當應用程序在一天內未處於活動狀態時，GCM推送通知不會在iPhone上顯示

在安裝應用程序後的iPhone/iPad上，應用程序能夠首次接收通知。一旦應用程序處於不活動狀態，它就會停止在前臺和後臺獲取通知。當應用程序在一天內未處於活動狀態時，GCM推送通知不會在iPhone上顯示

有人可以指出，我是我失蹤。從我第一次來看，看起來沒有消息格式的問題。

服務器代碼：

  message.put("priority", "high"); 
      message.put("content_available",true); 
      if (to != null) 
      { 
       message.put("to", to.replace("\\", "")); 
      } 
      if (messageId != null) 
      { 
       message.put("message_id", messageId); 
      } 
      JSONObject subobj = new JSONObject(); 
      subobj.put("sound", "default"); 
      message.put("notification", subobj); 

      message.put("data", payload); 
      if (timeToLive != null) 
      { 
       message.put("time_to_live", timeToLive); 
      } 
      if (delayWhileIdle != null && delayWhileIdle) 
      { 
       message.put("delay_while_idle", true); 
      } 
      if (collapseKey != null) 
      { 
       message.put("collapse_key", collapseKey); 
      } 
      message.put("delivery_receipt_requested", true);

客戶端代碼：

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

{

// First run Delete keychain 

if (![[NSUserDefaults standardUserDefaults] objectForKey:@"FirstRun"]) { 
    // Delete values from keychain here 

    application.applicationIconBadgeNumber = 0; 

    [self resetKeychain]; 
    [[NSUserDefaults standardUserDefaults] setValue:@"1strun" forKey:@"FirstRun"]; 
    [[NSUserDefaults standardUserDefaults] synchronize]; 
} 

self.viewController = [[MainViewController alloc] init]; 


CGRect screenBounds = [[UIScreen mainScreen] bounds]; 

#if __has_feature(objc_arc) 
    self.window = [[UIWindow alloc] initWithFrame:screenBounds]; 
#else 
    self.window = [[[UIWindow alloc] initWithFrame:screenBounds] 
autorelease]; 
#endif 
self.window.autoresizesSubviews = YES; 
//notification 

[self updateDurationLabel]; 
UIFont *font = [UIFont boldSystemFontOfSize:10.0f]; 
NSDictionary *attributes = [NSDictionary dictionaryWithObject:font forKey:NSFontAttributeName]; 
[self.segFromStyle setTitleTextAttributes:attributes forState:UIControlStateNormal]; 
[self.segToStyle setTitleTextAttributes:attributes forState:UIControlStateNormal]; 

[self flowManager]; 


UILocalNotification *remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
if (remoteNotification) { 
    application.applicationIconBadgeNumber = 0; 
    self.launchNotification = remoteNotification.userInfo; 

    NSLog(@"NotificationCheck: remoteNotification"); 

} 

UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]; 

if (localNotification) { 
    application.applicationIconBadgeNumber = 0; 
    NSLog(@"NotificationCheck: localNotification"); 

    self.launchNotification = localNotification.userInfo; 

    NSData* jsonData = [NSJSONSerialization dataWithJSONObject:localNotification.userInfo options:0 error:nil]; 
    NSString* jsonString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding]; 

    NSLog(@"Dict:%@", jsonString); 
     } 
[self.window makeKeyAndVisible]; 

return YES;

}

您可以使用此thread參考，其中它建議增加"priority": "high"給JSON在後臺獲取通知。

{ 
    "to" : "token...", 
    "priority": "high", 
    "notification" : { 
    "title": "GCM TITLE", 
    "body" : "FROM GCM", 
    "badge": "1", 
    "sound": "default" 
    } 
}

感謝響應。我確實已經設置了優先級和content_available標誌。 [message.put（「priority」，「high」）; message.put（「content_available」，true）;]只有在代碼中丟失的標誌是'徽章'，讓我試試它的運氣。 – leela
