How to detect a tap gesture using touchesBegan and touchesEnded - ios

Question

I've created a custom control which derives directly from a class UIView. Now I want to perform an action if a user tap on a particular part of my view. So I've overrided methods touchesBegan, touchesEnded and touchesCancelled. The problem is, that the method touchesEnded is never invoked, if I just tap on the display. The method touchesCancelled is called insted of it. touchesEnded is invoked only if I perform some gestures (swipe, move, ...).
Do I need to configure my view anyhow to enable tap gestures?
My code:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
NSLog(#"touchesBegan");
self->touchDown = YES;
[UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.value = 1.0;
} completion:nil];
}
- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
if (self->touchDown) {
NSLog(#"touchesEnded");
self->touchDown = NO;
[UIView animateWithDuration:0.3 animations:^{
self.value = 0.0;
} completion:nil];
}
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
if (self->touchDown) {
NSLog(#"touchesCancelled");
self->touchDown = NO;
[UIView animateWithDuration:0.3 animations:^{
self.value = 0.5;
} completion:nil];
}
}
For a tap gesture I get:

Answer 1

Have you tried to set recognizer.cancelsTouchesInView = NO; on your view
A Boolean value affecting whether touches are delivered to a view when a gesture is recognized.

Answer 2

You should go through this.
From Apple documentation,
https://developer.apple.com/documentation/uikit/uigesturerecognizer?changes=_4&language=objc
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
// Sent to the gesture recognizer when one or more fingers touch down in the associated view.
}
- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
//Sent to the gesture recognizer when one or more fingers move in the associated view.
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
//Sent to the gesture recognizer when one or more fingers lift from the associated view.
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
//Sent to the gesture recognizer when a system event (such as an incoming phone call) cancels a touch event.
}
