swift 3.0 基础练习 面向对象 类

class GirlFirend: NSObject {
    var name:String = ""
    var age :Int = 0
    
    //初始化随机姓名和年龄
    override init() {
        name = String(format: "%c%c%c", 65 + arc4random()', 65 + arc4random()', 65 + arc4random()')
        age = Int( arc4random() % 10 + 18 )
    }
    
    //重写描述方法
    override var description: String{
        return "姓名:\(name) \t,年龄:\(age)"
    }
    
    //约会方法
    func dataWith() {
        print("data with \(name),she is \(age)")
    }

//创建100个对象
for i in 0...99{
    var gF = GirlFirend()
    print(gF)
    gF.dataWith()    
}
