ios上传过程中，Apple检测总是说app有如下问题，不知道何处有问题？？？以下是APPLE的回复

Hello, Thank you for your response. The code referenced in our initial rejection message is designed explicitly with the capability to change your app’s behavior or functionality after it has been approved to the App Store. 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 is considered not appropriate and needs to be removed from your app’s binary. Even if the code is not intended to be malicious, the security risks it poses to users is significant. To ensure your users are protected, perform an in-depth review of your app and remove any code, frameworks, or SDKs that facilitate the functionality outlined above. Best regards, App Store Review
