ios - 本地通知计时器重置

Question

我有定时器重置的问题。如何让计时器休息以开始计算通知，这意味着在按下最后一个按钮之前有 200 秒的延迟？

- (IBAction)buttonPressed:(id)sender {
    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:200];
    localNotification.soundName = UILocalNotificationDefaultSoundName;
    localNotification.alertBody = @" More Quiz ";
    localNotification.timeZone = [NSTimeZone defaultTimeZone];

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

Answer 1

你不知道。只需调用 cancelLocalNotification: 并安排一个新通知。
