UILocalNotification声音循环运行

Question

我有一个5.0秒的aiff文件。我想循环播放30秒。请指导我怎么做。现在我通过下面的代码以正常的方式设置通知-

//Function to schedule local notification
-(void)schedulelocalnotification:(NSDate *)particularfiredate ringtone: (NSString *)particularringtone name:(NSString *)alarmname info:(NSDictionary *)dicttext
{
    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.fireDate = particularfiredate;
    notification.soundName = [arrayAIFFFiles objectAtIndex:[arraysoundfilesnames indexOfObject:particularringtone]];
    notification.alertBody = alarmname;
    notification.userInfo = dicttext;
    [[UIApplication sharedApplication] scheduleLocalNotification:notification];
}

请注意，我不希望通知横幅和通知出现6次，只是声音应该重复30秒。

如果我不这样做，并添加一个30秒的声音文件，那么声音将持续到30秒，如果用户在此期间关闭通知，并打开应用程序，声音将继续播放。UILocalNotification的声音不会停止播放

我通过定期创建多个通知来修复它，这将是轨道的持续时间。下面是我的代码:

-(void)schedulelocalnotification:(NSDate *)particularfiredate ringtone: (NSString *)particularringtone name:(NSString *)alarmname info:(NSDictionary *)dicttext
{//post one single notification here with alert body, so that there are no multiple banners for each notification.
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = particularfiredate;
notification.soundName = [arrayAIFFFiles objectAtIndex:[arraysoundfilesnames indexOfObject:particularringtone]];
notification.alertBody = alarmname;
notification.userInfo = dicttext;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
totalDuration = totalDuration + [[arraySoundDuration objectAtIndex:[arraysoundfilesnames indexOfObject:particularringtone]]floatValue];
while (totalDuration<30) {//while time is less than 30 secs, which is the desired time.
     NSDate *newDate1 = [particularfiredate dateByAddingTimeInterval:totalDuration];
    UILocalNotification *notification1 = [[UILocalNotification alloc] init];
    notification1.fireDate = newDate1;
    notification1.soundName = [arrayAIFFFiles objectAtIndex:[arraysoundfilesnames indexOfObject:particularringtone]];
    //    notification1.alertBody = alarmname;//create notification without alert body, just with the sound file, so there are no multiple banners.
    notification1.userInfo = dicttext;
    [[UIApplication sharedApplication] scheduleLocalNotification:notification1];
    totalDuration = totalDuration + [[arraySoundDuration objectAtIndex:[arraysoundfilesnames indexOfObject:particularringtone]]floatValue];
}
totalDuration = 0;
}
