iOS app提交审核被拒，给出的理由是Guideline 5.1.1(v) - Data Collection and Storage

昨天下午iOS版的app又提交了一个新的版本，早上起来一看，被拒了，被拒的原因是 Guideline 5.1.1，原文如下：

Bug Fix Submissions

The issues we've identified below are eligible to be resolved on your next update. If this submission includes bug fixes and you'd like to have it approved at this time, reply to this message and let us know. You do not need to resubmit your app for us to proceed.

Alternatively, if you'd like to resolve these issues now, please review the details, make the appropriate changes, and resubmit.

Guideline 5.1.1(v) - Data Collection and Storage
We noticed that your app supports account creation but does not appear to include an option to initiate account deletion.

Apps that support account creation must also offer account deletion to give App Store users more control of the data they've shared while using your app.

Next Steps

If your app already supports account deletion, reply to this message and let us know how to locate this feature. If your app does not support account deletion, revise your app to include an option to initiate account deletion and delete all user data you are not legally required to retain.

If you are unable to offer account deletion or need to provide additional customer service flows to facilitate and confirm account deletion, either because your app operates in a highly-regulated industry or for some other reason, reply to this message in App Store Connect and provide additional information or documentation. If you have questions regarding your legal obligations, check with your legal counsel.

Keep these requirements in mind when updating your app to support account deletion:

- Only offering to temporarily deactivate or disable an account is insufficient.
- If users need to visit a website to finish deleting their account, include a link directly to the page on your website where they can complete the process.
- You may include confirmation steps to prevent users from accidentally deleting their account. However, only apps in highly-regulated industries may require users to use customer service resources, such as making a phone call or sending an email, to complete account deletion.

原因分析：

原因很简单，是因为这个app提供了游客模式登录，但是游客登录模式目前不打算提供了删除账户的功能，补充完用户名和密码成为正式注册用户后，才会有删除账户的功能。

苹果给的解决方案：

1、如果app支持删除账户的功能，那么只需要回复邮件说明情况即可，不需要重新提交版本。

2、如果app没有删除账户的功能，那就需要修复issue后，重新提交版本审核。

当时想的是，如果用户没有成为注册用户，就不提供删除账户的功能，因为一删除账户，用户的数据就没了。现在想想，好像游客账户也能提供删除账户的功能，用户主动选择删除数据的，没了也没什么关系。

本次解决方案：

这次打算采用回复邮件的办法，先把游客模式不支持删除账户这个功能保留下来，为了更好的留住用户，如果以后再因为这个原因被拒，那就直接把这个功能放开。回复的邮件如下：

Hi, we notice that you can delete account when you use app as a visitor, because we believe that registration has not been completed when you use app as a visitor.

when you submit your usename and password on the profile page, we consider you have completed registation. At this point, you can delete your account.

that all, thank you.
