Question

I temporarly added some values to the UITableViewCell programmatically. But I need to add images to each cell. How can I do that?

Here is my code. .h file

 @interface BidalertsViewController : UIViewController       <UITableViewDelegate,UITableViewDataSource> {
    NSArray *listData;
}
@property(nonatomic, retain) NSArray *listData; 
@end

.m file

 @synthesize listData;

- (void)viewDidLoad {
UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(5,0,310,28)];
newView.backgroundColor=[UIColor whiteColor];
UITextView *mytext = [[UITextView alloc] initWithFrame:CGRectMake(0.0, 0.0, 100.0, 25.0)];
mytext.backgroundColor = [UIColor clearColor];
mytext.textColor = [UIColor blackColor];
mytext.editable = NO;
mytext.font = [UIFont systemFontOfSize:15];
mytext.text = @"Asset Name";
[mytext release];
[newView addSubview:mytext];

[self.view addSubview:newView];
[newView release];


NSArray *array = [[NSArray alloc] initWithObjects:@"iPhone", @"iPod", @"iPad",nil];
self.listData = array;
[array release];
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning {
     [super didReceiveMemoryWarning];
}
 - (void)dealloc {
  [listData dealloc];
  [super dealloc];
}


 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
return [self.listData count];
 }

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if (cell == nil) { cell = [[[UITableViewCell alloc]
                            initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier] autorelease];
}
NSUInteger row = [indexPath row]; 
cell.textLabel.text = [listData objectAtIndex:row]; 
return cell;

UIImageView *imv = [[UIImageView alloc]initWithFrame:CGRectMake(3,2, 20, 25)];
imv.image=[UIImage imageNamed:@"user.jpg"];
[cell.contentView addSubview:imv];
[imv release];
 }
@end

The code didn’t add images to the cell. What’s the problem? How can I do to add custom image to cell?

Move return cell; at the end of the method:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
    if (cell == nil) { cell = [[[UITableViewCell alloc]
                                initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier] autorelease];
    }
    NSUInteger row = [indexPath row]; 
    cell.textLabel.text = [listData objectAtIndex:row]; 


    UIImageView *imv = [[UIImageView alloc]initWithFrame:CGRectMake(3,2, 20, 25)];
    imv.image=[UIImage imageNamed:@"user.jpg"];
    [cell.contentView addSubview:imv];
    [imv release];

    return cell;
}
