自定义Google登录按钮 - iOS

Question

我想自定义Google登录按钮,如下所示: -

我尝试了下面的链接,但没有一个帮助真的: - 如何自定义谷歌登录按钮？
https://developers.google.com/identity/sign-in/ios/

有人可以指导我应该做什么吗？我无法使用Google+登录按钮,因为" 不赞成使用Google+登录 ".

编辑: - 我尝试了以下链接提供的代码: -

Answer 1

您可以添加自己的按钮,而不是使用Google登录按钮

目标C版

1)将自己的按钮添加到storyBoard中

2)将动作拖动到viewController中

- (IBAction)googlePlusButtonTouchUpInside:(id)sender {
     [GIDSignIn sharedInstance].delegate = self;
     [GIDSignIn sharedInstance].uiDelegate = self;
     [[GIDSignIn sharedInstance] signIn];
  }

3)处理委托方法

#pragma mark - Google SignIn委托

- (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error {

  }

//提供一个提示用户使用Google登录的视图

- (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController
{
    [self presentViewController:viewController animated:YES completion:nil];
}

//关闭"使用Google登录"视图

- (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController {
    [self dismissViewControllerAnimated:YES completion:nil];

}

//已完成登录

- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user
     withError:(NSError *)error {
//user signed in
//get user data in "user" (GIDGoogleUser object)
}

Swift 4版本

在Swift中,确保添加了briding header,因为库是用目标C编写的

1)将自己的按钮添加到storyBoard中

2)将动作拖动到viewController中

@IBAction func googlePlusButtonTouchUpInside(sender: AnyObject) {
      GIDSignIn.sharedInstance().delegate=self
      GIDSignIn.sharedInstance().uiDelegate=self
      GIDSignIn.sharedInstance().signIn()
} 

3)处理委托方法

// MARK:Google SignIn代表

func signInWillDispatch(_ signIn: GIDSignIn!, error: Error!) {
}

//提供一个提示用户使用Google登录的视图

func signIn(_ signIn: GIDSignIn!,
    presentViewController viewController: UIViewController!) {
  self.present(viewController, animated: true, completion: nil)
}

//关闭"使用Google登录"视图

func signIn(_ signIn: GIDSignIn!,
    dismissViewController viewController: UIViewController!) {
  self.dismiss(animated: true, completion: nil)
}

//已完成登录

   public func signIn(_ signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
      withError error: Error!) {
        if (error == nil) {
          // Perform any operations on signed in user here.
          let userId = user.userID                  // For client-side use only!
          let idToken = user.authentication.idToken // Safe to send to the server
          let fullName = user.profile.name
          let givenName = user.profile.givenName
          let familyName = user.profile.familyName
          let email = user.profile.email
          // ...
        } else {
          print("\(error.localized)")
        }
    }

编辑:以下是使用自定义按钮,Google Doc参考的参考/证据

5.如果要自定义按钮,请执行以下操作:在视图控制器的.h文件中,将登录按钮声明为属性.

- (IBAction)googlePlusButtonTouchUpInside:(id)sender {
     [GIDSignIn sharedInstance].delegate = self;
     [GIDSignIn sharedInstance].uiDelegate = self;
     [[GIDSignIn sharedInstance] signIn];
  }

将按钮连接到刚刚声明的signInButton属性.通过设置GIDSignInButton对象的属性来自定义按钮.接下来,您可以实现并处理注销按钮.

Swift 3版

在Swift中确保添加了briding header,因为库是用Objective C编写的.

1. 将自己的按钮添加到storyBoard中

2. 将动作拖动到viewController中

   @IBAction func googlePlusButtonTouchUpInside(sender: AnyObject) {
         GIDSignIn.sharedInstance().signIn()
   } 
   

3. 处理委托方法

   //MARK:Google SignIn Delegate
    func signInWillDispatch(signIn: GIDSignIn!, error: NSError!) {
     // myActivityIndicator.stopAnimating()
       }
   
   // Present a view that prompts the user to sign in with Google
      func sign(_ signIn: GIDSignIn!,
                 present viewController: UIViewController!) {
           self.present(viewController, animated: true, completion: nil)
       }
   
   // Dismiss the "Sign in with Google" view
    func sign(_ signIn: GIDSignIn!,
                 dismiss viewController: UIViewController!) {
           self.dismiss(animated: true, completion: nil)
       }
   
   //completed sign In    
   public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
   
           if (error == nil) {
         // Perform any operations on signed in user here.
               let userId = user.userID                  // For client-side use only!
              let idToken = user.authentication.idToken // Safe to send to the server
               let fullName = user.profile.name
              let givenName = user.profile.givenName
              let familyName = user.profile.familyName
              let email = user.profile.email
             // ...
           } else {
               print("\(error.localizedDescription)")
           }
       }
   

Answer 3

对于Swift 4 :(这是工作代码享受)

@IBAction func logimByGoogle(_ sender: Any) {
    GIDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().signIn()
}
//MARK:- Google Delegate
func sign(inWillDispatch signIn: GIDSignIn!, error: Error!) {

}

func sign(_ signIn: GIDSignIn!,
          present viewController: UIViewController!) {
    self.present(viewController, animated: true, completion: nil)
}

public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
                   withError error: Error!) {
    if (error == nil) {
        // Perform any operations on signed in user here.
        let userId = user.userID                  // For client-side use only!
        let idToken = user.authentication.idToken // Safe to send to the server
        let fullName = user.profile.name
        let givenName = user.profile.givenName
        let familyName = user.profile.familyName
        let email = user.profile.email
        // ...
    } else {
        print("\(error)")
    }
}
