The app freeze after popViewControllerAnimated in iOS9

Question

My app edited from Spika app and it work fine before iOS9. But now I got a very serious issue in iOS9.

My app will freeze always after run popViewControllerAnimated or dismissViewControllerAnimated that view with UITextField, UITextView or UISwitch. It's very strange and got no any error in Xcode Console.

I had try to create a new sample to test the operations in pop or dismiss view controller in iOS9 and it work fine. After I testing and I am sure it's a conflict with the libraries of spika app and iOS9 but I didn't know where is the problem.

Had anyone any idea to help to resolve this issue?

Answer 1

Today I finally had been resolved this issue. In the UIView+Extensions.m of spika

-(void) removeAllGestureRecognizers {    
    while (self.gestureRecognizers.count != 0) {
        [self removeGestureRecognizer:self.gestureRecognizers[0]];
    }    
}

This function cause the UIView freeze when leave one view in iOS9. Thanks god or I will go crazy.
