ios - 交互式通知中的操作未反射(reflect)在应用程序中

Question

我正在做一个使用 ios 8 交互式通知功能的示例应用程序。就显示通知而言，一切正常。但是当我在通知中选择一个 Action 时，会调用该 Action 的相应方法，但该方法中的代码不会反射(reflect)在应用程序中。

我的应用程序委托(delegate)实现通知的部分代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 [self setupNotification];
// Override point for customization after application launch.
return YES;
}

-(void)setupNotification
{
UIMutableUserNotificationAction *accept =[[UIMutableUserNotificationAction alloc]init];
accept.identifier =@"Accepted";
accept.title=@"Accept";
accept.destructive=NO;
accept.authenticationRequired=YES;
accept.activationMode=UIUserNotificationActivationModeBackground;

UIMutableUserNotificationAction *decline =[[UIMutableUserNotificationAction alloc]init];
decline.identifier =@"Rejected";
decline.title=@"Decline";
decline.destructive=YES;
decline.authenticationRequired=YES;
decline.activationMode=UIUserNotificationActivationModeBackground;

UIMutableUserNotificationCategory *actions =[[UIMutableUserNotificationCategory alloc]init];
[actions setIdentifier:@"customActions"];
[actions setActions:@[decline,accept] forContext:UIUserNotificationActionContextDefault];

NSSet* categories = [NSSet setWithArray:@[actions]];
UIUserNotificationSettings* settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:categories];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler
{
  if([notification.category isEqualToString:@"customActions"])
{
     ViewController *screen =[[ViewController alloc]init];
    if([identifier isEqualToString:@"Rejected"])
    {

        [screen deleteAction];
    }
    else if([identifier isEqualToString:@"Accepted"])
    {
        [screen acceptAction];
    }
}

//  Important to call this when finished
completionHandler();
}

我的 View Controller

    - (void)viewDidLoad
    {

    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    }

    -(void)deleteAction
    {
    NSLog(@"delete");
    [self.view setBackgroundColor:[UIColor redColor]];

    }
    -(void)acceptAction
   {
   NSLog(@"accept");
    [self.view setBackgroundColor:[UIColor greenColor]];
    }

    - (IBAction)sendNotification:(id)sender {

    UILocalNotification* notification = [[UILocalNotification alloc] init];
    [notification fireDate  ];
    [notification setAlertBody:@"Notification triggered"];
    [notification setCategory:@"customActions"];
    [[UIApplication sharedApplication] scheduleLocalNotification:notification];
     }

方法内的日志正在打印，但背景颜色没有改变。帮助我，我需要在我现有的应用程序中实现此功能。

迅速添加:

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
    Swift.print(identifier)
}

在 AppDelegate 中。一旦您按下通知中的操作按钮，它将调用
