當應用程序未運行時處理推送通知（即完全死亡）

Question

我可以將推送通知發送到我的IOS設備。但是當我點擊該通知時，它只是打開應用程序。應用程序內沒有顯示任何消息。由我使用

代碼：

if (application.applicationState == UIApplicationStateActive) { 

    NSString *cancelTitle = @"Close"; 

    NSString *showTitle = @"Show"; 

    NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Some title" 

                 message:message 

                 delegate:self 

               cancelButtonTitle:cancelTitle 

               otherButtonTitles:showTitle, nil]; 

    [alertView show]; 

    [alertView release]; 

} else { 

    //Do stuff that you would do if the application was not active 

} 

但無法顯示我的消息，以上代碼的幫助。上述代碼僅適用於我的應用程序處於前臺狀態的情況下打開，而不是僅此警報纔會顯示。

請幫忙。

謝謝。

處理這種事情的最好方法是在APN中使用深度鏈接。這將讓您嵌入數據，然後可以在您的應用程序中處理數據，並將用戶引導至特定事件。

否則，您僅限於使用應用程序委託中的ApplicationDidEnterForeground方法。只要把你的alertView代碼放在那裏，任何時候你的應用程序都會被放到前臺運行。

從蘋果文檔

https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/Introduction.html

「當你的應用程序必須啓動以 收到通知，UIKit中包括推出 UIApplicationLaunchOptionsLocalNotificationKey或 UIApplicationLaunchOptionsRemoteNotificationKey關鍵 選項字典傳遞給你的應用程序代理的 應用程序：willFinishLaunchingWithOptions：和 應用程序：didFinishLaunchingWithOptio ns：方法。 這些密鑰的存在讓你知道，有通知數據等待 處理，並讓你有機會適當地配置你的應用程序的界面 。不過，您不需要在這些 方法中處理通知。在您的應用運行後，UIKit會調用您的應用委託的其他方法 ，例如 應用：didReceiveLocalNotification：方法，以便爲您提供處理通知數據的 機會。這方法被稱爲 取決於哪些方法您實現與用戶 是否與該消息的系統UI交互。」

所以，請檢查您的應用程序已經啓動，由於通知，如果是這樣顯示的對話框

我認爲有一個簡單的解決方案。

1. 可以存儲一些標誌的應用程序，一旦當您收到 通知，您可以檢查該怎麼辦呢here
2. 後，關於你當你從後臺 也許像here
檢測

如果你想，當你從通知打開應用程序，只顯示警報，那麼也許你這是你solution

當應用程序未運行（或完全死亡）時處理推送通知

我發佈此解決方案，因爲它爲我工作。

轉到您的AppDelegate.m文件。

步驟1： 寫入這個函數內的代碼：

-(BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions 
{ 

    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 

if (localNotif) { 

     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[localNotif valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 


    } 

} 

步驟2：

插入該全碼：

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{ 

NSLog(@"%s..userInfo=%@",__FUNCTION__,userInfo); 

/** 
    * Dump your code here according to your requirement after receiving push 
    */ 

    if (application.applicationState == UIApplicationStateActive) { 
     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 

    else if(application.applicationState == UIApplicationStateBackground){ 

     //app is in background, if content-available key of your notification is set to 1, poll to your backend to retrieve data and update your interface here 


     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 


    else if(application.applicationState == UIApplicationStateInactive){ 

     //app is in background, if content-available key of your notification is set to 1, poll to your backend to retrieve data and update your interface here 


     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 


} 

這整個代碼將工作，無論是應用程序有效，無效或完全死亡。它會爲您提供推送消息的AlertView。

當應用程序被完全殺死GET通知代碼

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
if (launchOptions != nil) 
{ 
    //opened from a push notification when the app is closed 
    NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
    if (userInfo != nil) 
    { 
     NSLog(@"userInfo->%@",[userInfo objectForKey:@"aps"]); 
     //write you push handle code here 

    } 

} 
}
