友盟iOS微信登陆没有回调的原因

1、在友盟文档中这样说：

链接

7.4  微信登录
添加配置文件参考文档：添加微信及朋友圈，添加相关库文件，配置URL schemes及添加系统回调

注意微信登录必须先在微信开放平台申请微信登录权限
在你的程序APPdelegate入口方法添加下面的代码

  #import "UMSocialWechatHandler.h"
    //设置微信AppId、appSecret，分享url
    [UMSocialWechatHandler setWXAppId:@"wxd930ea5d5a258f4f" appSecret:@"db426a9829e4b49a0dcac7b4162da6b6" url:@"http://www.umeng.com/social"];

在微信登录按钮中实现下面的方法

  UMSocialSnsPlatform *snsPlatform = [UMSocialSnsPlatformManager getSocialPlatformWithName:UMShareToWechatSession];

        snsPlatform.loginClickHandler(self,[UMSocialControllerService defaultControllerService],YES,^(UMSocialResponseEntity *response){

            if (response.responseCode == UMSResponseCodeSuccess) {

                UMSocialAccountEntity *snsAccount = [[UMSocialAccountManager socialAccountDictionary]valueForKey:UMShareToWechatSession];

                NSLog(@"username is %@, uid is %@, token is %@ url is %@",snsAccount.userName,snsAccount.usid,snsAccount.accessToken,snsAccount.iconURL);

            }

 });

在授权完成后调用获取用户信息的方法

//得到的数据在回调Block对象形参respone的data属性
[[UMSocialDataService defaultDataService] requestSnsInformation:UMShareToWechatsession  completion:^(UMSocialResponseEntity *response){
        NSLog(@"SnsInformation is %@",response.data);
    }];

2、实践使用时：

#pragma mark - 微信登录
- (void)loginViewClickedWeiXiButton{

    [UMSocialData setAppKey:@"55bb141a67e58e9f80001801"];
    [UMSocialWechatHandler setWXAppId:@"wx2802d4e49f68996f" appSecret:@"f1bf8a16c5f87570ab07782d3e0ab223" url:@"http://www.umeng.com/social"];
    UMSocialSnsPlatform *snsPlatform = [UMSocialSnsPlatformManager getSocialPlatformWithName:UMShareToWechatSession];
    snsPlatform.loginClickHandler(self,[UMSocialControllerService defaultControllerService],YES,^(UMSocialResponseEntity *response){
        //  获取微博用户名、uid、token等
        if (response.responseCode == UMSResponseCodeSuccess) {
             UMSocialAccountEntity *snsAccount = [[UMSocialAccountManager socialAccountDictionary]valueForKey:UMShareToWechatSession];
            NSLog(@"username is %@, uid is %@, token is %@ iconUrl is %@",snsAccount.userName,snsAccount.usid,snsAccount.accessToken,snsAccount.iconURL);
        }
    });

}

3、【坑在这里】没有回调时因为要在应用代理方法中增加：

//sdk
#import "UMSocialSnsService.h"

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return  [UMSocialSnsService handleOpenURL:url wxApiDelegate:nil];
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [UMSocialSnsService  applicationDidBecomeActive];
}

最后说明

• 微信的openid对应友盟里叫usid

下面是授权成功的回调数据：

- UMSocial:  makeRequestWithPath is /share/token/53290df956240b6b4a0084b3/, parameters is {
    "access_token" = "OezXcEiiBSKSxW0eoylIeJDUKD6z6dmr42JANLPjNN56WRFnd-vVJO37ma0gCpKY1v5q8EVEMwdQqzvXoFFpe1jQXUzjqukub9-228J8sjvugvVVQYvzkhyvAgItvkYmMIGD_cE2hAWUm44_qCB-oQ";

    sdkv = "4.2.3";
    to = wxsession;
    tp = 0;
    uid = 462ae0edb57d53dfd2affb5e4ae36ad;
    usid = oyAaTjrJMAb3qfCbyDRp3h0NKyew;
} 
[18:38:48.197( 2055)] - UMSocial:  actionType is 15 , received json Dic is {
    data =     {
    };
    msg = "no error";
    st = 200;
}
