如何在iPhone上初始化NSObject的子类？

import Foundation

class MyClass: NSObject {
    // 在这里添加您的属性和方法
}

let myObject = MyClass()

class MyClass: NSObject {
    let someProperty: String

    init(someProperty: String) {
        self.someProperty = someProperty
        super.init()
    }
}

let myObject = MyClass(someProperty: "Hello, World!")

class MyClass: NSObject {
    let someProperty: String

    init(someProperty: String) {
        self.someProperty = someProperty
        super.init()
    }

    convenience init() {
        self.init(someProperty: "Hello, World!")
    }
}

let myObject = MyClass()
