原型模式 Prototype Pattern

class BusinessCard:NSCopying{//實現Swift NSCopying介面
    init(name:String,age:String,company:Company) {
        self.name = name
        self.age = age
        self.company = company
    }
    var name:String
    var age:String
    var company:Company
    func printDetails() {
        print("公司 \(company.companyName) 公司地址 \(company.location) 姓名 \(name) 年齡 \(age) ")
       }
    //實現prototype原型模式的copy方法
    func copy(with zone: NSZone? = nil) -> Any {
        return BusinessCard(name: self.name, age: self.age, company: self.company.copy() as! Company)
    }
}
class Company:NSCopying{
    
    init(companyName:String,location:String) {
        self.companyName = companyName
        self.location = location
    }
    var companyName:String
    var location:String
    func copy(with zone: NSZone? = nil) -> Any {
        return Company(companyName: self.companyName,location: self.location)
    }
}
var businessCard1 = BusinessCard(name: "allen", age: "27", company: Company(companyName: "雄獅", location: "內湖"))
businessCard1.printDetails()
var businessCard2 = businessCard1.copy() as! BusinessCard
businessCard2.printDetails()
//變更複製內容
businessCard2.age = "8"
businessCard2.company = Company(companyName: "CMoney", location: "新埔")
businessCard2.printDetails()
