推荐答案
Bitcode 是指代码类型:发送到iTunes的LLVM Bitcode连接。这允许Apple使用某些计算来进一步重新优化应用程序(例如:可能缩小可执行文件大小)。如果Apple需要更改您的可执行文件,那么他们可以在没有上传新版本的情况下执行此操作。
Bitcode refers to to the type of code: "LLVM Bitcode" that is sent to iTunes Connect. This allows Apple to use certain calculations to re-optimize apps further (e.g: possibly downsize executable sizes). If Apple needs to alter your executable then they can do this without a new build being uploaded.
这不同于:
切片这是Apple根据设备的分辨率和体系结构为用户设备优化应用程序的过程。切片不需要Bitcode。 (例如:仅在5秒内包含@ 2x图像)
This differs from:Slicing which is the process of Apple optimizing your app for a user's device based on the device's resolution and architecture. Slicing does not require Bitcode. (Ex: only including @2x images on a 5s)
应用程序细化是切片,bitcode和按需资源的组合
App Thinning is the combination of slicing, bitcode, and on-demand resources
