In my iPhone app I use beginTrackingWithTouch, etc. to handle a swipe and rotate an OpenGL object. I wanted to add pinch and rotate gestures to do the obvious things. I created a UIRotationGestureRecognizer and a UIPinchGestureRecognizer, added them to the control view and wrote the action methods. They worked just fine.
Then I realized that they operated exclusively. That is, once a rotation was recognized a pinch would not be recognized until the touch set was ended and another begun. The delegate method shouldRecognizeSimultaneouslyWithGestureRecognizer is there to let you specify that both should be handled, so I wrote one that simply returns YES. That also works, but I see an odd behavior. The app works normally until I do a pinch-rotate. From then on all touches seem to be greatly delayed, a significant fraction of a second. Does the "simultaneous" method invoke something that hangs around and impedes touches? thanks for any comments, David _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
