在新的ios 5.1 UISplitViewController中，presentViewController:animated:completion显示问题 [英] presentViewController:animated:completion display issues in new ios 5.1 UISplitViewController

问题描述

使用UISplitViewController和presentViewController:animated:completion遇到了一些问题.

I've ran into some problems using UISplitViewController with presentViewController:animated:completion.

为了将问题分解为最简单的形式，我创建了一个带有master/detail模板的简单项目.在项目中，我在主视图的导航栏中添加了+按钮.加号按钮创建一个带有简单空白视图的导航控制器.然后使用presentViewController:animated:completion呈现此导航控制器.但是，显示的视图仅显示在主视图中，当您将其关闭时，主视图会占据整个屏幕.我似乎无法理解发生了什么.还有其他人遇到这个问题吗?这是代码.

To break the problem down into its simplest form, I've created a simple project with the master/detail template. In the project I've added a + button in the navigation bar of the master view. The plus button creates a navigation controller with a simple blank view. This navigation controller is then presented using presentViewController:animated:completion. However, the presented view only displays in the master view and when you dismiss it, the master view takes up the whole screen. I can't seem to understand what is going on. Anyone else encountered this problem? Here's the code.

- (void)showViewController:(id)sender
{
LMTestViewController *masterView = [[LMTestViewController alloc] init];
[self presentViewController:masterView animated:YES completion:nil];
[masterView release];
}

感谢您的帮助.

推荐答案

要模态显示，请使用窗口的根视图控制器.使用其他任何东西都会使事物在拆分视图中变得混乱，尤其是在旋转等情况下.

To present modally, use the window's root view controller. Using anything else will cause things to become confused in the split view, especially when rotating, etc.

[self.view.window.rootViewController presentViewController:masterView
                                                  animated:YES
                                                completion:NULL];
