问题
We've been fighting to get our app under 20 MB so that over-the-air downloading would work, and with our last release 2 weeks ago we succeeded.
It took a bunch of trial-and-error to get right, but eventually we cut our app down to 27MB (uncompressed), which showed up in the store as 19.5MB.
All seemed well, until we did a minor code update to fix some bugs, when suddenly the app store version of the app ballooned to the full uncompressed 27MB size! I just checked the distribution archives, and the newer binary is actually 2k smaller than the older one.
Does anyone have any idea what would cause this?

In http://www.alexcurylo.com/blog/2010/05/22/tip-shipping-app-size/ there is a way to calculate the final size. In short:
- open the .app bundle via right-click -> Show Package Contents (on Mac)
- locate the executable file and remember its (uncompressed) size (Size “A”)
- delete the executable from the bundle
- zip the bundle and remember the bundle’s compressed size (Size “B”)
- Size “C” are the 100 KB from the additional files added to the bundle by Apple.
The final calculation for the maximum size of your App is as follows:
A + B + C = maximum size of your App after approval
in words:
(uncompressed executable size) + (app bundle compressed but without executable) + 0,1 MB = maximum size of your App after approval
