The zip file I uploaded is 19.5MB, but on the App Store, Apple reports it as 24.5MB -- too large for over-the-air downloading. Is Apple adding a 5MB wrapper? Decompressing and recompressing less efficiently? Using 815K "megabytes"?

推荐答案

来自 Apple:

当您的申请获得批准时苹果在 App Store 上销售，它是加密用于 DRM 目的和重新压缩.当加密是补充，压缩文件的大小将增加.的确切尺寸增加会因应用程序而异，但是，大小增加可以是大时二进制文件包含很多连续的零.我们无法保证您的文件大小之后已添加加密.

When your application is approved by Apple to sell on the App Store, it is encrypted for DRM purposes and re-compressed. When the encryption is added, the size of the compressed file will increase. The exact size of the increase will vary from app to app, however, the size increase can be large when the binary contains a lot of contiguous zeros. We are unable to guarantee the size of your file after the encryption has been added.
