提问by user1041614
Im using a splitViewController on my iPad app but before that, i have a login and when authenticated successfully I refresh the root and detail view. The problem is that once i load the mainview nothing happens, i try by pushing any views and there is no events.
我在我的 iPad 应用程序上使用了 splitViewController，但在此之前，我有一个登录名，成功通过身份验证后，我刷新了根视图和详细信息视图。问题是，一旦我加载了主视图，就什么也没有发生，我尝试推送任何视图并且没有事件。
And while I load the Login view modally I get this error: "Unbalanced calls to begin/end appearance transitions for
当我以模态加载登录视图时，我收到此错误：“对开始/结束外观转换的不平衡调用
i do the login view in the mainview (frontViewController) by using this:
我使用以下方法在主视图（frontViewController）中执行登录视图：
-(void)displayLoginView:(BOOL)animated{
LoginView *loginController = [[LoginView alloc] initWithNibName:@"LoginView" bundle:nil];
[self presentModalViewController:loginController animated:YES];
}
}
- (void)viewDidLoad{
[super viewDidLoad];
//Add logout button
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStyleBordered target:self action:@selector(logout)]; //If not already logged in, display login view [self displayLoginView:NO]; }
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStyleBordered target:self action:@selector(logout)]; //如果还没有登录，则显示登录视图[self displayLoginView:NO]; }
-(void)logout{
[self displayLoginView:YES];
}
}
and appdelegate.m :
和 appdelegate.m ：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
FrontViewController *frontViewController;
RearViewController *rearViewController;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
frontViewController = [[FrontViewController alloc] initWithNibName:@"FrontViewController_iPhone" bundle:nil];
rearViewController = [[RearViewController alloc] initWithNibName:@"RearViewController_iPhone" bundle:nil];
}
else{
frontViewController = [[FrontViewController alloc] initWithNibName:@"FrontViewController_iPad" bundle:nil];
rearViewController = [[RearViewController alloc] initWithNibName:@"RearViewController_iPad" bundle:nil];
}
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:frontViewController];
RevealController *revealController = [[RevealController alloc] initWithFrontViewController:navigationController rearViewController:rearViewController];
self.viewController = revealController;
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
}

Check your viewWillAppear:animated:, viewDidAppear:animated:, viewWillDisappear:animated:, and viewDidDisappear:animated:methods, either you dont implement them or you have to call the [super viewDid....].
I had the same pb, the cause was shouldAutoRotateToInterfaceOrientation : one of them was returning false whereas the others were returning true, I set them to return the same an It was ok.
检查你的viewWillAppear:animated:, viewDidAppear:animated:, viewWillDisappear:animated:, and viewDidDisappear:animated:方法，要么你没有实现它们，要么你必须调用 [super viewDid....]。我有相同的 pb，原因是 shouldAutoRotateToInterfaceOrientation ：其中一个返回 false 而其他返回 true，我将它们设置为返回相同的，没关系。
