iOS通知无法播放声音

Question

我已使用iOS 8在iOS应用程序中创建了一个通知。尽管已注册UIUserNotificationTypeSound并指定了默认声音名称，但通知已正确显示，但未播放声音。 收到通知后如何播放声音？

注册UIUserNotificationTypeSound

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]]

        return YES;
    }

设置默认声音名称

localNotif.soundName = UILocalNotificationDefaultSoundName;

我尚未测试您的代码，但与我的代码相比，我发现您没有调用[application registerForRemoteNotifications]; 方法

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
    // iOS 8 Notifications
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

    [application registerForRemoteNotifications];
}

试试这个，我想它将对您有帮助。
