示例代碼:
class Drinking: NSObject{
class func drink(name:String) -> Drinking?{
var drink: Drinking?
switch name {
case "Coke" : drink = Coke(name: name)
case "Beer" : drink = Beer(name: name)
default :break;
}
return drink
}
}
class Coke:Drinking {
var name:String
init(name: String) {
self.name = name
}
}
class Beer:Drinking {
var name:String
init(name: String) {
self.name = name
}
}
let coke = Drinking.drink(name: "Coke") as! Coke
print(coke.name)
運(yùn)行結(jié)果:
Coke
