谷歌登录 API

Question

首先需要说的是，我不使用 CocoaPods。这是我第一次使用 Google API。
在 Google 指南中说我需要GIDSignIn在application:didFinishLaunchingWithOptions:方法中进行配置，但我也使用在此方法中配置的 Facebook API。此外，当我尝试在此方法中配置 G API 时，我收到错误：Type 'AppDelegate' does not conform to protocol 'GIDSignInDelegate'和Value of type 'GIDSignIn' has no member 'configureWithError'.
如何GIDSignIn在 AppDelegate 中不配置？

Answer 1

对于 swift 5 Xcode 10.3（最新的谷歌登录：Pod：5.0.2）

Replace:

    GIDSignIn.sharedInstance().handleURL(url,
                sourceApplication: sourceApplication,
                annotation: annotation)

With: 

    GIDSignIn.sharedInstance().handle(url)

在按钮上单击

@IBAction func googleLoginBtnPressed(_ sender: AnyObject) {
        GIDSignIn.sharedInstance()?.presentingViewController = self
        GIDSignIn.sharedInstance()?.restorePreviousSignIn()

        GIDSignIn.sharedInstance().signIn()
    }
