iOS 6 UIGestures（Tap）停止使用QLPreviewController(iOS 6 UIGestures (Tap) stops working with QLPreviewController)

目前我在导航控制器中使用QLPreviewController。（pushViewController）

要隐藏导航栏，我使用UITapGestureRecognizer。用户可以通过单次触摸（点击）显示/隐藏导航栏。这在iOS5中运行良好

- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)]; [tapRecognizer setNumberOfTapsRequired:1]; [tapRecognizer setDelegate:self]; [[self view] addGestureRecognizer:tapRecognizer]; [tapRecognizer release]; } - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { return YES; } - (void)tapped:(UIGestureRecognizer*)gestureRecognizer { //hide -/- show navigation bar [[self navigationController] setNavigationBarHidden:![[[self navigationController] navigationBar] isHidden] animated:YES]; }

但是在发布的iOS 6版本中，水龙头现在完全被忽略了，所以我再也无法隐藏我的导航栏了。

我想隐藏导航栏的原因是什么？

如果您打开.numbers文档，导航栏会隐藏导航栏下的“工作表按钮”。

TY。

Currently I'm using a QLPreviewController in a navigation controller. (pushViewController)

To hide the navigationbar I use a UITapGestureRecognizer. The user can show/hide the navigation bar by a single touch (tap). This worked well in iOS5

- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)]; [tapRecognizer setNumberOfTapsRequired:1]; [tapRecognizer setDelegate:self]; [[self view] addGestureRecognizer:tapRecognizer]; [tapRecognizer release]; } - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { return YES; } - (void)tapped:(UIGestureRecognizer*)gestureRecognizer { //hide -/- show navigation bar [[self navigationController] setNavigationBarHidden:![[[self navigationController] navigationBar] isHidden] animated:YES]; }

But in the released version of iOS 6 the taps are now completely ignored, so I can't hide my navigation bar anymore.

Reason why I want to hide the navigation bar?

If you open a .numbers document, the navigationbar hides the 'sheet-buttons' under the navigation bar.
