我在XCode 4.2中创建了一个新的基于拆分视图的项目
然后在DetailViewController.m文件中添加了此方法
- (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。
现在我在我的UIBarButtonItem导航栏中添加了DetailViewController，我想通过使用哪个我可以隐藏＆amp;在Portrairt和Landscape Mode中展示我的Master View。
- (IBAction)hideUnhide:(id)sender
{
//How can hide & unhide
}
我该怎么做？

instead spv.delegate=nil; spv.delegate=self;
你需要做下一步：
[spv willRotateToInterfaceOrientation:self.interfaceOrientation duration:0];

'setNeedsLayout'使UISplitViewController要求“shouldHideViewController”
- (IBAction)hideUnhide:(id)sender {
UISplitViewController* spv = ...;
self.hideMaster= !self.hideMaster;
[ spv.view setNeedsLayout ]
}

在iOS 5.1中，您必须这样做：
内部DetailViewController.m
- (IBAction)hideUnhide:(id)sender {
UISplitViewController* spv = ...;
self.hideMaster= !self.hideMaster;
[spv.view setNeedsLayout];
spv.delegate = nil;
spv.delegate = self;
}
- (BOOL)splitViewController:(UISplitViewController*)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation {
return self.hideMaster;
}
答案 3 :(得分：4)
我结合了以上回答，以下内容在IOS 6中运作良好：
// In split delegate
-(void)hideMaster:(BOOL)hideState
{
_masterIsHidden = hideState;
[self.splitViewController.view setNeedsLayout];
self.splitViewController.delegate = nil;
self.splitViewController.delegate = self;
[self.splitViewController willRotateToInterfaceOrientation:[UIApplication sharedApplication].statusBarOrientation duration:0];
}
-(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
return self.masterIsHidden;
}

[self.tabBarController.tabBar setHidden:NO];
[self hideMaster:NO];

-(void)hideMaster:(BOOL)hideState

关于wzbozon关于不需要重新分配代表的评论，我发现这两行
self.splitViewController.delegate = nil;
self.splitViewController.delegate = self;
...在模拟器上不需要，但在我的iOS5 iPad上需要1.没有它们，没有发生隐藏/显示行为（点击按钮没有折叠主视图）。
答案 6 :(得分：1)
在iOS8中，这很容易。
隐藏它
class CustomView: NSView {
@IBOutlet weak var view: NSView!
@IBOutlet weak var textField: NSTextField!
required init(coder: NSCoder) {
super.init(coder: coder)!
let frameworkBundle = Bundle(for: classForCoder)
assert(frameworkBundle.loadNibNamed("CustomView", owner: self, topLevelObjects: nil))
addSubview(view)
}
显示
[UIView animateWithDuration:0.2 animations:^{
splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
} completion:nil];
答案 7 :(得分：0)
嗯，问题的简单部分是使用bool，比如属性hideMaster，然后
- (IBAction)hideUnhide:(id)sender
{
self.hideMaster= !self.hideMaster;
}
然后......
- (BOOL)splitViewController: (UISplitViewController*)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
//This method is only available in iOS5
return self.hideMaster;
}
这样可以正常工作，但是只在重新绘制splitVC期间调用了shouldHideViewController，例如在旋转期间，所以master只隐藏/取消隐藏。

您可以通过触发displayModeButtonItem的{{1}}属性的操作来显示/隐藏主ViewController：
夫特
UISplitViewController目标-C
if let displayModeButtonItem = splitViewController?.displayModeButtonItem() {
displayModeButtonItem.target?.performSelector(displayModeButtonItem.action)
}
对我来说，比同时干预代表，方向和布局更合适。

SWIFT 3.0
我已经
了override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showDetail" {
if let indexPath = self.tableView.indexPathForSelectedRow {
let object = self.exercises[indexPath.row]
let controller = (segue.destination as! UINavigationController).topViewController as! DetailViewController
controller.detailItem = object
controller.navigationItem.leftBarButtonItem = self.splitViewController?.displayModeButtonItem
controller.navigationItem.leftItemsSupplementBackButton = true
UIView.animate(withDuration: 0.2, delay: 0.0, options: [.curveEaseOut], animations: {
self.splitViewController?.preferredDisplayMode = .primaryHidden
}, completion: nil)
}
