Hello All, I have a strange problem with NSKeyedArchiver/Unarchiver. I have a very complex object graph that I want to be persistent, independently of my document objects, so I'm archiving it into the user's application support folder. The root object for the archive is a class called Network, which basically stores very little, but does store the "Hierarchy" for the object graph, which is basically just a 2D NSMutableArray (though it's a pretty big one). When I unarchive my Network root object, and initWithCoder gets called in the Network class, the Hierarchy seems fine -- I can iterate over the objects, posting relevant data, and everything looks good. However, once the Network is loaded into the application, iterating over the loaded Network Hierarchy gives an exc_bad_access error. I'm using the same routine to post the data, so nothing's changed there. The data that's causing the problem is a float* array, saved using encodeBytes:length:forKey, and decoded using decodeBytesForKey:returnedLength:, which is how I've saved a number of similar float* arrays in the Hierarchy. What I don't understand is how the Hierarchy can be fine at the end of the Network's initWithCoder method, but then get banjaxed somehow after that.
Any thoughts greatly appreciated. J.
