Question

SplitViewController委托方法我已经加入拆分视图控制器的视图控制器上，因为这样的：

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限定的本方法不会被调用：

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

如果我设置splitviewcontroller在window s，那么这个方法被调用！ 有何建议？

Answer 1

因为我知道splitViewController不能是任何其他视图的子视图，所以splitViewController必须始终是mainViewController。

Answer 2

请确保您的DetailViewController类实现UISplitViewControllerDelegate协议。
