@kera0a 看了下, vvebo 好像必须登陆购买 app 账号的 icloud 才能使用, app 做了限制, 也就是说打开 app 时候验证了收据(苹果提供这个 api).

@kera0a A 购买了 vvebo, BCDE 这四个人都用 A 的账号下载, 而且这 4 个人都登陆了自己的 iCloud 账号. 用你的方法, app 打开后, 生成 uuid 存储到 iCloud 中, 都是存储到了自己的 iCloud. 并不能限制多设备.

我也有相同的疑问, 苹果是否有提供给开发者获取当前登陆 iCloud 账号信息的 API?

之前 vvebo 作者发过:

> 有用户反馈平时工作手机不登录 iCloud 。我会更新一个版本，针对没有绑定 iCloud 的用户限制 3 台设备使用。

他是怎么实现的呢? 用户通过 store 下载后打开, app 能获取用户的当前 iCloud 账号吗? 搜了一下是获取不到这敏感信息的.

对于 TikTok 这个简单, 它主要是检测运营商, 可以通过一些工具(圈 x/surge)篡改掉某些接口. 或者干脆买一个澳门卡查到手机上就可以了. (当然也需要将它的所有 api 挂非大陆代理)

@gengchun 嗯, 躺过这个坑了, 就不想再躺了.


@terence4444 哈哈 我哪能那么说呢. 他又不懂中文, 我表达的也是很委婉的: "In short, it really will slow down our progress, and you should not care too much about codes, you should care the results/bugs/screens."

@terence4444 我也劝过老板, 你只需要关注最后的产出结果, app 是否流畅运行 /是否有 bug/ui 是否一致 /功能是否完善即可, 不懂技术就不要掺和技术, 但是 3 个印度人背后说我坏话(说我技术不行):

> There are 3 developer who all tell me the same. Do you doubt their expertise Fai?

我不会再跟这老板解释了. 直接去 upwork 上解决问题. 说再多只能带来更多冲突.

@kiritoxf ui 是有问题的, 不过也很容易解决, 全部都是 字体 lineSpace / 按钮输入框的高度 / 登录按钮的大小, 至于 checkbox 我给 UI 沟通过, 已经删掉了, 只是 ui 图还是没更新上去. 谷歌 icon 因为白色的背景 导致看起来视觉上有点小, 我在代码里已经尽量放大了一点, 使其看起来一致. 至于 dispute, 我应该在哪几个方面去回复一下?

还是要张口说, 不要怕表达不清楚, 说一句话 有几个重要的单词说对, 对面就能知道意思了. 当然讲的流利和用恰当的词汇需要多锻炼出来的. 和印度人开过很多会, 他们说的特别快, 而且也是有语法问题的(在他们日常书面交流中发现), 想要听明白印度人说的什么 只能抓几个他说的单词, 实在听不懂就让对面再重复一遍.

@MrZhaoyx 哈哈 对 我也想起了这个电影.

@edison0951 确实不过关, 这我承认. 我们项目是在 monday 上面管理, 每个任务都设置了 reviewer. 大部分都是印度人 A 来 review 页面, 关于登陆这些页面, 他已经 review 过并设置了 DONE 的状态.

@unco020511 我听说印度人都是个位数的, 难怪被挤走了. 是我入错地方了.

@BigDogWang 是的, 我也觉得应该我来弄 pr, 而不是突然来了一个人, 项目需求都不明白, 就直接重构了我的代码并且要求以后提 pr 给她.


@shyrock “跟设计差得也是有点远了，建议退一部分” 我们约定这个周结束, 在这个周内我可以把所有页面都调整成和设计图 100% 相似.


@luvsic ”产出质量有问题，导致老板不信任你“ 这是一部分, 另外一部分是老板亲口说的, 另外三个人在背后都说我代码质量有很大问题. 我倒是很想知道, 再给他们 2 个月, 能做成什么样.

@POPOEVER 合同结束后都有相互评价的.


@Shane client 已经在上面开了 dispute, 这是他写的:

> The service provider cheated us on his skills and did not deliver the work agreed in the contract. He didn't deliver in time and the work he delivered is incomplete and the quality of the code is with many problems.

> did not deliver the project in time. The code and code structure are insufficient and bad quality. The freelancer promised to deliver good quality. Instead he didn't listen to clients direction and ignore the timetable as well as the project requirements. We expect full refund.

> The freelancer also signed a contract with us. He better check the terms & conditions.

> We strongly recommend to remove the freelancer from your platform to avoid further damage to other clients.

事情已经升级到不可挽回的地步了. 这是我的回复:

> Client can not say like "bad quality". Because this is not the final results. It's easy to adjust some UI pages. Also the client is not polite while meeting, always say dirty words. He is not satisfy with our progress, because all the program logics are not clear, and there's no project manager can clear all requirements. I am just a frontend developer, he even let me to do some animations. I never told him I can do that. I have gave some screen recordings, and he was satisfy with my work. But now he said it's "bad". I really don't know what exactlly he thinks. And I will give some screenshots what he has ever said.

> "did not deliver the project in time" that's not true. In the beginning, Simon told us to build an APP like "REBO" app, this is realizable. And we all agree. But after our developing, the program became more and more complex, there are so many functions that is much bigger than "REBO" app. Also his UI pages are not clear for user logics, so it makes hard to code, we have to spend much time on figure out what, how and why this UI designed so. And with his new design, we can not deliver app in time, because it's UI is missing also.

附件里面也有很多证据, 包括我录制过一些视频给他, 他也觉得很满意, 都是他的直接回复"looks pretty good".

@g0thic
@maddot
@zyh94946 哈哈你们说的对, 我写的这个页面 ui 有问题. 的确落下了很多把柄. 既然做前端, 页面一定要和 ui 一致, 而且要 responsive 的宽高. 以后有机会再写, 一定要注意这点.

@botman 对 之前有听说过这种信息, 不太相信. 现在亲身体验, 英吹斯汀.


@markliu2013 谢谢提醒.

@hackfly 对, 里程碑就不会有这些问题了. 这对双方都公平.

@cszchen 90%以上代码都是我写的，最多时候只有俩开发者，所以我就觉得没太有必要 pr ，项目本身也很着急。


@toesbieya 我承认这个 ui 有问题，但大部分功能逻辑都没有实现。实在没太多功夫去细调。 细调这个需要专门花一些时间去一起去提，去改。

@qiaobeier 的确很赶时间，其次 ui 可以修改，这也不是最终要上架的版本。
