I have a page view controller with five view controllers that get displayed.
I have tried adding these swipe gestures but they are not getting called?
UISwipeGestureRecognizer *swipeGestureRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe:)];
swipeGestureRight.numberOfTouchesRequired = 1;
swipeGestureRight.direction = (UISwipeGestureRecognizerDirectionRight);
[self.scrollView addGestureRecognizer:swipeGestureRight];
UISwipeGestureRecognizer *swipeGestureLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe:)];
swipeGestureLeft.numberOfTouchesRequired = 1;
swipeGestureLeft.direction = (UISwipeGestureRecognizerDirectionLeft);
[self.scrollView addGestureRecognizer:swipeGestureLeft];
Why arn't these being triggered and what can I do about it? My goal is to detect what direction the user swipes the page view controller.
add gesture to self.view
[self.view addGestureRecognizer:swipeGestureRight];
I hope it will work
Try this
Set the delegate of your UIGestureRecognizer
and
Implement shouldRecognizeSimultaneouslyWithGestureRecognizer
:
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{ return YES; }
Implement shouldReceiveTouch
:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { return YES; }
Hope this helps. Let me know if you still face the issue.
