要显示一个FirstViewController在调用iPhone中的SecondViewController的方法

Question

其实我正在制作一个闹钟应用程序。在那当我设置时间UILocalNotification事件发生在那个时候，它调用AppDelegate类即didReceiveNotifications方法的方法。在这个方法中，我写了一个代码来调用SetViewController（showReminder方法）的一个方法，现在在这个方法中，我希望它应该显示一个NewViewController，即TimeViewController，因为我必须在警报调用时显示动画。

我需要这个当Alarm被调用时，我已经设置了一个动作表来显示，但我想显示动画also.Action表单出现在所有视图但动画可以只显示在特定的视图，这就是为什么我需要显示一个不同的ViewController。

这里是我想做的代码： - ？我已经尝试了这些人也喜欢PresentModalViewController，dismissModalViewController，AddSubview ，删除的SuperView ......但结果都是阴性:(我应该怎么办..

几乎整个代码： -

AppDelegate类： -

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { 
    if (notification){ 
     NSLog(@"In did Notification"); 
     NSString *reminderText = [notification.userInfo objectForKey:kRemindMeNotificationDataKey]; 
     [viewController showReminder:reminderText]; 
     application.applicationIconBadgeNumber = 0; 
    } 
} 

setViewController.h： -

Answer 1

你的viewController可能会显示该视图，但如果没有SetViewController的视图，屏幕上就看不到它。你将不得不先去SetViewController，然后展示你的TimeViewController。这是对的，你想显示SetViewController，但立即调用showReminder：方法？但仅限于didReceiveLocalNotification :.

如果是这种情况，设置一个标志，并在SetViewControllers text属性.H，

BOOL isFromNotification; 
NSString *notifText; 

并呈现SetViewController，并设置标志

SetViewController *setViewController = [SetViewController alloc]........ 
setViewController.isFromNotification = YES; 
setViewController.notifText = reminderText; 
[self presentModalViewController animated:YES} 

，然后在viewDidAppear：SetViewController

if(isFromNotification = YES){ 
    [self showReminders:notifText]; 
} 

Answer 2

如果我有你的权利，

后，你想显示在新视图的动画，然后显示动作片的通知？

现在你的appdelegate

[viewController showReminder:reminderText]; 

调用它的方式应该是self.viewcontroller或_viewcontroller的实际上是保留对象

在showreminder你叫

动画，这本身添加一个子视图，顺便说一句，就是在同一个线程中运行，即以串行方式运行。 ，然后再次将viewcontroller添加为子视图。 ，然后尝试将操作表从父级添加到子视图（viewcontroller），而操作表应该可能在viewcontroller本身中。

我知道了吗？

如上所述，不确定什么事情会崩溃，可能出现在几个领域。

我想： 确保您拨打通过有效的指针保留的对象（使用自例如） 有一个视图控制器，你目前模式为显示在一个单独的线程（performselectoronthread）动画子视图和对actionsheet那。 然后如果你需要打电话给家长，你设置了一个委托或者你做的丑陋的方式。

self.yourviewcontroller.myParentObj = self 

即设置yourviewcontroller指针上分的ViewController，然后你就可以公开呼吁像

[self.myParentObj whatevermethod_you_have_in_parent]; 

不过话又说回来我写这篇文章，从我的头顶..
