IOS navigationController.hidesBarsOnSwipe禁用了其他滑动

Question

在IOS 8中，它具有一项新功能，可在滑动时隐藏栏。所以我尝试了。但是，它禁用了我的其他滑动。代码是这样的：

self.navigationController.hidesBarsOnSwipe = YES;

// The follow code works if I comment out the above line
UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(backBarButtonItemPressed:)];
[swipe setDirection:UISwipeGestureRecognizerDirectionRight];
[swipe setNumberOfTouchesRequired:1];
[self.view addGestureRecognizer:swipe];
[self.webView.scrollView.panGestureRecognizer requireGestureRecognizerToFail:swipe];

有人有类似的问题吗？

Answer 1

 navigationController?.hidesBarsOnSwipe = true
 navigationController?.hidesBarsOnTap = true

Answer 2

在您的手势识别器上设置一个委托。即实施协议

UIGestureRecognizerDelegate

然后使用适当的方法，例如

gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:

确定两个手势识别器应如何协同工作。您可以通过

获得导航手势识别器

self.navigationController.barHideOnSwipeGestureRecognizer

Answer 3

实施UIGestureRecognizerDelegate

并覆盖以下方法：

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}
