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
我要评论
//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];
}
});
});
}
