为什么6s机型微信登录的回调方法不走，导致登录不了

[ljw215]

[[UMSocialManager defaultManager] getUserInfoWithPlatform:UMSocialPlatformType_WechatSession currentViewController:nil completion:^(id result, NSError *error) {
if (error) {

    } else {
        UMSocialUserInfoResponse *resp = result;
        // 授权信息
        NSLog(@"Wechat uid: %@", resp.uid);
        NSLog(@"Wechat openid: %@", resp.openid);
        NSLog(@"Wechat accessToken: %@", resp.accessToken);
        NSLog(@"Wechat refreshToken: %@", resp.refreshToken);
        NSLog(@"Wechat expiration: %@", resp.expiration);
        // 用户信息
        NSLog(@"Wechat name: %@", resp.name);
        NSLog(@"Wechat iconurl: %@", resp.iconurl);
        NSLog(@"Wechat gender: %@", resp.gender);
        // 第三方平台SDK源数据
        NSLog(@"Wechat originalResponse: %@", resp.originalResponse);
    }
}];

6s机型这个回调进不来
