Just a wild guess: The NSData object has an overhead of 16 bytes and the (overloaded/member?) sizeof() function returns the NET contents, not the total size which should be 16 bytes (the overhead) longer.
-----Urspr?ngliche Nachricht----- Von: sqlite-users-bounces at mailinglists.sqlite.org [mailto:sqlite-users-bounces at mailinglists.sqlite.org] Im Auftrag von Rooney, Joe Gesendet: Dienstag, 19. J?nner 2016 00:46 An: sqlite-users at mailinglists.sqlite.org Betreff: [sqlite] Retrieved Blob Data has 16 Byte Header or ? The process, working in iOS: * Retrieve an employee photo using web service call, encoded in Base64 string * Convert Base64 string to NSData object - 3245 bytes * Store NSData object to a Blob in SQLite - 3245 bytes * Retrieve Blob to NSData object - 3245 bytes * The retrieved data will not display. * In comparing the hex input and retrieved output, I find there are 16 bytes added to the head of the data and I'm 16 bytes short. * If I add the 16 bytes to the total when storing the data and then read back 3245 bytes at the location ptr + 16 bytes, I've got my proper data, which displays as normal. Anyone have any insights into this? _____________________________ Joseph Rooney Mobile Development Commscope, Inc.
