Ripple Effect on ipad

I want to create a rippl开发者_StackOverflow中文版e effect on a UIImageView from the point where user touches on the screen. what is the best and simple method for doinf this.

Please look at this question.

Hope it helps

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSSet *allTouches = [event allTouches];
    UITouch *touch = [[event allTouches] anyObject];        
    CGPoint lastPoint = [touch locationInView:self.view];   
    //animation code
}

Using above method you have set UIimageView center on lastPoint and play your animation code. It will work that u want.
