问题描述

我正在使用iOS 7，但我的推送通知无法播放声音.

I am using iOS 7 and my push notifications do not play sounds.

奇怪的是，我发现我的应用程序的首选项">通知中心"中没有声音设置.以下是我的应用程序的通知中心的屏幕截图:

Strangely, I found there is no setting for sound in the Preference > Notification Center for my app. Following is the screenshots of Notification center for my app:

以下是Skype的内容:

And following is that for Skype:

您看到的是，我的应用程序没有声音"部分.

You see, there is no 'Sounds' section for my app.

有人可以帮忙吗?

更新:

现在我已经在我的应用程序中注册了声音.通知中心现在看起来像:

Now I have registered sound in my app. The Notification Center now looks like:

，并且我的通知有声音.看起来不错.

and my notification has sounds. Looks good.

但是，当我输入应用程序的设置后，最初有一个声音"部分，如Skype，但随后首选项"应用程序崩溃了，此后，不再有声音"部分，如下所示:

But after I enter the setting of my app, there is initially a 'Sounds' section like Skype, but then the Preference app crashed, and after that, there is no more 'Sounds', just like below:

可能是Apple的错误吗?

Might it be a bug of Apple?

推荐答案

您尚未在应用中注册音频推送通知.只需在您的应用程序委托中注册即可:

You're not registered for audio push notifications in your app. Just register for it like this in your App Delegate:

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //Whatever you have already in your app delegate...

    // Let device know you're going to be sending one of these types of notifications.
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
        (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

    return YES;
}

这5种类型是:

1. UIRemoteNotificationTypeBadge
2. UIRemoteNotificationTypeSound
3. UIRemoteNotificationTypeAlert
4. UIRemoteNotificationTypeNone
5. UIRemoteNotificationTypeNewsstandContentAvailability
