从SplitViewController中的DetailViewController隐藏MasterViewController

Question

我有一个SplitViewController设置DetailViewController和MasterViewController。 DetailViewController包含一个地图，我想在地图上放置一个按钮，用于折叠和展开MasterViewController。就像这在苹果的App Store应用：按钮

点击然后给出：

我如何能达到类似的效果任何想法？注意我不想关闭顶级工具栏，只需要MasterViewController。谢谢！

SOLUTION

感谢普拉，我在IBAction为最终的解决方案是：

if (self.splitViewController.preferredDisplayMode == UISplitViewControllerDisplayModePrimaryHidden) { 
    self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible; 
} else { 
    self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden; 
} 

[UIView animateWithDuration:0.5 animations:^ { 
    [self.splitViewController.view layoutIfNeeded]; 
}];

隐藏主视图

AppDelegate * appDelegateObj = (AppDelegate *)[UIApplication sharedApplication].delegate; 
     UISplitViewController * splitView = appDelegateObj.splitViewObj; 
     splitView.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden; 
     [UIView animateWithDuration:1.0 animations:^ 
     { 
      [spv.view layoutIfNeeded]; 
     }]; 

show master view 


AppDelegate * appDelegateObj = (AppDelegate *)[UIApplication sharedApplication].delegate; 
     UISplitViewController * splitView = appDelegateObj.splitViewObj; 
     splitView.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible; 
     [UIView animateWithDuration:1.0 animations:^ 
     { 
      [spv.view layoutIfNeeded]; 
     }];
