multithreading - On what thread does a method initiated by NSTimer run on? -


when method amethod runs result of nstimer so:

nstimer* thetimer = [nstimer scheduledtimerwithtimeinterval: 1.0                                                       target: self                                                     selector: @selector(amethod:)                                                     userinfo: nil                                                     repeats: yes];

does amethod run on thread thetimer called (the main thread), or on separate thread? also, nstimer continue repeating while amethod running, or wait until amethod has finished?

nstimer calls selector passed in selector: parameter on thread timer scheduled. may or may not main thread.
