今天跟大神又学习了些关于IOS开发Swift语言的外部参数和内部参数

 

func doSomething(num1: Int, num2: Int) -> Int {    return num1 + num2}doSomething(1, 2)class A {    func foo(#num1: Int, num2: Int) {        }        func objectAtIndex(num: Int forArray array: Int) {        }}var a = A()a.foo(num1: 1, num2: 12)a.objectAtIndex(12, forArray: 12)
