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]; } }); }); }
