Swift学习 接口的创建与使用

import Foundation

//接口的定义关键字 protocol
protocol People{
func getname()->NSString
func getage()->Int
}

//实现相应该接口
class man :People {
var name:NSString!=""
var age:Int!=0
init(){
name="";age=0;
}

func setname(myname:NSString){
name = myname
}
func setage(myage:Int){
age = myage
}

func getname()->NSString{
return name
}
func getage()->Int{
return age
}
}

var myman = man();

myman.setname("myman test")

println(myman.getname())
