you please check my code ?
customise code .h
: UITableViewCell
#property (strong, nonatomic) IBOutlet UIImageView *weekImg;
#end
customise code .m
#synthesize weekImg;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
weekImg=[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"red.png"]];
}
return self;
}
My method: cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
WeekTableViewCell *cell = (WeekTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"WeekTableViewCell"];
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
[[cell textLabel] setText:contentForThisRow];
return cell;
}
I think this is because your code is just looking for previosuly created cells. at th start no cells will be created and wont be able to retrieve any this way.
WeekTableViewCell *cell = (WeekTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"WeekTableViewCell"];
if (cell == nil){
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"WeekTableViewCell" owner:nil options:nil];
for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[WeekTableViewCell class]])
{
cell = (WeekTableViewCell *)currentObject;
break;
}
}
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
[[cell textLabel] setText:contentForThisRow];
return cell;
this way create a new cell if there isnt a cell to re use
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.imageView.layer.cornerRadius=10.0f;
[cell.imageView.layer setMasksToBounds:YES];
cell.textLabel.text=[NSMUtableArray objectAtIndex:indexPath.row];
switch (indexPath.row)
{
case 0:
cell.imageView.image=[UIImage imageNamed:#"img1.png"];
break;
case 1:
cell.imageView.image=[UIImage imageNamed:#"img2.png"];
break;
case 2:
cell.imageView.image=[UIImage imageNamed:#"img3.png"];
break;
case 3:
cell.imageView.image=[UIImage imageNamed:#"img4.png"];
break;
default:
break;
}
}
cell.imageView.layer.cornerRadius=10.0f;
[cell.imageView.layer setMasksToBounds:YES];, it is used by QuartzCore.
The output of the cell like this, we can adjust the image size.

You can design a custom cell with 4 button in Xcode and map them to tableview
If you don't need user interaction, you can add them to a UIView (each is a subview with an appropriate frame), and make the container view the cell's backgroundview.
You can add the views directly to the cell's contentView and get user interaction, but you have to be careful as that area gets modified if there is a accessoryView etc.
It will be easier to design the custom cell and lay out your 4 buttons (since you need user interaction) in interface builder. Here's a very good tutorial to get you started. Give a tag number to each of the button so you will know which button was tapped later.
want to create 4 cell "button or picture" in one row in uiTableView like this picture:
but I don't know how can I do that :
First of all, you will need to create an objective-c class called MyCell. MyCell will be a subclass of UITableViewCell (this is very important)
In your MyCell.h,
#interface MyCell : UITableViewCell
#property (nonatomic, weak) IBOutlet UIButton *firstButton;
#property (nonatomic, weak) IBOutlet UIButton *secondButton;
#property (nonatomic, weak) IBOutlet UIButton *thirdButton;
#property (nonatomic, weak) IBOutlet UIButton *fourthButton;
#end
Then in your MyCell.m, just synthesize all those buttons.
In your tableview, where you want to use your customized cell, you need to modify the cellForRowAtIndexPath method. Replace your UITableViewCell with your custom MyCell. And don't forget to import "MyCell.h" into that tableview that you are using.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
MyCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(!cell)
{
cell = [[MyCell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
[cell.firstButton setTintColor:[UIColor redColor];
[cell.secondButton setTintColor:[UIColor redColor];
// and so on.. til you set all your four buttons.
return cell; }
And from there, your tableview should be showing your custom cell.

