本文实例为大家分享了iOS微信第三方登录，供大家参考，具体内容如下

一、准备工作
1、到微信开放平台注册成开发者，获取appid
2、导入WeChatConnection.framework
3、配置URL Schemes 输入appid 例如wx29ce0f21ea982cb8

二、配置AppDelegate.m

1、注册微信

//微信登陆 [WXApi registerApp:WeiXin_AppId withDescription:@"weixin"];

2、设置函数

//把代理设置到登陆视图中- (BOOL)application:(UIApplication *)application    handleOpenURL:(NSURL *)url {   return [WXApi handleOpenURL:url delegate:[LoginViewController shareLogin]]; }

- (BOOL)application:(UIApplication *)application       openURL:(NSURL *)url  sourceApplication:(NSString *)sourceApplication      annotation:(id)annotation {   return [WXApi handleOpenURL:url delegate:[LoginViewController shareLogin]]; }

三、登陆页代码

1、微信登录授权比较复杂，相比QQ，新浪多了几步，简单说就是需要三步，第一步，获取code，这个用来获取token，第二步，就是带上code获取token，第三步，根据第二步获取的token和openid来获取用户的相关信息

2、

第一步：获取code

-(void)weiXinLogin {   SendAuthReq* req =[[SendAuthReq alloc] init];   req.scope = @"snsapi_userinfo,snsapi_base";   req.state = @"0744" ;   [WXApi sendReq:req]; }  -(void)onReq:(BaseReq *)req {   NSLog(@"呵呵");   [self msgHint:@"登陆失败"]; }  -(void)onResp:(BaseResp *)resp {   SendAuthResp* sender = (SendAuthResp*)resp;   NSString* code = sender.code;   NSLog(@"啦啦 code = %@",code);      MBProgressHUD * hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];   hud.labelText = @"收取用户信息..";   [self getAccess_tokenWithCode:code]; }

第二步获取token

-(void)getAccess_tokenWithCode:(NSString*)myCode {   //https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code      NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code",kWXAPP_ID,kWXAPP_SECRET,myCode];      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{     NSURL *zoneUrl = [NSURL URLWithString:url];     NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil];     NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding];     dispatch_async(dispatch_get_main_queue(), ^{       if (data) {         NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];         NSString* token = [dic objectForKey:@"access_token"];         NSString* openid = [dic objectForKey:@"openid"];         [self getUserInfoWithToken:token openId:openid];         NSLog(@"token = %@",token);         NSLog(@"openid = %@",openid);                         }     });   }); }

第三步：获取用户信息

-(void)getUserInfoWithToken:(NSString*)myToken openId:(NSString*)myOpenId {   // https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID      NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/userinfo?access_token=%@&openid=%@",myToken,myOpenId];   NSLog(@"infoUrl = %@",url);   dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{     NSURL *zoneUrl = [NSURL URLWithString:url];     NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil];     NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding];     dispatch_async(dispatch_get_main_queue(), ^{       if (data) {         NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];         NSString* nickName = [dic objectForKey:@"nickname"];         NSString* wxHeadImgUrl = [dic objectForKey:@"headimgurl"];                  NSLog(@"nickName = %@",nickName);         NSLog(@"headImg = %@",wxHeadImgUrl);                  NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];         [userDefaults setObject:ON forKey:LogState];         [userDefaults setObject:ThirdFoudationLogin forKey:LogType];         [userDefaults setObject:nickName forKey:LoginName];         [userDefaults setObject:wxHeadImgUrl forKey:UserHeaderPath];         [userDefaults synchronize];                  [MBProgressHUD hideAllHUDsForView:self.view animated:YES];         [self msgHint:@"微信登陆成功"];         [self popView];       }     });        }); }
