iOS 9上的GIDSignIn白屏 [英] GIDSignIn white screen on iOS 9
问题描述
我实现了Google登录，一切都可以在iOS 8上运行.但是，当我在iOS 9上调用此行时:
I implemented Google sign in and everything works on iOS 8. But when I call this line on iOS 9:
GIDSignIn.sharedInstance().signIn()
我可以第一次登录.但是，如果我取消，则下次尝试登录时，它将显示白屏，它将显示正常的用户批准Web视图.
I'm able to log in the first time. But if I cancel, the next time I try to log in it shows a white screen where the normal user approval web view would be.
甚至在删除应用程序并重新安装时也会发生这种情况，这意味着某些内容可能会在操作系统级别被缓存.
唯一的解决方案是重新打开iOS模拟器或重新启动iPhone.
The only solution is to reopen the iOS Simulator or restart my iPhone.
我已经尝试过所有 答案没有运气.我还尝试过GIDSignIn.sharedInstance().signIn().allowsSignInWithWebView = true希望通过Safari进行授权可能有效，但Safari永远不会打开.我的Podfile具有pod 'Google/SignIn'，所以我认为这不是版本问题.
I've tried all these answers with no luck. I've also tried GIDSignIn.sharedInstance().signIn().allowsSignInWithWebView = true hoping that authorizing through Safari might work, but Safari never opens. My Podfile has pod 'Google/SignIn' so I don't think it's a version issue.
我现在不知所措，因为这超出了我的应用程序的范围，我所能想到的就是解构一个可运行的示例应用程序，并将其设置与我的应用程序逐行比较.
I'm at a loss at this point, because this goes beyond the scope of my app, and all I can think of is to deconstruct a working example app and compare its settings with my app line by line.
有人链接到正在运行的示例应用程序吗?
Does someone have a link to a working example app?
推荐答案
因此，我遇到了与您完全相同的问题.我花了几个小时来尝试一切.我终于找到了一种解决方案，该解决方案可能并非100％正确，但对我有用，并解决了该问题.
So, I had exactly the same issue as you. It spent me hrs to try out everything. I finally found a solution, which might not be 100% correct, but it works for me and fixed the problem.
这就是我在项目中所做的. 首先，我自己实现了三个GIDSignInUIDelegate函数，这与正式文档存在冲突，因为我的GIDSignInUIDelegate是UIViewController的子类.但是我正在使用我的自定义签名按钮，当我遵循google官方文档时，该按钮不起作用.因此，我尝试了一切，发现它可行.
This is what I did in my project. First, I implemented the three GIDSignInUIDelegate functions myself, which is conflict to the official document because my GIDSignInUIDelegate is subclass to the UIViewController. But I am using my custom signing button, and it didn't work when I followed the google official document. So I tried out everything and found it works.
实现委托函数后，需要做两件事.
After you implemented the delegate function, there are two major things need to do.
-
在以下函数中，设置viewController.view.layoutIfNeeded()
In the following function, set viewController.view.layoutIfNeeded()
func sign(_ signIn: GIDSignIn!, present viewController: UIViewController!) {
//This line does the trick to fix signin web not showing issue
viewController.view.layoutIfNeeded()
self.present(viewController, animated: true, completion: nil)
}
不要在ViewDidLoad()中设置此委托
Don't set up this delegate in the ViewDidLoad()
GIDSignIn.sharedInstance().uiDelegate = self
相反，请在按钮操作中进行设置.否则，它将以某种方式一直显示委托人
Instead, set them up in the button action. Otherwise, it somehow keeps showing delegate
希望这会帮助您解决问题.
Hope it will help your problem.
