在非模态时，展开segue不会忽略自适应弹出窗口 [英] Unwind segue doesn't dismiss adaptive popover presentation when not modal

问题描述

iOS 9测试版的更新：Apple可能已针对iOS 9解决此问题。如果您针对iOS 8解决此问题，请确保它在iOS 9上也能正常运行。

在故事板中，我创建了一个popover演示文件segue，用于从按钮呈现导航和视图控制器，以及创建展开segue。

In storyboard, I've created a popover presentation segue to present a navigation and view controller from a button, as well as creating an unwind segue.

在纵向方向上，模态（全屏）演示文稿按预期展开/解除。

In portrait orientation, the modal (fullscreen) presentation is unwound/dismissed, as expected.

在横向方向，展开segue也会获得但是，popover演示文稿是而不是自动被解雇。

In landscape orientation, the unwind segue also gets called, however the popover presentation is not automatically dismissed.

我是否错过了挂钩的东西？我是否必须自行解除popover演示文稿？

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)__unused sender
{
    if ([[segue identifier] isEqualToString:@"showSelectBookChapter"])
    {
        UINavigationController *navigationController = segue.destinationViewController;

        if ([navigationController.topViewController isKindOfClass:[BIBLESelectViewController class]])
        {
            BIBLESelectViewController *selectViewController = (BIBLESelectViewController *)navigationController.topViewController;
            selectViewController.initialBookChapterVerse = self.bookChapterVerse;
        }
    }
}

- (IBAction)unwindToBIBLEChapterViewController:(UIStoryboardSegue *)segue
{
    if ([segue.identifier isEqualToString:@"unwindToBIBLEChapterViewController"]) {
        if ([segue.sourceViewController isKindOfClass:[BIBLESelectViewController class]])
        {
            BIBLESelectViewController *sourceViewController = (BIBLESelectViewController *)segue.sourceViewController;
            self.bookChapterVerse = sourceViewController.selectedBookChapterVerse;
            [self.tableView reloadData];

        }
    }
}

更新：
查看gabbler的样本后代码，我已经将问题缩小到popover在单视图应用程序中解雇罚款，但不在主细节应用程序中解决。

Update: After looking at gabbler's sample code, I've narrowed the problem down to popover dismissing fine in a Single View Application, but not in a Master-Detail Application.

更新2：
以下是层次结构的样子（为简单起见省略了导航控制器），回答了Luis问的问题：

Update 2: Here's what the hierarchy looks like (omitting navigation controllers for simplicity's sake), in answer to the question Luis asked:

• 拆分视图控制器
  
  
  
  
  • 主视图控制器
  
  
  • 详细视图控制器
    
    
    
    
    • 章节视图控制器（模态页面表）
      
      
      
      
      • 选择视图控制器（解开章节视图控制器的有问题的弹出窗口，但不是'解雇）
      
      

      正如我之前提到的那样pdate，我创建了一个新的主/详细模板，并直接从详细视图中的（按钮）中显示一个弹出窗口。它不会被解雇。

      As I mentioned in the previous update, I created an new master/detail template, and simply presented a popover directly from (a button in) the detail view. It won't dismiss.

      推荐答案

      我也遇到了这个问题。我从主视图控制器（UISplitViewController）以模态方式（作为表单）呈现视图控制器。这个问题只发生在iPad上（也可能是横向模式下的iPhone 6+，但我没有检查）。我最终在我的展开动作方法（使用Swift）中执行以下操作，并且它运行良好。

      I ran into this problem too. I present a View Controller modally (as a form sheet), from the Master View Controller (UISplitViewController). The problem only occurred on the iPad (probably the iPhone 6+ in landscape mode too, but I didn't check it). I ended up doing the following in my unwind action method (using Swift), and it works good.

      if !segue.sourceViewController.isBeingDismissed() {
          segue.sourceViewController.dismissViewControllerAnimated(true, completion: nil)
      }
