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

问题描述

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中效果很好

   - （void）viewWillAppear：（BOOL）animated {
 [super viewWillAppear中：动画]; 
 
 UITapGestureRecognizer * tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（tapped :)]; 
 [tapRecognizer setNumberOfTapsRequired：1]; 
 [tapRecognizer setDelegate：self]; 
 [[自我查看] 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，所以我无法隐藏导航栏。

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。

解决方案

因为ios 6 QLPreviewController实际上是一个完全独立的应用程序（单独的过程和所有内容）

Apple使用XPC：

=>所以当你推动它时，你的整个应用程序会移动到bg，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.

解决方案

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
