Swift必须调用超类uiinputviewcontroller的指定初始值设定项 [英] Swift Must call a designated initializer of the superclass uiinputviewcontroller

问题描述

今天上午升级到8.3后，我在主题中收到错误。

I get the error in the subject after this morning's upgrade to 8.3.

以下代码用于完美运行，但不再编译。你们有没有人可以帮助我？

The code below used to work perfectly, however it doesn't compile anymore. Can any of you please help me?

protocol CustomAccessoryProtocol {
    func controlButtonPressed(tag:Int)
}

class CustomAccessory : UIInputViewController {
    var accessoryView : UIView!
    var delegate : CustomAccessoryProtocol!

    @IBOutlet weak var returnButton: UIButton!
    @IBOutlet weak var backButton: UIButton!
    @IBOutlet weak var forwardButton: UIButton!

    init(delegate: CustomAccessoryProtocol){
        super.init()
        self.delegate = delegate
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        fatalError("init(coder:) has not been implemented")
    }

    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
        let customNib = UINib(nibName: "CustomAccessory", bundle: nil)
        accessoryView = customNib.instantiateWithOwner(self, options: nil)[0] as! UIView
    }

    @IBAction func buttonPress(sender: AnyObject) {
        delegate.controlButtonPressed(sender.tag!)
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        view.addSubview(accessoryView)
    }
}

推荐答案

我在下面的代码中遇到了与NSWindowController相同的问题：

I had the same problem on the following code with NSWindowController:

init() {
    super.init()
}

我将其更改为：

convenience init() {
    self.init()
}

我认为Apple比以前更严格地执行便利性。

I'm thinking that Apple is enforcing convenience inits more strictly than before.
