How to add images in UITableViewCells programmatically in iOS - ios

Question

I need to add different images in UITableViewCells programmatically. How can I do that. I am trying some code. But the images are not displayed in UITableViewCells.
This is my code below.
-(void)viewDidLoad
{
arrImages=[[NSMutableArray alloc]initWithObjects:#"image.png",#"image2.png",#"image3.png",#"image4.png",#"image5.png",#"image6.png",#"image7.png",#"image8.png" nil];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier=#"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"identifier"];
}
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 48, 48)];
cell.imageView.image = [UIImage imageNamed:[arrImages objectAtIndex:indexPath.row]];
return cell;
}

Answer 1

This is what you probably want:
- (void)viewDidLoad
{
self.arrImages = [[NSMutableArray alloc] initWithObjects:#"image.png",#"image2.png",#"image3.png",#"image4.png",#"image5.png",#"image6.png",#"image7.png",#"image8.png" nil];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString* CellIdentifier = #"Cell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]
}
cell.imageView.image = [UIImage imageNamed:[self.arrImages objectAtIndex:indexPath.row]];
return cell;
}
P.S.: Next time, please make some effort on formatting the source code, explaining what is wrong, what have you tried, what would you like to accomplish. Thanks

Create a property of NSArray in your .h file
#property NSArray *imgArray;
synthesize in your .m file
#synthesize imgArray;
write this in your viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
// Initialize images...
imgArray = [NSArray arrayWithObjects:#"yourFirstImageName.png", #"yourSecondImageName.png", #"yourThirdImageName.png",....., #"yourSeventhImageName.png", nil];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 48, 48)]; // your cell's height should be greater than 48 for this.
imgView.tag = 1;
[cell.contentView addSubview:imgView];
imgView = nil;
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(x, y, width, height)];
lbl.backgroundColor = [UIColor clearColor];
[lbl setTag:2];
[cell.contentView addSubview:lbl];
lblDisch = nil;
}
UIImageView *_imgView = (UIImageView *)[cell.contentView viewWithTag:1];
_imgView.image = [UIImage imageNamed:[imgArray objectAtIndex:indexPath.row]];
UILabel *_lbl = (UILabel *)[cell.contentView viewWithTag:2];
_lbl.text = [arrFont objectAtIndex:indexPath.row]; // arrFont is your array
return cell;
}
Hope this will help you.

Create a #property of NSMutableArray in your .h file.
NSMutableArray *data;
Write This Code your .m file.
- (void)viewDidLoad
{
data = [[NSMutableArray alloc]initWithObjects:#"1.jpg",#"2.jpg",#"3.jpg",#"4.jpg",#"5.jpg",#"6.jpg",#"7.jpg",#"8.jpg",#"9.jpg",#"10.jpg",#"11.jpg",#"12.jpg",#"13.jpg",nil];
[super viewDidLoad];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [data count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.imageView.image = [UIImage imageNamed:[data objectAtIndex:indexPath.row]];
return cell;
}
