- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [tableData count];
}
- (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];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
cell.imageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
return cell;
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}

Answer 1

just set Frame of your cell imageView in cellForRowAtIndexPart section
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewStylePlain reuseIdentifier:CellIdentifier];
}
cell.imageView.frame = CGRectMake(50, 10, 200, 50);
return cell;
}

Answer 2

try this line just above "return cell;":
cell.imageView.frame = CGRectMake(0,0,32,32);

Answer 3

I actually have the same problem right now, the current answers will not work because all of the standard views in a UITableViewCell are resized in the layoutSubviews method, so changing the frame of the view, at least in the tableView:cellForRowAtIndexPath: will not work.
As far as I know you have the following options:
Change the frame of the imageView by subclassing the UITableViewCell in the layoutSubviews after the [super layoutSubviews] call, I have tried this and you have to also move the textLabel because it will be positioned in the wrong place since the image is now bigger/smaller.
Don't use the imageView, rather create your own UIImageView, of course you will have to reposition the textLabel or rather create your own UILabel, the downside is that you have to be aware of the placement and size of your UIImageView and UILabel when the device is rotated, tableView is resized, etc.
Pad your images with transparency so all are the same size and be able to take advantage of the default UITableViewCell automatic layout
Resize your images on the spot, like in this answer: Incorrect size of Images in TableView
I think I'll use the third option for my own case, since I am in control of the images used in each cell.
