Question

I have a gesture recogniser to detect a tap on a UIImageView, however I force a position change of the image when the orientation of the iPad changes but this causes the gesture recogniser to repositioned incorrectly. How can I resolve this?

EDIT:

strapTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(strapTap:)];
[(UITapGestureRecognizer *)strapTap setNumberOfTapsRequired:1];
strapTap.delegate = self;
[leatherButtonedStrap addGestureRecognizer:strapTap];

This above is how I setup the gesture, adding it to my UIImageView. However, something which might cause a stir is that I add the this view to my main view, remove it and then re-add it when the user presses a certain button. Hard for you to understand whats happening unless you saw the entire class, but let me know if this is enough to go on or not.

Answer 1

Make sure when you’re calling locationInView: in strapTap: to send the leatherButtonedStrap as the parater:

CGPoint location = [recognizer locationInView:leatherButtonedStrap];

So that the location is relative to leatherButtonedStrap’s coordinate system an not it’s superview’s.
