Yes. Most non-thread-safe objects don’t care what threads you call them on, so long as they’re only called on one thread at a time. So you can use locks or @synchronized blocks to coordinate access. (The exceptions are higher-level things that use runloops or dispatch queues, such as NSURLConnection, NSStream, etc. Those usually need to be called only from the same thread/queue they’re scheduled on, because they’re also getting callbacks on that same thread/queue.) —Jens _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
