How to change UITableViewCell Image to Circle in UITableView

Question

My code works for the most part.

• The issue I am having is the images start out as square, and change to circle when I scroll the table or refresh it.

Answer 1

Set the image view to a circle inside the async call where you set the image.

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{

    NSString * imageString = [tweet valueForKeyPath:@"user.profile_image_url"];
    NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:imageString]];

    if (imageData != nil)
    {
        dispatch_async(dispatch_get_main_queue(), ^{

            cell.imageView.image = [UIImage imageWithData: imageData];
cell.imageView.layer.cornerRadius = cell.imageView.frame.size.width / 2.0;
cell.imageView.layer.borderWidth = 3.0;
cell.imageView.layer.borderColor = [UIColor colorWithRed:157.0/255.0 green:34.0/255.0 blue:53.0/255.0 alpha:1.0]
.CGColor;
cell.imageView.clipsToBounds = YES;
            [cell setNeedsLayout];
        });
    }
});
