Swift call class function or property by string

Question

I have this class

class Foo{
     public class func barFunction(){}
     public class func barFunction2(){}
     public class func barFunction3(){}
}


        

Answer 1

You can use NSTimer to call a selector once:

NSTimer.scheduledTimerWithTimeInterval(0, target: self, selector: Selector("barFunction"), userInfo: nil, repeats: false)

Another more elegant solution

Using closures and dictionary:

let options = [
    "bar1": { Foo.barFunction1() },
    "bar2": { Foo.barFunction2() },
    "bar3": { Foo.barFunction3() }
]

// Ways of calling the closures

options["bar2"]!()

options["bar1"]?()

let key = "bar3"
if let closure = options[key] {
    closure()
}
