Table check box just for one section objective-c - 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
viewDidLoad
- (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:#"Red",#"Black",#"Blue", nil] forKey:absKey];
[keys addObject:staKey];
[keys addObject:endKey];
[keys addObject:absKey];
[self setSectionKeys:keys];
[self setSectionContents:contents];
}
cellForRowAtIndexPath:
- (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]];
CheckBoxTableViewCell *cell = (CheckBoxTableViewCell*)[tableView
dequeueReusableCellWithIdentifier:#"CheckBoxTableViewCell"];
cell.imageView.image=[UIImage imageNamed:#"emptycheck-box.png"];
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;
}
}

Implementing UIWebView on a custom UITableViewCell

I have this UIWebView inside a custom UITableViewCell that I've created.
The problem is, when I implement the UIWebView in "MyMain", it's working but when I scroll the text is readded again and again on over the cells.
When I implement the UIWebView in the custom cell class itself it's not showing it at all.
UITableViewCustomCell.h
#property (nonatomic, weak) IBOutlet UIWebView *wvMainText;
#property (nonatomic, strong) NSString *wvTitle;
#property (nonatomic, strong) NSString *wvPrice;
UITableViewCustomCell.m
#synthesize wvMainText = _wvMainText;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self)
{
// THIS IS WHERE I IMPLEMENT THE WEBVIEW?
}
return self;
}
MyMain
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"myListCell";
UITableViewCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray* views = [[NSBundle mainBundle] loadNibNamed:#"UITableViewCustomCell" owner:nil options:nil];
for (UIView *view in views) {
if([view isKindOfClass:[UITableViewCell class]])
{
cell = (UITableViewCustomCell *)view;
}
}
}
cell.wvTitle = [[self.arrList objectAtIndex:indexPath.row] valueForKey:#"title"];
cell.wvPrice = [[self.arrList objectAtIndex:indexPath.row] valueForKey:#"price"];
wv.scrollView.scrollEnabled = NO;
NSString *htmlString = [NSString stringWithFormat:
#"<html><body>%#,%#</body></html>", self.wvTitle, self.wvPrice];
[wv loadHTMLString:htmlString baseURL:nil];
[wv setBackgroundColor:[UIColor clearColor]];
[wv setOpaque:NO];
return cell;
}
Try this...It may solve your issue.
In your cellForRowAtIndexPath method please do changes like this....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"myListCell";
UITableViewCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray* views = [[NSBundle mainBundle] loadNibNamed:#"UITableViewCustomCell" owner:nil options:nil];
for (UIView *view in views) {
if([view isKindOfClass:[UITableViewCell class]])
{
cell = (UITableViewCustomCell *)view;
}
}
cell.wvTitle = [[self.arrList objectAtIndex:indexPath.row] valueForKey:#"title"];
cell.wvPrice = [[self.arrList objectAtIndex:indexPath.row] valueForKey:#"price"];
wv.scrollView.scrollEnabled = NO;
NSString *htmlString = [NSString stringWithFormat:
#"<html><body>%#,%#</body></html>", self.wvTitle, self.wvPrice];
[wv loadHTMLString:htmlString baseURL:nil];
[wv setBackgroundColor:[UIColor clearColor]];
[wv setOpaque:NO];
}
return cell;
}

adding check box to one of sections in UITableView

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;
}
}

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.

Loading data in NSUserDefaults

i have done the coding to save the highscore in NSuserdefaults, but i am not sure how can i load the data from the nsuserdefaults and display it in a table. PLease help.
NSString *name;
name = nametextbox.text;
NSDictionary *player = [NSDictionary dictionaryWithObjectsAndKeys: [NSString stringWithFormat:#"%#", name], #"name",[NSString stringWithFormat:#"%d", myScore], #"score",nil];
[highScore addObject:player];
NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:#"score" ascending:NO];
[highScore sortUsingDescriptors:[NSArray arrayWithObject:sort]];
[sort release];
[[NSUserDefaults standardUserDefaults] setObject:highScore forKey:#"highScore"];
You should be able to load it just the way you'd expect (like accessing a value in an NSDictionary):
NSArray *highScore = [[NSUserDefaults standardUserDefaults] objectForKey:#"highScore"];
Update
To display the data from this array in a table view, you'll need to create a view controller and use the array as your data source. The easiest way to do this is by subclassing UITableViewController. This should get you started on the implementation of that controller:
// HighScoreViewController.h
#interface HighScoreViewController : UITableViewController {
NSArray *highScores;
}
#property (nonatomic, retain) NSArray *highScores;
#end
.
// HighScoreViewController.m
#import HighScoreViewController.h
static const NSInteger kNameLabelTag = 1337;
static const NSInteger kScoreLabelTag = 5555;
#implementation HighScoreViewController
#synthesize highScores;
- (void)viewDidLoad {
[self setHighScores:[[NSUserDefaults standardUserDefaults]
objectForKey:#"highScore"]];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.highScores count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"PlayerCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cel == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:cellIdentifier] autorelease];
// Create UILabels for name and score and add them to your cell
UILabel *nameLabel = [[UILabel new] autorelease];
[nameLabel setTag:kNameLabelTag];
[cell.contentView addSubview:nameLabel];
UILabel *scoreLabel = [[UILabel new] autorelease];
[scoreLabel setTag:kScoreLabelTag];
[cell.contentView addSubview:scoreLabel];
// Set other attributes common to all of your cells here
// You will also need to set the frames of these labels (nameLabel.frame = CGRectMake(...))
}
NSDictionary *player = [self.highScores objectAtIndex:indexPath.row];
NSString *name = [player objectForKey:#"name"];
NSString *score = [player objectForKey:#"score"];
[(UILabel *)[cell.contentView viewWithTag:kNameLabelTag] setText:name];
[(UILabel *)[cell.contentView viewWithTag:kScoreLabelTag] setText:score];
return cell;
}
#end
A key thing to remember with UITableView is that cells get reused, so you need to be careful about where you initialize/configure your cell's subviews.
