ios - 在解除父 View 时隐藏登录 uiViewController

Question

这是在我的应用程序中调用特定操作的普通 LoginView

sourceViewVontroller

if ([password length] == 0) {

     loginViewController *seatView = [mainStory instantiateViewControllerWithIdentifier:@"loggingView"];



    [self presentViewController:login animated:YES completion:nil];

}

它会检查用户在调用此操作时是否尚未登录，因此会将他重定向到 loginViewController，然后

登录 View Controller

UIStoryboard *mainStory = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

DestinationViewController *Dest = [mainStory instantiateViewControllerWithIdentifier:@"destView"];


[self presentViewController:Dest animated:YES completion:nil];

它转到需要登录的 destinationView，现在我的问题是如何返回(关闭不是 presentmodalView)到 sourceViewController，或者简单地说，如何在成功时从队列中删除 loginViewController 并直接关闭到源？

目标 View Controller

// Tried to use presentView .. but i dont need to reload sourceView, just dismiss to it !

//[self presentViewController:srcView animated:YES completion:NULL];

//This is what am doing ..

[self dismissViewControllerAnimated:NO completion:nil];

或者让我知道是否有其他专业的方式来执行此登录流程

Answer 1

我建议你另一种方式:

首先在 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

您将检查用户是否登录。如果登录，您将设置 rootView 为 destinationViewController。如果没有设置 rootView 为 loginViewController

示例代码:

UIStoryboard *mainStory = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
if (logged) {

   DestinationViewController *Dest = [mainStory instantiateViewControllerWithIdentifier:@"destView"];
self.window.rootViewController = Dest;
} else {
   LoginViewController *seatView = [mainStory instantiateViewControllerWithIdentifier:@"loggingView"];
   self.window.rootViewController = seatView;
}

注销时，你只需调用notification 或delegate 将window 的rootViewController 设置为loginViewController.
