Circular UIImageView in UITableView without performance hit?

Use this code.. This will be helpful..

    UIImage* image = ...;
    UIGraphicsBeginImageContextWithOptions(imageView.bounds.size, NO, 1.0);
    // Add a clip before drawing anything, in the shape of an rounded rect
    [[UIBezierPath bezierPathWithRoundedRect:imageView.bounds
                                cornerRadius:50.0] addClip];
    // Draw your image
    [image drawInRect:imageView.bounds];

    // Get the image, here setting the UIImageView image
    imageView.image = UIGraphicsGetImageFromCurrentImageContext();

    // Lets forget about that we were drawing
    UIGraphicsEndImageContext();

It works fine for me. :)

To Add border

self.ImageView.layer.borderWidth = 3.0f;

self.ImageView.layer.borderColor = [UIColor whiteColor].CGColor;

For Circular Shape

self.ImageView.layer.cornerRadius = self.ImageView.frame.size.width / 2;
self.ImageView.clipsToBounds = YES;

Simply set the cornerRadius to half of the width or height (assuming your object's view is square).

For example, if your object's view's width and height are both 50:

itemImageView.layer.cornerRadius = 25;

Update - As user atulkhatri points out, it won't work if you don't add:

itemImageView.layer.masksToBounds = YES;
