当我点击从我的应用程序发布的帖子时，我正在尝试从 Facebook 打开我的应用程序。

我在developers.facebook 注册了我的应用程序。

我在我的 Facebook 应用设置中启用了深度链接。

我已经为应用程序创建了 URL 方案。

注意：我的应用没有发布到应用商店。（苹果应用商店和 Facebook 应用中心）

我尝试了以下方法：但是，该帖子已成功发布，但当我点击该帖子时，Facebook 并未打开我的应用程序。

单程：

    // Create an object
    NSDictionary *properties = @{
                                 @"og:type": @"books.book",
                                 @"og:title": @"A Game of Thrones",
                                 @"og:description": @"In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
                                 @"books:isbn": @"0-553-57340-3",
                                 };
    FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];

    // Create an action
    FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
    action.actionType = @"books.reads";
    [action setObject:object forKey:@"books:book"];

    // Create the content
    FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
    content.action = action;
    content.previewPropertyName = @"books:book";

    FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];

    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fbauth2://"]]){
        dialog.mode = FBSDKShareDialogModeNative;
    }
    else {
        dialog.mode = FBSDKShareDialogModeBrowser; //or FBSDKShareDialogModeAutomatic
    }
    dialog.shareContent = content;
    dialog.delegate = self;
    dialog.fromViewController = self;
    [dialog show];

另一种方式：

   FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];

    content.contentURL = [NSURL URLWithString:@"https://developers.facebook.com"];
    content.contentTitle=@"TestSHare";

    FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];

    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fbauth2://"]]){
        dialog.mode = FBSDKShareDialogModeNative;
    }
    else {
        dialog.mode = FBSDKShareDialogModeBrowser; //or FBSDKShareDialogModeAutomatic
    }
    dialog.shareContent = content;
    dialog.delegate = self;
    dialog.fromViewController = self;
    [dialog show];

Facebook 正在打开应用中心页面。但不是我的应用程序。

深度链接是否仅在应用发布时才有效？

有什么原因吗？
