Question

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，并且在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，一旦我加载主视图没有任何反应，我尝试推送任何视图，没有事件。

当我以模态方式加载Login视图时，我收到此错误：“不平衡调用开始/结束外观转换

我使用以下命令在主视图（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）]; //如果尚未登录，请显示登录视图 [self displayLoginView：NO]; }

-(void)logout{
[self displayLoginView:YES];

}

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;

}

有人可以帮助我吗？

提前多多感谢！

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而其他人返回true，我设置它们返回相同的一个它没关系。
