swift uiview 没有名为 center 的成员，无法转换为 UIView

Question

我创建了一个 de 模型数组 class 'fish' 并希望在我的视图加载时显示在视图上。我收到错误消息：

'Fish' 没有名为 'center' 的成员 'Fish' 不能转换为 'UIView'

请看下面我的代码。我将不胜感激任何帮助。谢谢

这是我的习惯 class:

class Fish {
var imageView = UIImageView(image: UIImage(named: "fish_3"))
}

这是我的视图控制器：

class ViewController: UIViewController {

var fishes:[Fish] 

required init(coder aDecoder: NSCoder) {
    fishes = [Fish]() 

    var fish3 = Fish()
    fish3.imageView = UIImageView(image: UIImage(named: "fish_3"))
    fishes.append(fish3)

    super.init(coder: aDecoder)
}

override func viewDidLoad() {
    super.viewDidLoad()

    for fish in fishes {
    var x = CGFloat(arc4random_uniform(120))
    var y = CGFloat(arc4random_uniform(200))
    fish.center.x = CGPoint(x: x, y: y)
    view.addSubview(fish)
    }   
}

Answer 1

fish.imageView.center = CGPoint(x: x, y: y)
view.addSubview(fish.imageView)

Answer 2

Fish 应该以某种方式从 UIView 继承，最好的方法是使其成为 UIImageView 的子类

class Fish: UIImageView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        // Setup
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        // Setup
    }
}

现在当你初始化它时：

var fish3 = Fish(frame: CGRectMake(0, 0, 50, 50))
fish3.image = UIImage(named: "fish_3")
fishes.append(fish3)

swift uiview 没有名为 center 的成员，无法转换为 UIView

swift uiview does not have a member named center and not convertible to UIView
