Question

请给我解决方案我很好我已经制作了一个闹钟应用程序，闹钟时间我设置了本地通知fireDate它正常工作，然后我尝试第二次（1个薄荷后的贪睡时间）我无法设置本地通知，当我尝试设置第二次本地通知，它不会按时发射，否则它会立即发生火灾这是我的代码

int getTrackValue=[[defaults valueForKey:@"alarmTrack"] intValue];
     NSString *soundName =[appDelegte.globalArrayTrack objectAtIndex:getTrackValue];
    // set up the notifier
    UILocalNotification *localNotification = [[UILocalNotification alloc]init];

    localNotification.fireDate = notiAlarmTime;
    localNotification.timeZone = [NSTimeZone systemTimeZone];
    localNotification.alertBody=@"Please Off Alarm";
    localNotification.alertAction = NSLocalizedString(@"Show", nil);
    localNotification.soundName = [NSString stringWithFormat:@"%@.m4a",soundName];//@"Gentle Rise.m4a";
    localNotification.hasAction = YES;

    // Schedule the notification
    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

第二次我只是改变时间并调用相同的功能请帮我请分享您的宝贵知识

Answer 1

如果您想要更改fireDate UILocalNotification，则无法在计划后立即更改cancel the notification reschedule it。

取消通知

 int getTrackValue=[[defaults valueForKey:@"alarmTrack"] intValue];
 NSString *soundName =[appDelegte.globalArrayTrack objectAtIndex:getTrackValue];
// set up the notifier

[[UIApplication sharedApplication] cancelAllLocalNotifications];
UILocalNotification *localNotification = [[UILocalNotification alloc]init];

localNotification.fireDate = notiAlarmTime;
localNotification.timeZone = [NSTimeZone systemTimeZone];
localNotification.alertBody=@"Please Off Alarm";
localNotification.alertAction = NSLocalizedString(@"Show", nil);
localNotification.soundName = [NSString stringWithFormat:@"%@.m4a",soundName];//@"Gentle Rise.m4a";
localNotification.hasAction = YES;

// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

ONE UILocalNotification只会触发一次。

要拥有MULTIPLE，您需要多个UILocalNotification个对象

ios第二次设置为localnofication fireDate它无法正常工作
