Я создаю будильник, в котором я хочу, чтобы при наступлении выбранного времени через Datepicker вместо появления только уведомлений и значков я хотел воспроизвести свой пользовательский звуковой файл, то есть jet.wav (он длится менее 30 секунд и в формате .wav).я хочу, чтобы, как только произойдет мое уведомление, он должен воспроизводить звук, и когда я нажимаю на приложение или вид оповещения, он должен остановиться. Итак, кто-нибудь может мне помочь. вот что я пытаюсь :-

Код:-

 @class The420DudeViewController;

@interface The420DudeAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    The420DudeViewController *viewController;

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet The420DudeViewController *viewController;

extern NSString *kRemindMeNotificationDataKey;

Согласно документации для soundName , вы должны

укажите имя файла (включая расширение) звукового ресурса в основном пакете приложения

Таким образом, я предлагаю вам изменить эту строку -[The420DudeViewController onTapSetAlarm] :

     notif.soundName = [[NSBundle mainBundle]pathForResource:@"jet" ofType:@"wav"];
  

к следующему:

     notif.soundName = @"jet.wav";
