    With the following method stated below you can crop an UIImageView. 

    -(UIImage *)cropedImage:(UIView *)view{
    UIGraphicsBeginImageContextWithOptions(view.frame.size, imageView.opaque, 4.0);

    CGContextRef c = UIGraphicsGetCurrentContext();

    CGContextConcatCTM(c, CGAffineTransformMakeTranslation(-view.frame.origin.x, -view.frame.origin.y));

    [imageView.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage * img = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return img;
}

    This method will require an UIView which will slide over the UIImageView to get a frame.

    Happy coding...
