UPDATE

I’m looking for the best way to detect more than one finger on a particular view at time in this case the view is UITextview. I’m not detecting taps or pinching, just the fact that more than one touch is happening. In this case, i set textview.multipleTouchEnabled=NO and then i didn’t set gesture anywhere. And i didn’t set the zoom in UITextView. And i didn’t override some of touches method in that controller.

the problem is, when i touch my app on the device using a touch like pinching, or touch use more than one finger, the app got crashed and no error log in the debugger console. I try to debug this app, but i dont know what i’m looking for.

UPDATE 2

i was wrong about the object that get user touch, i was thought that the object is UITextview, but UIWebview. So, this problem is happen when i touch UIWebview with 2 fingers. I have forwarded the touches event using this suggestion. But i still confuse, how to clear up this crash on my app.
Can somebody help me??

Thank You

Regard,

Risma

    Check that text view zoom level is set by default it’s min and max zoom is 1.

    In pinch gesture you have to set scale factor.
