要顯示一個FirstViewController在調用iPhone中的SecondViewController的方法

Question

其實我正在製作一個鬧鐘應用程序。在那當我設置時間UILocalNotification事件發生在那個時候，它調用AppDelegate類即didReceiveNotifications方法的方法。在這個方法中，我寫了一個代碼來調用SetViewController（showReminder方法）的一個方法，現在在這個方法中，我希望它應該顯示一個NewViewController，即TimeViewController，因爲我必須在警報調用時顯示動畫。

我需要這個當Alarm被調用時，我已經設置了一個動作表來顯示，但我想顯示動畫also.Action表單出現在所有視圖但動畫可以只顯示在特定的視圖，這就是爲什麼我需要顯示一個不同的ViewController。

這裏是我想做的代碼： - ？我已經嘗試了這些人也喜歡PresentModalViewController，dismissModalViewController，AddSubview ，刪除的SuperView ......但結果都是陰性:(我應該怎麼辦..

幾乎整個代碼： -

AppDelegate類： -

- (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; 
    } 
}

Answer 1

你的viewController可能會顯示該視圖，但如果沒有SetViewController的視圖，屏幕上就看不到它。你將不得不先去SetViewController，然後展示你的TimeViewController。這是對的，你想顯示SetViewController，但立即調用showReminder：方法？但僅限於didReceiveLocalNotification :.

如果是這種情況，設置一個標誌，並在SetViewControllers text屬性.H，

BOOL isFromNotification; 
NSString *notifText; 

並呈現SetViewController，並設置標誌

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

，然後在viewDidAppear：SetViewController

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

Answer 2

如果我有你的權利，

後，你想顯示在新視圖的動畫，然後顯示動作片的通知？

現在你的appdelegate

[viewController showReminder:reminderText]; 

調用它的方式應該是self.viewcontroller或_viewcontroller的實際上是保留對象

在showreminder你叫

動畫，這本身添加一個子視圖，順便說一句，就是在同一個線程中運行，即以串行方式運行。 ，然後再次將viewcontroller添加爲子視圖。 ，然後嘗試將操作表從父級添加到子視圖（viewcontroller），而操作表應該可能在viewcontroller本身中。

我知道了嗎？

如上所述，不確定什麼事情會崩潰，可能出現在幾個領域。

我想： 確保您撥打通過有效的指針保留的對象（使用自例如） 有一個視圖控制器，你目前模式爲顯示在一個單獨的線程（performselectoronthread）動畫子視圖和對actionsheet那。 然後如果你需要打電話給家長，你設置了一個委託或者你做的醜陋的方式。

self.yourviewcontroller.myParentObj = self 

即設置yourviewcontroller指針上分的ViewController，然後你就可以公開呼籲像

[self.myParentObj whatevermethod_you_have_in_parent]; 

不過話又說回來我寫這篇文章，從我的頭頂..
