iOS Google登录失败

我在上做了任何操作，但当我调用

GIDSignIn.sharedInstance（）.signIn（）

时，它崩溃了

代码： 在AppDelegate：

func configGoogleServer() {
    var configureError: NSError?
    GGLContext.sharedInstance().configureWithError(&configureError)
    assert(configureError == nil, "Error configuring Google services: \(configureError as Optional)")
    GIDSignIn.sharedInstance().delegate = self
}

在某些viewController上：

GIDSignIn.sharedInstance().signIn()

class ViewController: UIViewController,GIDSignInUIDelegate {

override func viewWillAppear(_ animated: Bool) {
        GIDSignIn.sharedInstance().delegate = self
        GIDSignIn.sharedInstance().uiDelegate = self
      }
}

我已经配置了URL方案，比如

com.googleusercontent.apps.598xxx…xxx

碰撞屏幕截图：

调试区域没有显示任何内容…：（

在ViewController中添加以下代码：

GIDSignIn.sharedInstance().signIn()

class ViewController: UIViewController,GIDSignInUIDelegate {

override func viewWillAppear(_ animated: Bool) {
        GIDSignIn.sharedInstance().delegate = self
        GIDSignIn.sharedInstance().uiDelegate = self
      }
}

您忘记执行委托：

func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {

    if let error = error {
      print(error.localizedDescription)
      return
    }
   else{
//handle response
}
  }

---

您将代理放在

AppDelegate.swift

中，这不是真的，您的AppDelegate应该是这样的：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // .. something else

        // GOOGLE
        // Initialize sign-in
        var configureError: NSError?
        GGLContext.sharedInstance().configureWithError(&configureError)
        assert(configureError == nil, "Error configuring Google services: \(configureError)")

        // No delegate here

        return true
    }

func application(_ application: UIApplication,
                     open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        return GIDSignIn.sharedInstance().handle(url,
                                                 sourceApplication: sourceApplication,
                                                 annotation: annotation)
    }

@available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
            if let sourceApplication = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String {
                let annotation = options[UIApplicationOpenURLOptionsKey.annotation]
                return GIDSignIn.sharedInstance().handle(url,
                                                         sourceApplication: sourceApplication,
                                                         annotation: annotation)
            }

            return true
        }

然后将SignIn委托放在您的ViewController中进行签名操作：ư

    class YourViewController: UIViewController  {
         // something else....

         func doSignIn() {
                GIDSignIn.sharedInstance().delegate = self
                GIDSignIn.sharedInstance().uiDelegate = self
                GIDSignIn.sharedInstance().scopes = YOUR_GOOGLE_SCOPES

                if GIDSignIn.sharedInstance().hasAuthInKeychain() {
                    GIDSignIn.sharedInstance().signInSilently()
                } else {
                    GIDSignIn.sharedInstance().signIn()
                }

          }
    }

extension YourViewController: GIDSignInDelegate, GIDSignInUIDelegate {
    func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
              withError error: Error!) {
        if let error = error {
            self.showMessage("Authentication Error", type: .error)
            self.service.authorizer = nil
        } else {
            self.service.authorizer = user.authentication.fetcherAuthorizer()
            // PUT YOUR METHOD AFTER SIGNED-IN HERE
        }
    }
}

你是如何安装sdk的？你可以找到google的示例代码添加抛出的确切错误。是的，你是对的，我应该将ViewController设置为委派，现在它已修复，谢谢！
