How to parse the Manifest.mbdb file in an iOS 5.0

问题:

I have a backup I made with iOS 5 beta2 (with iTunes 10.5 beta also). But to my surprise, it doesn't contain an mbdx file.

The mbdb file looks same as previous format. How can I match the file ID and file name without Manifest.mbdx?

回答1:

The hex file name in the backups folder is the SHA hash of the file path appended to the domain, with a "-" in between. So the hash of "DomainName-/path/filename.png" will match to the correct file.

NOTE: App files have their domains prefixed with AppDomain-, like AppDomain-com.supercrazyawesome.myapp. Make sure you include that full string when calculating the SHA hash.
