When you run NSTimer, the @selector method itself will determine wether you want to run in background or main thread.

Initial set up:

self.scanTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(manageMethod) userInfo:nil repeats:YES]; //@property (nonatomic, strong) NSTimer *scanTimer

Case you want to run in Background:

-(void)manageMethod
{
      dispatch_queue_t queue = dispatch_queue_create("com.mysite.thread1",NULL);
      dispatch_async(queue,^{ 
           //run in background
      });
}
