Passing parameters to the method called by a NSTimer

Question

How can I pass a parameter to the method called by a NSTimer? My timer looks like this:

[NSTimer scheduledTimerWithTimeInterval:4 target:self selector:@selec         


        

Answer 1

For Swift 4.0:

You can have a function with any parameters you want and use the "scheduledTimer" block to execute the code you need to repeat.

func someFunction(param1: Int, param2: String) {

    let timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { timer in
        print(param1)
        print(param2)
    }
}

Be careful to call timer.invalidate() when you finish to prevent it from running continuously.
