苹果简化了我们的构建过程，所以你不需要每次都点击相同的复选框。你可以通过将这个标志编译到应用程序中来简化你的iTC流程。

截至2019年，情况仍然如此。

在plist文件中添加此密钥…一切都会好起来的。

<key>ITSAppUsesNonExemptEncryption</key>  
<false/>

只是在</dict></plist>之前粘贴

在Xcode 12中使用Non-Exempt Encryption而不是ITSAppUsesNonExemptEncryption

基本上有两件事要记住。如果你根本不使用加密，或者你是豁免规则的一部分，你才可以将它设置为NO。这适用于以下几种应用:
