マルチプレイヤーマッチを可能にするゲームを開発しています。以前にマルチプレイヤー招待をテストしたことがあり、それらはすべて機能していました。一方のデバイスからリクエストを送信すると、もう一方のデバイスにバナーが表示され、招待が受け入れられるとゲームが開始されました。
2 日前にアプリを送信する直前に、この機能を再度テストしましたが、機能していないことがわかりました。

{
delegate = theDelegate;
self.presentingViewController = viewController;
if (!gameCenterAvailable) {
// Game Center is not available.
userAuthenticated = FALSE;
}
else{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
/*
The authenticateWithCompletionHandler method is like all completion handler methods and runs a block
of code after completing its task. The difference with this method is that it does not release the
completion handler after calling it. Whenever your application returns to the foreground after
running in the background, Game Kit re-authenticates the user and calls the retained completion
handler. This means the authenticateWithCompletionHandler: method only needs to be called once each
time your application is launched. This is the reason the sample authenticates in the application
delegate's application:didFinishLaunchingWithOptions: method instead of in the view controller's
viewDidLoad method.
Remember this call returns immediately, before the user is authenticated. This is because it uses
Grand Central Dispatch to call the block asynchronously once authentication completes.

xcode のデバッグ ウィンドウには、次のように表示されます。

上記の行の「I am []...」は重要ですか?
Ray Wenderlich のサイトからマルチプレイヤー ゲームを作成するためのチュートリアルをダウンロードして実行し、それを試してみました。両方のデバイスでフォアグラウンドで実行されていない限り、同じ問題が発生します。フォアグラウンドで実行している場合でも、アプリに招待リクエストが表示されません。
他の誰かがこの問題を経験したことがありますか、または何が起こっているのか考えていますか? authenticateLocalUser は applicationDidFinishLaunching から呼び出されます
