Ios 当我收到通知时，在UITableView中添加新行的代码放在哪里？

我试图做的是将我从收到的通知中获得的信息放到UITableView中。我已经做到了，但是它只更新了第一行。也就是说，如果我向我的应用程序发送两个连续的通知，我将只看到第二个通知信息，因为它会覆盖第一个通知信息

如何添加另一行以包含通知数据？ 我曾经配置推送通知

AppDelegate.m

：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [Pushbots sharedInstanceWithAppId:@"--My App ID--"];
    [[Pushbots sharedInstance] receivedPush:launchOptions];
    return YES;
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // This method will be called everytime you open the app
    // Register the deviceToken on Pushbots
    [[Pushbots sharedInstance] registerOnPushbots:deviceToken];
}
-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
    NSLog(@"Notification Registration Error %@", [error userInfo]);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    //Handle notification when the user click it while app is running in background or foreground.
    [[Pushbots sharedInstance] receivedPush:userInfo];
    // you can get the required message as below
    NSLog(@"UserInfo: %@", userInfo);
    NSString *msg = [userInfo valueForKey:@"aps"];
    NSString *alertMsg = [msg valueForKey:@"alert"];
    NSLog(@"Push Notification:%@",alertMsg);

    [[NSUserDefaults standardUserDefaults]setObject:alertMsg forKey:@"ReceivedNotifications"];
    NSLog(@"Alert: %@", alertMsg);

    [[NSNotificationCenter defaultCenter]

     object:nil]; //You can set object as nil or send the object you want to get from the ViewController

方法“-（无效）接收通知：（NSNotification*）通知”
换行

notif = [NSMutableArray arrayWithObjects:checkAlert, nil];

到

我做了一个if-else语句来实现它。但是谢谢你！