Table check box just for one section objective-c

I have a uiTableView with 3 sections and different rows, I want to add check box JUST to my third sections,
I create custom cell and I linke img and label
like this picture:
![enter image description here][1]
and my code for custom cell is :
.h
: UITableViewCell
#property (strong, nonatomic) IBOutlet UIImageView *checkBox;
#property (strong, nonatomic) IBOutlet UILabel *absenceCode;
#end
.m
#synthesize checkBox;
#synthesize absenceCode;
- (id)initWithCoder:(NSCoder *)coder
{
self = [super initWithCoder:coder];
if (self) {
// Initialization code
checkBox.image = [UIImage imageNamed:#"emptycheck-box.png"];
}
return self;
}
#end
and code for UITableViewController

cell.checkBox.image = image;
cell.absenceCode.text =#"Redddd";
cell.text =contentForThisRow;
return cell;
}
would you please help me
Thanks in advance!
Something like the following should do what you want.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *key = [[self sectionKeys] objectAtIndex:[indexPath section]];
NSArray *contents = [[self sectionContents] objectForKey:key];
NSString *contentForThisRow = [contents objectAtIndex:[indexPath row]];
if (indexPath.section != 2) {
//Set up default cell here.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier
cell.textLabel.text =contentForThisRow;
return cell;
}
else {
CheckBoxTableViewCell *cell = (CheckBoxTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"CheckBoxTableViewCell"];
cell.imageView.image=[UIImage imageNamed:#"emptycheck-box.png"];
cell.checkBox.image = image;
cell.absenceCode.text =#"Redddd";
return cell;
}
}

NSMutableDictionary and NSArray

I am splitting a String:
#"Sam|26|Developer,Hannah|22|Team Leader,Max|1|Dog"
and using NSMutableDictionary to display in a TableViewCell with 3 labels. Code:
- (void)viewDidLoad {
[super viewDidLoad];
NSString *test = #"Sam Parrish|26|Developer,Hannah Rajamets|22|Team Leader,Max Parrish|1|Dog";
testArray = [[NSArray alloc] init];
testArray = [test componentsSeparatedByString:#","];
dict = [NSMutableDictionary dictionary];
for (NSString *s in testArray) {
testArrayNew = [s componentsSeparatedByString:#"|"];
[dict setObject:[testArrayNew objectAtIndex:1] forKey:[testArrayNew objectAtIndex:0]];
[dict setObject:[testArrayNew objectAtIndex:2] forKey:[testArrayNew objectAtIndex:1]];
NSLog(#"Dictionary: %#", [dict description]);
}
[dict retain];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[dict allKeys] count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"CustomCell";
untitled *cell = (untitled *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"untitled" owner:nil options:nil];
for (id currentObject in topLevelObjects) {
if ([currentObject isKindOfClass:[UITableViewCell class]]) {
cell = (untitled *) currentObject;
break;
}
}
}
// Configure the cell.
cell.nameLabel.text = [[dict allKeys] objectAtIndex:[indexPath row]];
cell.ageLabel.text = [dict objectForKey:cell.nameLabel.text];
cell.jobLabel.text = [dict objectForKey:cell.ageLabel.text];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
this is displaying 6 TableViewCells when I run, 3 of which are perfect, the other 3 are an assortment of the data. i realise this is to do with the setObject: forKey: but can't seem to find the solution for this to work correctly.
any help much appreciated..
sam
I would store the data as an NSArray holding NSArrays....
- (void)viewDidLoad {
[super viewDidLoad];
NSString *test = #"Sam Parrish|26|Developer,Hannah Rajamets|22|Team Leader,Max Parrish|1|Dog";
data = [[NSMutableArray alloc] init];
for (NSString *s in testArray) {
[data addObject:[s componentsSeparatedByString:#"|"]];
}
}
Then in
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
use
// Configure the cell.
NSArray *cellData = [data objectAtIndex:indexPath.row];
cell.nameLabel.text = [cellData objectAtIndex:0];
cell.ageLabel.text = [cellData objectAtIndex:1];
cell.jobLabel.text = [cellData objectAtIndex:2];
If I understand you correctly, you're saying that the first three cells are correct and the other three shouldn't be shown at all? If that's the case, the problem is this:
return [[dict allKeys] count];
Shouldn't it be...
return [testArray count];
...in which case, you need to retain testArray.
In addition, you have a memory leak. You create an instance of NSArray, then you immediately leak it by assigning the return value of componentsSeparatedByString: to the same variable. Have you run the static analyser over your code?
