swift 静态方法

java 里面的静态方法和swift里面的类方法是一个意思

import Foundation

class Student{
func sayHi()
{

}

}

class Persion:Student{

var _name:String

init(name:String) {
self._name = name
}

override func sayHi() {
print("say \(self._name)")
}

class func sayHello(){
print("hello liaojianguo")
}
}

var student = Student()
student.sayHi()

var persion = Persion(name: "yihong")
persion.sayHi()
Persion.sayHello()
