聲音不工作UINotification

Question

我在iPad應用程序與我UINotification完成。我正在嘗試向我的通知消息添加聲音。我嘗試了默認和自定義之一，我已經添加到我的包中，但都不起作用。

[[UIApplication sharedApplication] cancelAllLocalNotifications]; 

UILocalNotification *localNotification = [[UILocalNotification alloc] init]; 
localNotification.fireDate = nil; 
localNotification.alertBody = @"Message"; 
localNotification.soundName = @"ALERT.mp3"; // UILocalNotificationDefaultSoundName 
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification]; 

兩者都不工作，我聽不到任何東西。

試試這個 並檢查你的聲音文件是否不應該大於30 秒。 在您的應用程序中寫下代表

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; 


- (void)scheduleNotification { 
    Class cls = NSClassFromString(@"UILocalNotification"); 
    if (cls != nil) { 
      UILocalNotification *notif = [[cls alloc] init]; 
      notif.fireDate = insert your date; 
      notif.timeZone = [NSTimeZone localTimeZone]; 
      notif.alertBody = your message body; 
      notif.repeatInterval = 0; 
      notif.soundName = UILocalNotificationDefaultSoundName; 
      [[UIApplication sharedApplication] scheduleLocalNotification:notif]; 
      [notif release]; 
    } 
}
