Using NSTimer to fire a method on Previous Controller

Question

Lets say I have a ViewController1 and a ViewController2. I segued from VC1 to VC2. So I am in ViewController 2 and I want to use

[NSTimer scheduledTimerWithTimeInterval:10 target: selector: userInfo:nil repeats:NO]

to execute a method on ViewController1 (let's call it method1.) What are the parameters for NSTimer? Thanks

You want to schedule timer in the first Controller and that action to be executed in the next Controller?? — Karlo A. López, Jun 07 '15 at 16:03

Why are you trying to do this? I'd use a delegate (protocol) and let VC1 handle the timing in case VC2 is destroyed.

On segue:

VC2.delegate = VC1

On event:

self.delegate.firedEvent()

On VC1:

func firedEvent() {
    // delay here
}
