自定义Google登录GIDSignInDelegate协议的抛出异常 [英] Custom Google Sign In throw exception on GIDSignInDelegate protocol

问题描述

我正在obj-c中编写一个iOS应用程序，并使用Google SignIn SDK来执行Google SignIn流程。我想能够自定义按钮和动作一点，所以我继续实施根据他们的文档自己的 GIDSignInDelegate 的协议。但是它没有理由抛出异常。

这是我的视图控制器的最小代码。
viewcontroller.m

  #importViewController.h 
 #import< FBSDKLoginKit / FBSDKLoginKit.h> 
 
 @interface ViewController（）
 
 
 @property（weak，nonatomic）IBOutlet UIButton * GoogleSignIn; 
 
 @end 
 
 @implementation ViewController 
 
  - （void）viewDidLoad {
 [super viewDidLoad]; 
 //加载视图后，通常从笔尖进行任何其他设置。 
} 
 
  - （void）didReceiveMemoryWarning {
 [super didReceiveMemoryWarning]; 
 //处理可以重新创建的任何资源。 
} 
 
 
  - （IBAction）googleButtonTouchUpInside：（id）sender {
 [[GIDSignIn sharedInstance] signIn]; 
} 
 
 //仅当GIDSignInUIDelegate不是
 // UIViewController的子类时才执行这些方法。 
 
 //停止用户
 //按下登录按钮
  - （void）signInWillDispatch：（GIDSignIn *）signIn error：（NSError）时启动的UIActivityIndi​​catorView动画*）error {
 // [UIActivityIndi​​catorView stopAnimating]; 
} 
 
 //呈现提示用户使用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]; 
} 
 
 @end 
  

viewcontroller.h

  #import< UIKit / UIKit.h> 
 #import< Google / SignIn.h> 
 
 @interface ViewController：UIViewController< GIDSignInUIDelegate> 
 
 @end 
  

我有自定义需要任何委托方法登录流程谷歌文档
我错过了什么吗？

解决方案

这是google signIn的基本工作环境...所以检查你的错误

首先在按钮操作中使用

  GIDSignIn * signin = [GIDSignIn sharedInstance]; 
 signin.shouldFetchBasicProfile = true; 
 signin.delegate = self; 
 signin.uiDelegate = self; 
 [signin signIn]; 
  

然后为代表们

   - （void）signIn：（GIDSignIn *）signIn didSignInForUser：（GIDGoogleUser *）用户withError：（NSError *）错误{
 //对此登录的用户执行任何操作。 
 if（error == nil）{
 NSString * userId = user.userID; 
} else {
 NSLog（@％@，error.localizedDescription）; 
} 
} 
 
  - （void）signIn :( GIDSignIn *）signIn didDisconnectWithUser：（GIDGoogleUser *）用户withError：（NSError *）错误{
 //用户在这里断开应用程序时执行任何操作。 
} 
 
  - （void）signInWillDispatch：（GIDSignIn *）signIn错误：（NSError *）错误{
 NSLog（@％@，error.description）; 
} 
 
 //呈现提示用户使用Google登录的视图
  - （void）signIn：（GIDSignIn *）signIn presentViewController：（UIViewController *）viewController { 
 //当前视图控制器
} 
 
 //关闭使用Google登录视图
  - （void）signIn：（GIDSignIn *）signIn dismissViewController： （UIViewController *）viewController {
 //关闭视图控制器
} 
  

I'm writing an iOS app in obj-c and using Google SignIn SDK to do the Google SignIn flow. I wanna be able to customize the button and action a little it so I went ahead implementing the protocols of GIDSignInDelegate myself based on their documentation. But it throws and exception for no reason.

Here's the minimal code of my view controller. viewcontroller.m

    #import "ViewController.h"
    #import <FBSDKLoginKit/FBSDKLoginKit.h>

    @interface ViewController ()


    @property (weak, nonatomic) IBOutlet UIButton *GoogleSignIn;

    @end

    @implementation ViewController

    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
    }

    - (void)didReceiveMemoryWarning {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }


    - (IBAction)googleButtonTouchUpInside:(id)sender {
        [[GIDSignIn sharedInstance] signIn];
    }

    // Implement these methods only if the GIDSignInUIDelegate is not a subclass of
    // UIViewController.

    // Stop the UIActivityIndicatorView animation that was started when the user
    // pressed the Sign In button
    - (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error {
        //[UIActivityIndicatorView stopAnimating];
    }

    // Present a view that prompts the user to sign in with Google
    - (void)signIn:(GIDSignIn *)signIn
    presentViewController:(UIViewController *)viewController {
        [self presentViewController:viewController animated:YES completion:nil];
    }

    // Dismiss the "Sign in with Google" view
    - (void)signIn:(GIDSignIn *)signIn
    dismissViewController:(UIViewController *)viewController {
        [self dismissViewControllerAnimated:YES completion:nil];
}

@end

viewcontroller.h

#import <UIKit/UIKit.h>
#import <Google/SignIn.h>

@interface ViewController : UIViewController <GIDSignInUIDelegate>

@end

I do have whatever delegate method is required for a custom login flow google doc Did I miss anything?

解决方案

This is basic workaroung for google signIn ... so check what is missing for you

First of all in your button action use

GIDSignIn *signin = [GIDSignIn sharedInstance];
signin.shouldFetchBasicProfile = true;
signin.delegate = self;
signin.uiDelegate = self;
[signin signIn];

Then for Delegates

- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error {
    // Perform any operations on signed in user here.
    if (error == nil) {
        NSString *userId = user.userID;                  
    } else {
        NSLog(@"%@", error.localizedDescription);
    }
}

- (void)signIn:(GIDSignIn *)signIn didDisconnectWithUser:(GIDGoogleUser *)user withError:(NSError *)error {
    // Perform any operations when the user disconnects from app here.
}

- (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error {
    NSLog(@"%@",error.description);
}

// Present a view that prompts the user to sign in with Google
- (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController {
    //present view controller
}

// Dismiss the "Sign in with Google" view
- (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController {
      //dismiss view controller
 }
