SplitViewコントローラーでマスタービューコントローラーを非表示および再表示する方法

XCode 4.2で新しい分割ビューベースのプロジェクトを作成しました

次にDetailViewController.mファイルこのメソッドを追加しました

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

   return NO;
}

これで、splitviewコントローラーの左右両方の部分を一度に表示できるようになりました。

これで、UIBarButtonItemナビゲーションバーにDetailViewControllerを追加しました。これを使用して、Portrairtモードとランドスケープモードの両方でマスタービューを非表示にしたり表示したりできます。

- (IBAction)hideUnhide:(id)sender 
{

//How can hide & unhide

}

これどうやってするの？

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

次を行う必要があります：

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

「setNeedsLayout」は、UISplitViewControllerに「shouldHideViewController」を要求させる

- (IBAction)hideUnhide:(id)sender  {
    UISplitViewController* spv = ...;

    self.hideMaster= !self.hideMaster;
    [ spv.view setNeedsLayout ]
}

IOS 5.1では、次のようにする必要があります。

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;
}

上記の応答を組み合わせて、IOS 6：

// 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;
}

IOS8ではこれは簡単です。

それを隠す

[UIView animateWithDuration:0.2 animations:^{
    splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
} completion:nil];

それを表示するには

[UIView animateWithDuration:0.2 animations:^{
    self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay;
} completion:nil];

デリゲートを再割り当てする必要がないというwzbozonのコメントに関して、私は2つの行が

self.splitViewController.delegate = nil;

self.splitViewController.delegate = self;

...シミュレーターでは必要ありませんでしたが、iOS5 iPad 1では必要でした。これらがないと、非表示/表示の動作は発生しませんでした（ボタンをクリックしてもマスタービューは折りたたまれません）。

displayModeButtonItemのUISplitViewControllerプロパティのアクションをトリガーすることにより、マスターViewControllerを表示/非表示にすることができます。

Swift

if let displayModeButtonItem = splitViewController?.displayModeButtonItem() {
    displayModeButtonItem.target?.performSelector(displayModeButtonItem.action)
}

Objective-C

UIBarButtonItem *displayModeButtonItem = [self.splitViewController displayModeButtonItem];
[displayModeButtonItem.target performSelector: displayModeButtonItem.action];

代理人、向き、レイアウトを同時にいじるよりも、自分にふさわしいと感じています。

さて、あなたの質問の簡単な部分は、ブール値を使用して、プロパティhideMasterを言うことです、そして次に

- (IBAction)hideUnhide:(id)sender 
{

   self.hideMaster= !self.hideMaster;

}

その後...

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

   return self.hideMaster;
}

これは正常に機能しますが、shouldHideViewControllerは、回転時など、splitVCの再描画中にのみ呼び出されるため、マスターは非表示/再表示のみを行います。

Swift 3.

私は使いました

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)

            }
        }
    }
