在Swift中初始化NSWindowController对象的正确方法是什么？

Question

尽我所能，我无法在这里得到语法。我做错了什么？

class MainWindowController: NSWindowController {

    let myThing: Thing

    override convenience init ( window: NSWindow! ) {
        myThing = Thing()
        self.init( windowNibName: "nibText" )
    }

    ...
}

非常感谢提前！

1. myThing = Thing()可以放置在声明属性的位置
2. 您应致电super.init
3. 您还需要实施init?(coder: NSCoder)，Xcode会很乐意为此插入模板
4. 您很可能需要另一个可以加载笔尖的初始化程序：

这样的事情：

class MainWindowController: NSWindowController {

    // the type of myThing will be inferred by the compiler
    let myThing = Thing()

    init() {
        super.init(window: nil)
        // load the contents of the nib, and set the owner as self, which connects the oultlets
        NSBundle.mainBundle().loadNibNamed("nibText", owner: self, topLevelObjects: nil)
    }

    // you might no longer need this intializer
    override init(window: NSWindow!) {
        super.init( window: window )
    }

   // ...
}
