Iphone 想在通知事件发生时播放我的声音文件，然后停止

我正在制作一个闹钟，我希望当通过Datepicker选择的时间发生时，而不仅仅是通知和徽章发生时，我希望播放我的自定义声音文件，即jet.wav（它的时间小于30秒，格式为.wav）。我希望在收到通知后立即播放声音，当我单击应用程序或警报视图时，它应该停止。谁能帮帮我吗。以下是我正在尝试的：-

代码：-

@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;






@implementation The420DudeAppDelegate

@synthesize window;
@synthesize viewController;

NSString *kRemindMeNotificationDataKey = @"kRemindMeNotificationDataKey";

根据for

soundName

，您应该

指定应用程序主捆绑包中声音资源的文件名（包括扩展名）

因此，我建议您更改这一行的

-[The420DudeViewController ontapsetalum]

：

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

对下列事项：

    notif.soundName = @"jet.wav";

非常感谢，我真是个笨蛋
