iOS - UIPanGestureRecognizer : drag during animati

问题:

i use UIPanGestureRecognizer to move an object along the path drawn by the user. But this object is animating and i need to interact with it during animation. Is it possible? I already try to use UIViewAnimationOptionAllowUserInteraction but no results.

回答1:

Yes it is possible. But I would use CABasicAnimation for animating the object and not the UIView animationWith... and then add the UIPanGestureRecognizer to the object. So some example code:

// Configure the animation and add it to the layer.
CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"position"];
anim.fromValue = ...
anim.duration = ...
[view.layer addAnimation:anim forKey:@"some key"];
// Then add the UIPanGestureRecognizer to that view.
