Hey guys, I'm fairly new to cocoa development here, so please bear with me. Is it possible to replace an object with another object so that all pointers to that object now point to the new object? In other words: Ptr A -> object1 Ptr B -> object1 Ptr C -> object1
I want to replace object1 with another object (of the same type), so that all my pointers now point to object2. I realize that I could manually replace all of the internal data in the object, thus leaving the pointer intact, but I was hoping that there would be an easier way. The reason I'm trying to do this is that I have a number of NSMutableArray's throughout my application whose contents are based off a database on a server. Periodically, the user searches the database, which returns a list of objects. Some of these objects the client already has, and in that case I would like to replace the local object with the one I've created via the server. I've implemented an NSDictionary that holds all of the objects that have come in from the server, and each NSMutableArray points to those same objects (they are all subsets of the main list). This works fine except for in the case where an existing object comes in from the server. I'd like to be able to replace the original object with my new one and retain all of it's pointers.
