创建一个对象
先写一个People类
//
// People.swift
// Class
//
// Created by YouXianMing on 15/3/18.
// Copyright (c) 2015年 YouXianMing. All rights reserved.
//
import Foundation
class People {
// 变量值
var name : String
var age : Int
// 初始化方法
init() {
name = "YouXianMing"
age = 10
}
// 类方法
class func maxAge() -> Int {
return 100
}
class func minAge() -> Int {
return 0
}
// 普通方法
func info(name : String, age : Int) -> String {
return "age:\(age) + name:\(name)"
}
func subInfo() -> String {
return "age:\(age) + name:\(name)"
}
}再写一个Student类继承至People类
//
// Student.swift
// Class
//
// Created by YouXianMing on 15/3/18.
// Copyright (c) 2015年 YouXianMing. All rights reserved.
//
import Foundation
class Student: People {
var score : Float
override init() {
score = 100.0
super.init()
}
}然后是控制器源码:
//
// ViewController.swift
// Class
//
// Created by YouXianMing on 15/3/18.
// Copyright (c) 2015年 YouXianMing. All rights reserved.
//
import UIKit
class ViewController: UIViewController {
// 初始化变量
var people : People
var studuent : Student = Student()
// 必要的初始化
required init(coder aDecoder: NSCoder) {
// 调用初始化方法
people = People()
people.name = "Y.X.M."
people.age = 20
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
println(people.info("YouXianMing", age: 28))
println(people.subInfo())
println(People.maxAge())
}
}一些需要注意的地方:
