How to Show image when tapped?

How would you show an image where the user tapped the screen? Using the TouchesEnded or TouchesBegan? When the user taps the middle of the screen an image will pop up where it touched.

Any help on this would be great!

You can get the touch location in touchesBegan, then it's just a simple matter of adding a UIImageView subview and setting it's center to the touch location.

You could make the whole screen a UIButton and depending on what kind of touch you are looking for (usually touch up inside) you can have the touch event also be passed to it:

Code:

- (void) tapped:(id)sender withEvent:(UIEvent *)event

from the event object you can get the touched coordinates, locationInView is your friend.
