沒有響應

Question

SplitViewController委託方法我已經加入拆分視圖控制器的視圖控制器上，因爲這樣的：

rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; 
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; 

detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; 
rootViewController.detailViewController = detailViewController; 

splitViewController = [[UISplitViewController alloc] init]; 
splitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, detailViewController, nil]; 
splitViewController.delegate = detailViewController; 

[self.view addSubview:splitViewController.view]; 

但在DetailViewController限定的本方法不會被調用：

- (void)splitViewController: (UISplitViewController*)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem*)barButtonItem forPopoverController: (UIPopoverController*)pc 

如果我設置splitviewcontroller在window s，那麼這個方法被調用！ 有何建議？

Answer 1

因爲我知道splitViewController不能是任何其他視圖的子視圖，所以splitViewController必須始終是mainViewController。

Answer 2

請確保您的DetailViewController類實現UISplitViewControllerDelegate協議。
