我试图在UIWebView
中实施1Password App Extension。我虽然没有运气。您可以在下面看到Controller
的{{1}}。当我按Google然后点击1Password按钮时,我可以选择我的Google帐户。但是,一旦我按下它,UIWebView
只会重新加载初始页面而已。我做错了什么?
UIWebView
我一直收到这个错误:

答案 0 :(得分:2)
事实证明,问题是我在viewWillAppear
中创建了视图。扩展名是叠加层,因此 - 在扩展程序完成后 - 调用viewWillAppear
。
我要解决此问题,将其移至viewDidLoad
。瞧,它有效。
