- （void）finishedWithAuth：（GTMOAuth2Authentication *）auth error：（NSError *）error - Method is not call

Question

我想获取用户在我的应用中使用Google+登录的所有信息。

-(void)googleSignInButtonMethod{
    [[UIApplication sharedApplication] delegate];
    signIn = [GPPSignIn sharedInstance];
    signIn.clientID = kClientId;
    [signIn authenticate];
    signIn.shouldFetchGoogleUserID=YES;
    signIn.shouldFetchGoogleUserEmail = YES;
    signIn.scopes = @[ kGTLAuthScopePlusLogin ];
    signIn.delegate = self;
    [signIn authenticate];
}

之后，

- (void)finishedWithAuth:(GTMOAuth2Authentication *)auth
                   error:(NSError *)error {

    NSLog(@"Received Error %@  and auth object==%@",error,auth);
    if(!error) {
        NSLog(@"%@", signIn.authentication.userEmail);
    }
}

我按照谷歌+开发者网站提供的所有说明进行操作。我设置了所有代理并导入了所有重要文件。

Answer 1

在.h文件中

@property (weak, nonatomic) IBOutlet GIDSignInButton *gmailSignInButton;
-(IBAction)gmailBtn:(GIDSignIn *)sender;

在.m文件中

- (IBAction)gmailBtn:(GIDSignIn *)sender {
 [[AFNetworkReachabilityManager sharedManager]startMonitoring];

//Checking the Internet connection...
[[AFNetworkReachabilityManager sharedManager]setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status){
    if (status == AFNetworkReachabilityStatusReachableViaWWAN || status == AFNetworkReachabilityStatusReachableViaWiFi) {

        [GIDSignIn sharedInstance].uiDelegate = self;
        [[GIDSignIn sharedInstance] signIn];

    }else{
        NSLog(@"No Network");
    }
 }];
}

- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error {
 // Perform any operations on signed in user here.
 NSLog(@"user ID: %@",user.userID);
 NSLog(@"user Token: %@",user.authentication.idToken);
 NSLog(@"user name: %@",user.profile.name);
 NSLog(@"user givenName: %@",user.profile.givenName);
 NSLog(@"user family Name: %@",user.profile.familyName);
 NSLog(@"user email: %@",user.profile.email);

 NSURL *profileURL;
 if (user.profile.hasImage)
 {
    profileURL = [user.profile imageURLWithDimension:100];
 }

 NSMutableDictionary *userData = [NSMutableDictionary dictionary];
 [userData setValue:user.userID forKey:@"id"];
 [userData setValue:user.profile.givenName forKey:@"first_name"];
 [userData setValue:user.profile.familyName forKey:@"last_name"];
 [userData setValue:@"" forKey:@"gender"];
 [userData setValue:user.profile.email forKey:@"email"];
 [userData setValue:profileURL forKey:@"profileImg"];    
}

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

- (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];
}

  

*别忘了申报gmail委托GIDSignInUIDelegate，GIDSignInDelegate
