iOS8.2-app在后台运行时，不会收到任何推送通知，
而如果它在前台运行，它可以很好地接收推送通知。
知道发生了什么事吗？
运行于CloudKit Development模式，订阅用于添加、编辑和删除，并使用以下内容didReceiveRemoteNotification:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSLog(@"Push received.");
NSDictionary * apsDict = [userInfo objectForKey:@"aps"];
NSString * alertText = [apsDict objectForKey:@"alert"];
//TODO: get the record information from the notification and create the appropriate message string.
if(application.applicationState == UIApplicationStateActive) {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Notification" message:alertText delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];
[alert show];
} else {
if([application currentUserNotificationSettings].types & UIUserNotificationTypeAlert) {
UILocalNotification * localNotification = [[UILocalNotification alloc] init];
localNotification.alertBody = NSLocalizedString(@"alert body", nil);;
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:2];
[application presentLocalNotificationNow:localNotification];
}
}
completionHandler(UIBackgroundFetchResultNoData);
}
当您进入应用程序设置功能时，是否为后台模式启用了远程通知？
See this screenshot:
除此之外，您是否注册了所有通知类型，如下所示：
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert | .Badge | .Sound, categories: nil))
application.registerForRemoteNotifications()
在您的订阅中，您是否为 CKNotificationInfo 发送alertBody 或alertLocalizationKey？如果您这样做，那么您将已经从操作系统收到通知，并且无需设置本地通知。
更新：正如下面Porton提到的，这个问题通过填写alertBody解决了。
