FBSharebutton始终在webview中打开sharedialog

Question

我正在我的项目中实现FBShareButton，但共享对话框总是打开WebView / Safari View而不是facebook native app。我正在使用facebook SDK 4.6＆amp; xcode 7 ..当我单独使用共享对话框时，它会在应用程序中打开，但是当我使用FBShareButton打开共享对话框时，它总是在Web视图中打开...我的代码是

-(void)openFacebookDialog
{
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
  content.contentURL = [NSURL
    URLWithString:@"https://www.facebook.com/FacebookDevelopers"];
  FBSDKShareButton *shareButton = [[FBSDKShareButton alloc] init];
  shareButton.shareContent = content;  
  shareButton.center = self.view.center;
  [self.view addSubview:shareButton];
}
