我可以在初始化器中使用其他初始化器吗?
class Car {
var manufacturer:String?
var speed:Int?
init (manufacturer manf:String){
manufacturer = manf
}
init(manufacturer manf:String, speed spd:Int){
manufacturer = manf // How can I use the other initializer here?
speed = spd
}
}
var b = Car(manufacturer: "bmw")
var k = Car(manufacturer: "kia", speed: 30)
最佳答案
我想到了。我只需要convenience
在我的辅助init
之前,然后可以使用self.init
调用原始的init
class Car {
var manufacturer:String?
var speed:Int?
init (manufacturer manf:String){
manufacturer = manf
}
convenience init(manufacturer manf:String, speed spd:Int){
self.init(manufacturer: manf)
speed = spd
}
}
