Ios UIWebView未加载Google登录的所有页面

我正在构建一个带有Feedly身份验证的iOS应用程序。这个选择不是我做的，但我的任务是建造这个。因此，我在下面设置了

UIViewController

，其中包含

UIWebView

。此webview加载Feedly身份验证页面。然而，在我按下谷歌之后。然后键入我的凭据，webview不会加载任何内容。即使多次单击“提交”，也不会发生任何事情。我做错了什么？它可能是

localhost

作为

redirect\u uri

LoginWebViewController.h

#import <UIKit/UIKit.h>

@interface LoginWebViewController : UIViewController<UIWebViewDelegate>

@end

---

在输入我的凭据并按下谷歌的登录按钮后，它工作正常。它显示“feedly想访问页面…”。在设备上或使用其他google帐户进行尝试是的，但如果您单击“接受”以获取“feedly想要访问页面…”，则什么都不会发生…我认为您不是唯一一个看到以下内容的人：，这可能是他们在google身份验证中的问题。这实际上是我的问题。我不记得我已经贴了，虽然听起来很愚蠢。

#import "LoginWebViewController.h"

@interface LoginWebViewController ()
