當應用程序第一次啓動時調用didReceiveRemoteNotification

我已經實現了我的didReceiveRemoteNotification方法。它的工作原理是顯示一個視圖控制器和通過的通知數據。這隻適用於應用程序已經在前臺或它在後臺運行。但是，當應用程序未運行且用戶單擊通知時，應用程序將啓動，但看起來好像沒有收到通知。通知沒有寫入文本文件，並且viewcontroller沒有被推送。當應用程序第一次啓動時調用didReceiveRemoteNotification

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{ 
    if (application.applicationState == UIApplicationStateActive) 
    { 
     NSDictionary *apsInfo = [userInfo objectForKey:@"aps"]; 

     NSString *alertMsg = @""; 
     NSString *badge = @""; 
     NSString *sound = @""; 
     NSString *custom = @""; 

     if([apsInfo objectForKey:@"alert"] != NULL) 
     { 
      alertMsg = [apsInfo objectForKey:@"alert"]; 
     } 


     if([apsInfo objectForKey:@"badge"] != NULL) 
     { 
      badge = [apsInfo objectForKey:@"badge"]; 
     } 


     if([apsInfo objectForKey:@"sound"] != NULL) 
     { 
      sound = [apsInfo objectForKey:@"sound"]; 
     } 

     if([userInfo objectForKey:@"Type"] != NULL) 
     { 
      custom = [userInfo objectForKey:@"Type"]; 
     } 

     // Set your appending text. 
     NSString *textToAdd = [NSString stringWithFormat:@":%@", alertMsg]; 

     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     NSString *documentsDirectory = [paths objectAtIndex:0]; 
     NSString *fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory]; 
     NSString *fileContents = [[NSString alloc] initWithContentsOfFile:fileName usedEncoding:nil error:nil]; 

     NSString *textToFile; 

     if (fileContents == NULL) 
     { 
      textToFile = alertMsg; 
     } 

     // Here you append new text to the existing one 
     if (fileContents != NULL) 
     { 
      textToFile = [fileContents stringByAppendingString:textToAdd]; 
     } 

     // Here you save the updated text to that file 
     paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     documentsDirectory = [paths objectAtIndex:0]; 
     fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory]; 
     NSString *content = textToFile; 
     [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; 

     NSArray *fileData = [textToFile componentsSeparatedByString:@":"]; 

     NSMutableArray *tableDataFromFile; 
     tableDataFromFile = [[NSMutableArray alloc] init]; 

     int i = 0; 

     for (i = 1; i < [fileData count]; i++) 
     { 
      [tableDataFromFile addObject:fileData[i]]; 
     } 

     NotificationViewController *vc = [[NotificationViewController alloc] initWithNibName:@"NotificationViewController" bundle:nil]; 
     vc.tableData = tableDataFromFile; 

     UIViewController *root = self.mainNavController.topViewController; 
     NSArray *vcs = [NSArray arrayWithObjects:root, vc, nil]; 
     [self.mainNavController setViewControllers:vcs animated:YES]; 
    } 
     // app was already in the foreground 
    else 
    { 
     while (done == FALSE) 
     { 

     } 

     NSDictionary *apsInfo = [userInfo objectForKey:@"aps"]; 

     NSString *alertMsg = @""; 
     NSString *badge = @""; 
     NSString *sound = @""; 
     NSString *custom = @""; 

     if([apsInfo objectForKey:@"alert"] != NULL) 
     { 
      alertMsg = [apsInfo objectForKey:@"alert"]; 
     } 


     if([apsInfo objectForKey:@"badge"] != NULL) 
     { 
      badge = [apsInfo objectForKey:@"badge"]; 
     } 


     if([apsInfo objectForKey:@"sound"] != NULL) 
     { 
      sound = [apsInfo objectForKey:@"sound"]; 
     } 

     if([userInfo objectForKey:@"Type"] != NULL) 
     { 
      custom = [userInfo objectForKey:@"Type"]; 
     } 

     // Set your appending text. 
     NSString *textToAdd = [NSString stringWithFormat:@":%@", alertMsg]; 

     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     NSString *documentsDirectory = [paths objectAtIndex:0]; 
     NSString *fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory]; 
     NSString *fileContents = [[NSString alloc] initWithContentsOfFile:fileName usedEncoding:nil error:nil]; 

     NSString *textToFile; 

     if (fileContents == NULL) 
     { 
      textToFile = alertMsg; 
     } 

     // Here you append new text to the existing one 
     if (fileContents != NULL) 
     { 
      textToFile = [fileContents stringByAppendingString:textToAdd]; 
     } 

     // Here you save the updated text to that file 
     paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     documentsDirectory = [paths objectAtIndex:0]; 
     fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory]; 
     NSString *content = textToFile; 
     [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; 

     NSArray *fileData = [textToFile componentsSeparatedByString:@":"]; 

     NSMutableArray *tableDataFromFile; 
     tableDataFromFile = [[NSMutableArray alloc] init]; 

     int i = 0; 

     for (i = 1; i < [fileData count]; i++) 
     { 
      [tableDataFromFile addObject:fileData[i]]; 
     } 

     NotificationViewController *vc = [[NotificationViewController alloc] initWithNibName:@"NotificationViewController" bundle:nil]; 
     vc.tableData = tableDataFromFile; 

     UIViewController *root = self.mainNavController.topViewController; 
     NSArray *vcs = [NSArray arrayWithObjects:root, vc, nil]; 
     [self.mainNavController setViewControllers:vcs animated:YES]; 

    } 
      // app was just brought from background to foreground 


}

有人能幫我解決這個問題嗎？一旦didFinishLaunchingWithOptions完成，布爾值done就設置爲true。我只想讓notificationviewcontroller打開並顯示通知，如果在應用程序根本沒有運行時按下通知。

您應該添加這樣的事情代碼：

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

     NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey]; 

     //Accept push notification when app is not open 
     if (remoteNotif) {  
      [self handleRemoteNotification:application userInfo:remoteNotif]; 
      return YES; 
     } 

     return YES; 
    }

您可以從didReceiveRemoteNotification移動邏輯一些常見功能，並調用該函數，從兩個地方。這僅在用戶通過點擊通知來打開應用程序時纔有效。如果用戶通過點擊應用程序圖標打開應用程序，通知數據將不會到達該應用程序。

謝謝！這工作完美。是的，將邏輯從didReceiveRemoteNotification移動到另一個方法會更好，因爲它會使代碼更短。 – 2013-02-20 14:37:12

不客氣！ – Eran 2013-02-21 02:14:22

@Eran你能提供swift代碼嗎？ – vinbhai4u 2015-07-07 14:54:53

Swift代碼

let remoteNotif: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] 

      //Accept push notification when app is not open 
      if ((remoteNotif) != nil) { 

       self.handleRemoteNotification(remoteNotif!) 
      } 


func handleRemoteNotification(remoteNotif: AnyObject?){ 
//handle your notification here 
}

@Eran謝謝:)
