Swift QQ授权登录，并获取个人信息（用户资料）的例子

1，腾讯开放平台注册，以及SDK的配置（这个可以官方去找)

2，登录授权，并获取用户资料信息

import UIKit
 
class ViewController: UIViewController, TencentSessionDelegate{
     
    var _tencentOAuth:TencentOAuth!
     
    override func viewDidLoad() {
        super.viewDidLoad()
         
        _tencentOAuth = TencentOAuth.init(appId: "1105212016", andDelegate: self)
    }
     
    //登录按钮点击
    @IBAction func login(sender: AnyObject) {
        //设置权限列表
        let permissions = ["get_user_info","get_simple_userinfo"];
        //登陆
        _tencentOAuth.authorize(permissions)
    }
     
    //登陆完成调用
    func tencentDidLogin() {
        if !_tencentOAuth.accessToken.isEmpty {
            print("----------------------------------------")
            print("登录成功！")
            print("openId：\(_tencentOAuth.openId)",
                "accessToken：\(_tencentOAuth.accessToken)",
                "expirationDate：\(_tencentOAuth.expirationDate)")
            print("开始获取用户资料")
            _tencentOAuth.getUserInfo()
        }else {
            print("登录失败！没有获取到accessToken")
        }
    }
     
    /**
    * 登录失败后的回调
    */
    func tencentDidNotLogin(cancelled:Bool) {
        if cancelled {
             print("用户取消登录!")
        }else{
             print("登录失败!")
        }
    }
     
    /**
    * 登录时网络有问题的回调
    */
    func tencentDidNotNetWork() {
        print("没有网络，无法登录!")
    }
     
    /**
     * 取得用户信息的回调
     */
    func getUserInfoResponse(response:APIResponse) {
        print("----------------------------------------")
        print("用户资料获取成功：")
        print(response.jsonResponse)
    }
     
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

3，退出登录

要退出登录、取消授权。只需要调用 TencentOAuth 对象的 logout() 方法即可。

_tencentOAuth.logout(self)
