想了解iOS微信第三方登录实例的相关内容吗,st646889325在本文为您仔细讲解iOS微信第三方登录的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:iOS微信第三方登录,iOS第三方登录,下面大家一起来学习吧。

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]; 
      } 
    }); 
     
  }); 
}
