我有一个页面视图控制器,其中显示了五个视图控制器。
我尝试添加这些滑动手势但是没有被调用?
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];
为什么这些被触发,我该怎么办呢?我的目标是检测用户滑动页面视图控制器的方向。

向self.view添加手势
[self.view addGestureRecognizer:swipeGestureRight];
我希望它会起作用

试试这个
设置UIGestureRecognizer
和
实施shouldRecognizeSimultaneouslyWithGestureRecognizer
:
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
实施shouldReceiveTouch
:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
return YES;
}
希望这会有所帮助。如果你仍然面临这个问题,请告诉我。
