UILocalNotification聲音每隔一段時間播放

Question

每當我創建一個UILocalNotification並且它被觸發時，我只能每隔一秒播放一次自定義聲音。這隻發生在模擬器之外，在我的iPhone 5s上。

UILocalNotification* sessionEndNotification = [UILocalNotification new]; 
sessionEndNotification.fireDate = [self.dateAppMinimized dateByAddingTimeInterval:[self secondsLeft]]; 
sessionEndNotification.alertBody = @"Your session has finished. Remember to remain mindful through the rest of your day!"; 
sessionEndNotification.soundName = @"bell.caf"; 
[[UIApplication sharedApplication] scheduleLocalNotification:sessionEndNotification]; 

如果我將soundName更改爲UILocalNotificationDefaultSoundName，它每次都有效。 bell.caf長8秒。

我在做什麼錯？

謝謝！

我修正了它，但沒有做任何有意義的事情。我將代碼更改爲此並且它可以工作：

UILocalNotification* sessionEndNotification = [UILocalNotification new]; 
sessionEndNotification.soundName = @"endMeditationBell.aif"; 
sessionEndNotification.hasAction = YES; 
sessionEndNotification.fireDate = [self.dateAppMinimized dateByAddingTimeInterval:[self secondsLeft]]; 
sessionEndNotification.alertTitle = @"Session finished"; 
sessionEndNotification.alertBody = @"Your session has finished. Remember to remain mindful through the rest of your day!"; 
[[UIApplication sharedApplication] scheduleLocalNotification:sessionEndNotification];
