打印()的长参数会产生错误“表达式太复杂而无法解决”
我是新的Swift,当我想要构建此代码时遇到问题。 “表达太复杂,无法在合理的时间内解决;考虑将表达分解为不同的子表达式”。打印()的长参数会产生错误“表达式太复杂而无法解决”
我想我的方法来管理属性,当我想打印的东西是错误的,但我没有找到原因。
class Personne{ var name : String
var forename : String
init(name : String, forename:String) {
self.name = name
self.forename = forename
}
}
class UnilStudent : Personne{
var id : Int
var section : String
init(name :String, forename:String, id:Int, section:String) {
self.section = section
self.id = id
super.init(name:name, forename:forename)
}
func affiche() {
print("Unil student N°" + \(self.id) + " : " + \(self.name) + \(self.forename) + "\n" + \(self.section + "\n")}
}
class Assistants : UnilStudent{
var assistantship : String
init(name :String, forename:String, id:Int, section:String, assistantship : String){
self.assistantship = assistantship
super.init(name :name, forename:forename, id:id, section:section)
}
override func affiche() {
super.affiche()
print("Unil student N°" + \(self.id) + " : " + \(self.name) + " " + \(self.forename) + "\n from " + \(self.section) + "is a student assistant for" + \(self.assistantship) + "\n")}
func printid(){
print("L'id de " + \(self.name) + " " + \(self.forename) + " est " + \(self.id))
}
}
let Adrien = Assistants(name : "BOB", forename : "BOBBY", id : 12000000, section : "FDCA", assistantship : "ACT")
let Alice = UnilStudent(name: "Hapoka", forename : "Alice", id : 17000000, section : "HEC")
print(Adrien)
回答:
该问题与继承无关。 \(...)
为串内插和只能用于内部一个字符串,例如:
print("Unil student N°\(self.id) : \(self.name)\(self.forename)")
代替
print("Unil student N°" + \(self.id) + " : " + \(self.name) + \(self.forename))
