NSTimer requiring me to add it to a runloop

Question

I am wondering if someone can explain why dispatching back to the main queue and creating a repeating NSTimer I am having to add it to RUN LOOP for it too fire?

Answer 1

You could always use this method instead:

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:3 target:self selector:@selector(getBusLocation) userInfo:nil repeats:YES];

This will save you a line, as it will add it to the run loop automatically.
