ios - Is there a way to figure out what thread an NSManagedObjectContext is on? -

my understanding of threads respect nsmanagedobjectcontext can execute core data fetch requests, deletes, etc., on thread created. there way check see thread nsmanagedobjectcontext created on, or if @ particular point of execution current thread of particular nsmanagedobjectcontext?

thanks!

that's not accurate. better contexts cannot used concurrently more 1 thread or queue. common approach dealing create different contexts each thread/queue. it's possible use performblock , performblockandwait methods use contexts on multiple threads while keeping context access single-threaded.

as result, contexts don't have notion of belonging thread or queue, nor threads have reference contexts created on them.

if follow approach of 1 context per thread or queue, need keep track of code run , use appropriate context. example when using gcd, create context specific dispatch queue, , use when you've used dispatch_async run on queue.

if want link context queue, use own data structure contexts whatever concurrency scheme you're using-- current nsoperationqueue, or dispatch queue, or nsthread, or whatever. needed, it's possibility if can't find better techniques.
