I have a view being added as a subView of a viewController. Both this subview and viewController all implement this method
- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
I found that when I tapped the subView, both these method will be called.
I want to call subview's touchesEnded only. How to achieve this nicely? (not to add a gesture in it)
In the touchesEnded, apple doc says this "If you override this method without calling super (a common use pattern), you must also override the other methods for handling touch events, if only as stub (empty) implementations."
what's the other method ?
You are close!
To prevent to pass touch event to superview, you should override all the methods for the touch events. Add all the touch event methods to your subview, then you should be OK.
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
- (void)touchesCancelled:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
