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];
}
});
});
}
