Try this method:

-(UIImage *)drawImage:(UIImage*)profileImage withBadge:(UIImage *)badge
{
    UIGraphicsBeginImageContextWithOptions(profileImage.size, NO, 0.0f);
    [profileImage drawInRect:CGRectMake(0, 0, profileImage.size.width, profileImage.size.height)];
    [badge drawInRect:CGRectMake(0, profileImage.size.height - badge.size.height, badge.size.width, badge.size.height)];
     UIImage *resultImage = UIGraphicsGetImageFromCurrentImageContext();
     UIGraphicsEndImageContext();
     return resultImage;
}

You can use it by:

UIImage *myBadgedImage = [self drawImage:profileImage withBadge:badgeImage];
