如何隐藏&在 SplitView 控制器中取消隐藏主视

How to hide amp; unhide Master View Controller in SplitView Controller(如何隐藏amp;在 SplitView 控制器中取消隐藏主视图控制器)

问题描述

我在 XCode 4.2 中创建了一个新的基于拆分视图的项目

I have created a new split view based project in my XCode 4.2

然后在 DetailViewController.m 文件中我添加了这个方法

Then in DetailViewController.m file i have add this method

- (BOOL)splitViewController: (UISplitViewController*)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation 
{
  //This method is only available in iOS5  

   return NO;
}

现在通过这样做，我可以同时显示 left &我的 splitview 控制器的右侧部分.

Now by doing this i can able to show both left & right part of my splitview Controller at a time.

现在我在我的 DetailViewController 导航栏中添加了一个 UIBarButtonItem，我想通过使用它来隐藏 &在纵向和横向模式下显示我的主视图.

Now i have added a UIBarButtonItem in my DetailViewController Navigation bar and i want by using which i can hide & show my Master View both in Portrairt and Landscape Mode.

- (IBAction)hideUnhide:(id)sender 
{

//How can hide & unhide

}

我该怎么做?

推荐答案

instead spv.delegate=nil; spv.delegate=self;

接下来你需要做的:

[spv willRotateToInterfaceOrientation:self.interfaceOrientation duration:0];
