App平台和具体平台接入流程

2.1 在配置文件Info.plist中配置应用白名单，必须添加以下所有字段，否则可能无法跳转

<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fb-messenger-api</string>
<string>fbauth2</string>
<string>fbshareextension</string>
</array>

2.2 点击XCode项目名，选择Info，添加FaceBook的URL Types

identifier:fb URL Schemes:fb前缀后+FaceBook App ID（用户自己申请的账号）

2.3 Appdelegate中的配置

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //facebook
    [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
    [FBSDKSettings setAppID:Facebook_APP_ID];

      return YES;
}
// 2
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
    return  
    [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation]
}
// 3
- (void)applicationDidBecomeActive:(UIApplication *)application {

    [FBSDKAppEvents activateApp];
}

2.4 工具类中构造loginFacebook方法

- (void)loginFacebookSuccess:(UIViewController *)viewController success:(void (^)(id response))successBlock failure:(void (^)(NSError *error))failureBlock{
    FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    [login  logInWithReadPermissions: @[@"public_profile"]
     fromViewController:viewController
     handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
         if (error) {
             NSError *error = [CIAccountError createError:ErrorThirdLoginFailure];
             failureBlock(error);
         } else if (result.isCancelled) {
             NSError *error = [CIAccountError createError:ErrorThirdLoginCancel];
             failureBlock(error);
         } else {
             NSString *token = result.token.tokenString;
             FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                           initWithGraphPath:result.token.userID
                                           parameters:nil
                                           HTTPMethod:@"GET"];
             [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                                   id result,
                                                   NSError *error) {
                 if (error) {
                     NSError *resultError = [CIAccountError createError:ErrorThirdLoginFailure];
                     failureBlock(resultError);
                 }else{
                     NSString *nickName = [result objectForKey:@"name"];
                     NSString *openId = [result objectForKey:@"id"];
                     NSDictionary *resultDic = @{@"openid":openId,
                                                 @"nickname":nickName,
                                                 @"account_type":@"facebook",
                                                 @"access_token":token,
                                                 @"third_appid":Facebook_APP_ID};
                     successBlock(resultDic);
                 }
                 
             }];
         }
     }];
}

2.5 登录时调用loginFacebook方法

[thirdLoginUtil loginFacebookSuccess:self success:^(id response) {
           //获取数据实现客户端登录
           } failure:^(NSError *error) {
               [self ShowExclaHud:error.localizedDescription];
           }];

            if (token && openId && nickName) {
              
                NSDictionary *resultDic = @{@"openid":openId,
                                            @"nickname":nickName,
                                            @"account_type":@"twitter",

            }
            else{
                NSError *resultError = [CIAccountError createError:ErrorThirdLoginFailure];
                failureBlock(resultError);
            }
            
           
        }else
        {NSError *resultError = [CIAccountError createError:ErrorThirdLoginFailure];

<key>LSApplicationQueriesSchemes</key>
<array>
<string>com.google.gppconsent.2.4.1</string>
<string>com.google.gppconsent.2.4.0</string>
<string>com.google.gppconsent.2.3.0</string>
<string>com.google.gppconsent.2.2.0</string>

    return  
    [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation];
}

2.4 在登录中输入代码

[[GIDSignIn sharedInstance] signIn];

2.5 实现google+代理

#pragma mark - GIDSignInDelegate
- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user withError:(NSError *)error
{
    if (error) {
        [self ShowExclaHud:@"授权失败"];
    }else
    {

        NSDictionary *resultDic = @{@"openid":openId,
                                    @"nickname":nickname,
                                    @"account_type":@"google",
                                    @"access_token":token,
           
                                    @"third_appid":Google_APP_ID};
        //获得返回数据resultDic实现客户端登录

        
    }
}

- (void)signIn:(GIDSignIn *)signIn didDisconnectWithUser:(GIDGoogleUser *)user withError:(NSError *)error{
    if (error) {
        [self ShowExclaHud:@"授权失败"];
    }else{
        NSString *token = user.authentication.idToken;
        NSString *openId = user.userID;
        NSString *nikeName = user.profile.name;
        NSDictionary *resultDic = @{@"openid":openId,
                                    @"nikename":nikeName,
                                    @"account_type":@"google",
                                    @"access_token":token,
                                    @"third_appid":Google_APP_ID};
       //获得返回数据resultDic实现客户端登录
        
        
    }
}


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