Ios 注销后self.revealViewController对象为空

我已经实施了一个项目，我使用了

SWRevealViewController

，它工作正常，但当我使用下面的代码注销时

        dispatch_async(dispatch_get_main_queue(), ^{

            LoginViewController *loginView = \[self.storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"\];

            UINavigationController *navController = \[\[UINavigationController alloc\] initWithRootViewController:loginView\];

            \[UIApplication sharedApplication\].delegate.window.rootViewController = navController;

        });

       dispatch_async(dispatch_get_main_queue(), ^{

            UIStoryboard *storyboard = \[UIStoryboard storyboardWithName:@"Main" bundle:nil\];
            DashboardViewController *dashboardView = \[storyboard instantiateViewControllerWithIdentifier:@"DashboardViewController"\];
            \[self.navigationController pushViewController:dashboardView animated:YES\];
        });

它的注销成功，但当我再次登录使用以下代码

        dispatch_async(dispatch_get_main_queue(), ^{

            LoginViewController *loginView = \[self.storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"\];

            UINavigationController *navController = \[\[UINavigationController alloc\] initWithRootViewController:loginView\];

            \[UIApplication sharedApplication\].delegate.window.rootViewController = navController;

        });

       dispatch_async(dispatch_get_main_queue(), ^{

            UIStoryboard *storyboard = \[UIStoryboard storyboardWithName:@"Main" bundle:nil\];
            DashboardViewController *dashboardView = \[storyboard instantiateViewControllerWithIdentifier:@"DashboardViewController"\];
            \[self.navigationController pushViewController:dashboardView animated:YES\];
        });

其登录但侧菜单按钮不工作，因为

self.revealViewController

对象获取“

null

”。 有人能帮我解决这个问题吗

如果我没有弄错的话，您的rootViewController必须始终是revealViewController。如果您将其重置为其他内容，则不会获得revealController行为

如果您想恢复功能，必须将其设置回revealController。返回并查看如何设置revealController，并在登录方法中重新创建它
