Set UIImageView Size in UITableViewCell when UIImage loaded from URL?

Question

Loading images from URL into a uiimage and then adding those images to a uitableviewcell uiimageview, like below code. I do not know the image sizes, but need to force them to

Answer 1

I had this problem when I was mistakenly using the imageView property of the cell rather than the property for the custom UIImageView I created in the storyboard. When I used the proper reference to the custom view, it all worked as expected. I suspect some of you may have done similar.

Answer 2

I had the same problem and this worked perfectly for me;

select the UIImage and go to attributes inspector and check "Clip Subviews"

make sure you have constraints set for the image's size.

Answer 3

Found the answer looking at Apples example project "LazyTableImages"

NSURL *url = [NSURL URLWithString: item.imgPath];
UIImage *thumbnail = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]];
if (thumbnail == nil) {
    thumbnail = [UIImage imageNamed:@"noimage.png"] ;
}
CGSize itemSize = CGSizeMake(40, 40);
UIGraphicsBeginImageContext(itemSize);
CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
[thumbnail drawInRect:imageRect];
cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

return cell;
