How to get the original attached view in gesture recognizer in iphone?

Question

By the following code I attatched a button in a gesture recognizer:

UILongPressGestureRecognizer *longPress=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(addLongpressGesture:)];
[longPress setDelegate:self];
[BUTTON addGestureRecognizer:longPress];

Here is my addLongpressGesture method:

- (void)addLongpressGesture:(UILongPressGestureRecognizer *)sender {

UIView *view = sender.view;

CGPoint point = [sender locationInView:view.superview];

if (sender.state == UIGestureRecognizerStateBegan){ 

      // GESTURE STATE BEGAN

}
}

by this code sender.view I am getting the attached view as UIView But I want the view as it was attached (UIButton), how do I get the UIView as UIButton?

Answer 1

change this

UIView *view = sender.view;

to this

UIButton *btn = (UIButton*)sender.view;

Answer 2

Like this:

UIButton *button = (UIButton*)sender.view;

UIButton is a UIView. If you know that your gesture recognizer is attached to a button, this cast is safe.

Answer 3

UIView* yourView = yourGestureRecogniser.view;

Since each gestureRecogniser has only one view property, this explains why a gesture recogniser can be added to 1 view only.
