Apple警告邮件，禁用JS热更新机制

3.8节一大早相信不少iOS开发者都收到了来自Apple的一封警告邮件：

Dear Developer,Your app, extension, and/or linked framework appears to contain code designed explicitly with 
the capability to change your app’s behavior or functionality after App Review approval, which is not in 
compliance with section 3.3.2 of the [Apple Developer Program License Agreement]
(https://itunesconnect.apple.com/WebObjects/iTunesConnect.woa/ra/ng/%E2%80%9Chttps://developer.apple.com/terms/%E2%80%9C) and [App Store Review Guideline 2.5.2]
(https://itunesconnect.apple.com/WebObjects/iTunesConnect.woa/ra/ng/%E2%80%9Chttps://developer.apple.
com/app-store/review/guidelines/#software-requirements”). This code, combined with a remote resource, can 
facilitate significant changes to your app’s behavior compared to when it was initially reviewed for the App 
Store. While you may not be using this functionality currently, it has the potential to load private frameworks, 
private methods, and enable future feature changes. This includes any code which passes arbitrary 
parameters to dynamic methods such as dlopen(), dlsym(), respondsToSelector:, performSelector:, 
method_exchangeImplementations(), and running remote scripts in order to change app behavior or call SPI, 
based on the contents of the downloaded script. Even if the remote resource is not intentionally malicious, it 
could easily be hijacked via a Man In The Middle (MiTM) attack, which can pose a serious security 
vulnerability to users of your app.Please perform an in-depth review of your app and remove any code, 
frameworks, or SDKs that fall in line with the functionality described above before submitting the next update 
for your app for review.Best regards,App Store Review
