Question

I m using UIimageview on top of UIWindow. I want to handle touch event for that Imageview, but m not able to do it.

When i use UIimageView on UIview, we can use touchBegan, touchEnded but how to handle it when it is on UIWindow instead of UIView.

Thanks..

If you just want to handle the tap, you have to set,

imageView.userInteractionEnabled = YES;

By default UIImageView has the userInteractionEnabled property set to NO. And you can add a tap gesture recognizer to it,

UITapGestureRecognizer *tgr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(anyMethod)];
[imageView addGestureRecognizer:tgr];
[tgr release];

If you want to move the image, you can use UIPanGestureRecognizer.
