Swift学习 接口的创建与使用

importFoundation

//接口的定义关键字protocol

protocolPeople{

funcgetname()->Nsstring

funcgetage()->Int

}

//实现相应该接口

classman :People{

varname:Nsstring!=""

varage:Int!=0

init(){

name="";age=0;

}

funcsetname(myname:Nsstring){

name= myname

}

funcsetage(myage:Int){

age= myage

}

Nsstring{

returnname

}

Int{

age

}

}

varmyman =man();

myman.setname("myman test")

println(getname())

importFoundation

//接口的定义关键字protocol

protocolPeople{

Nsstring

Int

}

//实现相应该接口

People{

""

0

init(){

0;

}

Nsstring){

name= myname

}

Int){

age= myage

}

Nsstring{

name

}

Int{

age

}

}

man();

)
