Question

I am using below code to add number of images in a single cell content view.

    cell.imageView1.image = [UIImage imageNamed:@"testImg1"];
            cell.imageView2.image = [UIImage imageNamed:@"testImg2"];
            cell.imageView3.image = [UIImage imageNamed:@"testImg3"];
            cell.imageView4.image = [UIImage imageNamed:@"testImg4"];
            cell.imageView5.image = [UIImage imageNamed:@"testImg5"];  
.............................  
............................  
cell.imageView20.image = [UIImage imageNamed:@"testImg20"];  

How to use for loop with stringWithFormat to make my code look conscise something like:

for(imageCounter = 1; imageCounter <21, imageCounter++)  
{  
cell.imageView(imageCounter).image = [UIImage imageNamed:@"testImg(imageCounter)"];  
}  

Any Suggestion?

To reach references of the different image views inside the loop you have to either out them in an array or tag them than you can either go:

  NSArray *cellImageViews;
  for(int imageCounter = 1; imageCounter < 21; imageCounter++)
  {
    [[cellImageViews objectAtIndex:imageCounter-1] setImage:[UIImage imageNamed:[NSString stringWithFormat:@"testImg%d", imageCounter]]];
  }

or

  for(int imageCounter = 1; imageCounter <21; imageCounter++)
  {
    [((UIImageView *)[cell viewWithTag:imageCounter]) setImage:[UIImage imageNamed:[NSString stringWithFormat:@"testImg%d", imageCounter]]];
  }
