iOS 6 UIGestures (Tap) 停止使用 QLPreviewController

问题描述

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

为了隐藏导航栏，我使用了 UITapGestureRecognizer.用户可以通过单击(点击)显示/隐藏导航栏.这在 iOS5 中运行良好

- (void)viewWillAppear:(BOOL)animated {[超级viewWillAppear:动画]；UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];[tapRecognizer setNumberOfTapsRequired:1];[tapRecognizer setDelegate:self];[[自拍] addGestureRecognizer:tapRecognizer];[tapRecognizer 发布]；}- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {返回是；}- (void)tapped:(UIGestureRecognizer*)gestureRecognizer{//隐藏 -/- 显示导航栏[[self navigationController] setNavigationBarHidden:![[[self navigationController] navigationBar] isHidden] animated:YES];}

但是在 iOS 6 的发布版本中，现在完全忽略了点击，所以我不能再隐藏我的导航栏了.

为什么要隐藏导航栏?

如果您打开 .numbers 文档，导航栏会隐藏导航栏下方的工作表按钮".

从 ios 6 开始，QLPreviewController 实际上是一个完全独立的应用程序(独立的进程和一切)

Apple 为此使用 XPC:

=> 所以当你推送它时，你的整个应用都会移动到背景，包括它的窗口和手势识别器

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.

since ios 6 the QLPreviewController is actually a completely seperate app (seperate process and everything)

Apple uses XPC for that:

• http://oleb.net/blog/2012/10/remote-view-controllers-in-ios-6/

• https://twitter.com/eldudi/statuses/253438028163457024

=> so when you push that, your whole app moves to the bg, including its window and gesture recognizers
