iOS第三方登录大全(上)

Posted on

QQ、微信、微博接入

通用说明

所有第三方登录都需遵循以下步骤：

  • 注册第三方应用的AppID、Key、Secret
  • 添加第三方SDK及其所需系统依赖库,各文档内有详细说明,若依旧编译错误请参考下图加入所有库:

  • 在Targets->Info->URL Types添加各自的URL Schemes
  • 在info.plist添加LSApplicationQueriesSchemes字段并添加白名单
  • 在AppDelegate中初始化，各自回调，实现代理
  • 具体请看下文

@property TencentOAuth *tencentOAuth;

@property (nonatomic,copy)void (^thirdLoginSuccess)(NSDictionary *);
@property (nonatomic,copy)void (^thirdLoginFailure)(NSError *);

@end


@implementation CIAccountThirdLoginUtil
//获取单例
+ (CIAccountThirdLoginUtil *)getInstance{
    if (!thirdLogin) {
        thirdLogin = [[CIAccountThirdLoginUtil alloc] init];
        
    }
    
    return thirdLogin;
}

    _tencentOAuth = [[TencentOAuth alloc] initWithAppId:QQ_APP_ID andDelegate:self];
    NSArray *permissions= [NSArray arrayWithObjects:@"get_user_info",@"get_simple_userinfo",@"add_t",nil];

    }
}
//没有网络
- (void)tencentDidNotNetWork{
    NSError *error = [CIAccountError createError:ErrorNetNone];
    _thirdLoginFailure(error);
}
//获取回调的用户信息
- (void)getUserInfoResponse:(APIResponse *)response{

2.8 tips

  • 开发者接入微信登录时，先检测用户手机是否已安装微信客户端（使用sdk中isWXAppInstalled函数 ），对未安装的用户隐藏微信登录按钮，只提供其他登录方式
    • 微信自身有一个bug，如果未登录微信返回后没有回调接口，无法判断到回调
