SFSafariViewController空白のページをロードする

Question

私はiOSアプリケーションでURLを開くためにSFSafariViewControllerを使用しています.ios 9では完全に動作していましたが、デバイスをiOS 10にアップデートした後、URLに空白バー..でもsafariViewController（コントローラ：SFSafariViewController、didCompleteInitialLoad didLoadSuccessfully：ブール値）コントローラーが提示された後にが呼び出さ取得されていません。..

はVC

import SafariServices 

コードでこれをインポートしています

  let url = NSURL(string: urlString)! 
      if #available(iOS 9.0, *) { 
       let safariVC = SFSafariViewController(URL: url) 
       safariVC.delegate = self 
       self.presentViewController(safariVC, animated: true, completion: { 
        self.hideHUD() 
       }) 
      } else { 
       // Fallback code 
      }

Answer 1

は、あなたがやっているなしにしようとされているすべてのロードアニメーションをコメントアウトしてみます。

... 
    // self.showHUD() 
    // self.hideHUD() 
... 

ので、メイン window

上記windowとして追加プログレスバーとローダーを使用しているとき、私は本当にAppleがよかったsafariViewController負荷を聞かせていないセキュリティ問題の修正中に導入さiOSの10のバグの

その変更を文書化した。 現在のアプリケーションでローディングインジケータをコメントアウトして機能させる必要がありました。

Answer 2

に直面した他の同じ問題を誰かに強要するためのリンクはSafariViewControllerを使用しようとすると、私は見ていたいくつかの同様の問題を見て、この出くわしています。私の問題をポップアップが存在するときにSafariViewControllerを使用するまで追跡しました。私の問題と可能な解決策を示すためにいくつかのコードをまとめました。

ViewController.swift：

/* 
This view controller tries to boil down to the essence of a problem seen 
when trying to use SafariViewController. The net result is DO NOT present 
the SafariViewController when a popup is present. 

This controller and the associated popup show 3 ways to 
present the SafariViewController: 

Always Good: This uses a button on the controller to simply call the 
showSVC() routine and never had a problem. 

Good: This is a work-around for the "Bad" case to follow. In this case, 
we are using a button in a popup to bring up the SafariViewController. 
The trick is to get rid of the popup before calling showSVC(). This is 
done by dismissing the popup immediately without animation and then 
adding a delay before calling showSVC(). Seems to work fine, but using 
delays to accomplish things always seems a bit suspect. Use at your own risk. 

Bad: When this goes bad, a blank white screen is presented with no way 
to escape. Using "Reset Content and Settings..." in the simulator can 
get one back to where it will work one time. It seemed originally that 
this worked on iOS9 but not on iOS10. But now seems to fail similarly 
on both iOS9 and iOS10. This case is dismissing the popup with animation 
while trying to bring up the SafariViewController. 

Other info: This view controller is embedded in a navigation controller - 
basically to provide a navigation bar and button to act as the anchor 
point for the popup. The popup provides two buttons that call back 
to this controller with the "PopButtonPressedProtocol". This controller 
uses the title in the popup's buttons to differentiate the "good" and 
"bad" cases. 

The problems shown by this example sounded similar to problems various 
others reported, but these reports may be for other reasons, which may 
or may not be similar.
