What is the difference between a timer and a scheduled timer in objective c?

Question

So I was making a timer, and I came across two different statements that I didn't know the difference between. Here is my code:

Mover = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(MoveDown) userInfo:nil repeats:YES];

What is the difference between that and:

Mover = [NSTimer timerWithTimeInterval:0.1 target:self selector:@selector(MoveDown) userInfo:nil repeats:YES];

Answer 1

Scheduled timers are automatically added to the run loop, unscheduled timers are not. The timer functionality is the same.
