Hi all, Consider a Core Data app, with Employee and Department entities. The Employee entity has 'name' and 'number' attributes. Department has a to- many relationship to Employees. I need a tableview of departments, where one column should show the 'name' of the employee who's 'number' is 0.

I'm working my way through Apple's "Validating App Store Receipts", and I can extract all the data, compute the digest and compare it against the hash. But now I am stuck converting the OCTET_STRING_t for the bundle_id in the Receipt to an NSString so I can compare it against my applications Bun
