Ios “错误”；EXC坏访问”；在Swift中使用子类

我制作了3个文件

GameViewController

，

GameView

，

GameItemView

，但是如果

GameItemView

继承了

GameView

出现EXC错误访问错误

就像下面的代码

class GameViewController: UIViewController {

    var gameView: GameView!

    override func viewDidLoad() {
        super.viewDidLoad()

        gameView = GameView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height:     568))
        self.view.addSubview(gameView)
        gameView.gameViewController = self

    }

//....

}

class GameView: UIView {

    weak var gameViewController: GameViewController! //when GameViewController will appear, BAD ACCESS error     appear and stop here

    weak var gameItemView: GameItemView!

    override init(frame: CGRect) {

        super.init(frame: frame)

        gameItemView = GameItemView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width,     height: 568))
        self.addSubview(gameItemView)
    }
    //....

}

class GameItemView: GameView {    

    override init(frame: CGRect) {

        super.init(frame: frame)

        //add some views
    }
//...

}     

我以前在

GameView

上写过一些

GameItemView

的代码。但是

GameView的

代码太长了，所以我把其中的一部分移到了

GameItemView

。但随后错误出现了。我怎样才能解决它

更新：

我将在出错的地方添加代码。对不起，我忘记写了

var gameGameViewController: GameViewController!

为什么要从

GameView

继承

gameviewItem

？如果您想这样做，那么为什么要像上面那样编码，从而导致对

GameViewItem

&

GameView

的

init

进行递归调用。请将

GamveViewItem

的父类更改为

UIView

或其他类型，或者中断由

init

引起的递归模式

GameView

的初始化

override init(frame: CGRect) {
    super.init(frame: frame)
    // Here you're calling GameItemView's init, now go to GameItemView's init 
    gameItemView = GameItemView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 568))
    self.addSubview(gameItemView)
}

override init(frame: CGRect) {
    // You're calling GameView's init here and it goes back to 
    // there and then this keep on happening
    super.init(frame: frame)

    //add some views
}

GameItemView

的初始化

override init(frame: CGRect) {
    super.init(frame: frame)
    // Here you're calling GameItemView's init, now go to GameItemView's init 
    gameItemView = GameItemView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 568))
    self.addSubview(gameItemView)
}

override init(frame: CGRect) {
    // You're calling GameView's init here and it goes back to 
    // there and then this keep on happening
    super.init(frame: frame)

    //add some views
}

试试这个：

class GameViewController: UIViewController {

var gameView: GameView!

override func viewDidLoad() {
    super.viewDidLoad()
    gameView = GameView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 568))
    self.view.addSubview(gameView)
    gameView.gameViewController = self

    }

     //....

}

class GameView: UIView {

var gameViewController = GameViewController()
var gameItemView = GameItemView()
override init(frame: CGRect) {

    super.init(frame:frame)
   gameItemView = GameItemView.init(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 568))
    self.addSubview(gameItemView)
}

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

}

class GameItemView: UIView {

override init(frame: CGRect) {
    super.init(frame: frame)
    //add some views
 }

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

}

添加一个异常断点并运行代码。它会指向导致撞车的线路。然后您可以从

GameView

中研究如何解决itremove变量

gameItemView

。或者，如果需要，则不要将

GameView

继承到

GameItemView

中，因为该错误是在哪一行发生的？视图不应该知道它在哪个viewcontroller中in@gowtham我更新了代码。请检查一下，非常感谢。我使用了您的代码，但如果GameView和GameItemView像“GameView.something（）”和“GameItemView.something=true”那样互相调用，则不会调用Denit。我尝试使用“弱变量gameItemView=gameItemView（）”，如果视图将消失gameView.gameItemView=nil，则不调用Denit。。。。
