如何隐藏&在SplitView控制器中取消隐藏主视图控制器 [英] How to hide & unhide Master View Controller in SplitView Controller

问题描述

我在我的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显示左和右我的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<$ c $中添加了 UIBarButtonItem c> DetailViewController 导航栏，我想通过使用哪些我可以隐藏&在Portrairt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;

您需要做的下一步：

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