推荐答案

在 SFSafariViewControllerDelegate 中，您只有一种方法，可以提供帮助：

In SFSafariViewControllerDelegate you have only one method, that can help:

optional public func safariViewController(controller: SFSafariViewController, didCompleteInitialLoad didLoadSuccessfully: Bool)

但只有在初始（第一个）url加载时才会调用它。如果你有重定向并在auth过程中等待一些网址 - 它将无济于事。
然后你应该使用 UIWebView 并实现 UIWebViewDelegate 委托方法：

But it will be called only on initial (first) url loaded. If you have redirects and wait for some url in auth process - it will not help. Then you should use UIWebView and implement UIWebViewDelegate delegate method:

optional public func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool

但不记得是 ATS
