Hi I am very close to implementing write (finally!!). Just one thing stopping me. When I do a save operation, I get this message in the writeToFile method
*** -[GMDataBackedFileDelegate longValue]: unrecognized selector sent to instance 0x16cb30f0 I am using an implementation similar to the one in LoopbackFS and assigning an NSNumber to the fileDelegate property when a file is created. I understand that this would happen if the value for fileDelegate was not retained. Or is there some other problem? Thanks.
