iOS10之后注册推送，应用在前台也能显示通知栏，但不能在后台调用

        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionCarPlay) completionHandler:^(BOOL granted, NSError *_Nullable error) {
            if (!error) {
                NSLog(@"request authorization succeeded!");
            }
        }];

//  iOS 10: App在前台获取到通知
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
    // 根据APP需要，判断是否要提示用户Badge、Sound、Alert
    NSLog(@"willPresentNotification：%@", notification.request.content.userInfo);
    
        completionHandler(UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert);
    completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert);
    
}
// !!!:  iOS 10: 点击通知进入App时触发
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
}
        

iOS8之后注册推送，应用在前台不显示通知栏，但在后台也能被调用

 UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
    UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

//此方法在后台也能调用
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler NS_AVAILABLE_IOS(7_0)
{
    NSInteger state = [UIApplication sharedApplication].applicationState;

}
