停止重复本地通知iOS

Question

我每30秒初始化一次本地通知。我想在用户按下按钮停止本地通知后停止重复。

问题是我找不到办法。它每30秒重复一次

这就是我教育本地化的方法

  // Schedule the notification
    UILocalNotification* localNotification = [[UILocalNotification alloc] init];
    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:30];
    localNotification.alertBody = @"Testing Repeating Local Notification";
    localNotification.applicationIconBadgeNumber = 1;
    localNotification.timeZone = [NSTimeZone defaultTimeZone];
    localNotification.soundName = UILocalNotificationDefaultSoundName;
    localNotification.repeatCalendar = [NSCalendar currentCalendar];

    localNotification.repeatInterval = kCFCalendarUnitSecond;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

我试过了[[UIApplication sharedApplication] cancelAllLocalNotifications];。但它很有效。

Answer 1

您可以将repeatInterval设置为0.根据文档，如果设置为零，通知将被触发一次。因此，当按下停止按钮时，您可以执行以下操作

localNotification.repeatInterval = 0;
[[UIApplication sharedApplication] cancelAllLocalNotifications];

Answer 2

我解决了。

刚刚从上面的代码中删除了localNotification.repeatCalendar = [NSCalendar currentCalendar];。

您可以在应用程序处于活动状态时收到通知时删除通知。

就像

一样

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
    if (application.applicationState == UIApplicationStateActive)
    {
        NSLog(@"Application is active");

        /*
        ...
        do some process
        ...
        */

        //remove notification
        [application cancelLocalNotification:notification];
    }
    else
    {
        NSLog(@"Application is inactive");
    }
}
