ShareSDK 微信授权登录注意点

ShareSDK 微信授权登录

[ShareSDK getUserInfo:SSDKPlatformTypeWechat
       onStateChanged:^(SSDKResponseState state, SSDKUser *user, NSError *error) {
       if (state == SSDKResponseStateSuccess) {
            // Event Handler ...
       }
}

在授权之前，如果设备是已经授权过了（是设备，不是微信）。需要先调用取消授权方法，不然的话返回始终都是第一次授权的微信的信息，切换微信号无法获得新微信的信息（有缓存）

if([ShareSDK hasAuthorized:SSDKPlatformTypeWechat]) {
    [ShareSDK cancelAuthorize:SSDKPlatformTypeWechat result:^(NSError *error) {
        NSLog(@"%@", error);
    }];
}

[ShareSDK getUserInfo:SSDKPlatformTypeWechat
       onStateChanged:^(SSDKResponseState state, SSDKUser *user, NSError *error) {
       if (state == SSDKResponseStateSuccess) {
            // Event Handler ...
       }
}
