Question

我有这个动画来动画UIImageView：

datatable.controller.js

升级到Swift 3后，我开始收到以下错误：

override func deselectAnimation(_ icon : UIImageView, textLabel : UILabel, defaultTextColor : UIColor) {
    playMoveIconAnimation(icon, values:[icon.center.y + 4.0, icon.center.y])
    playDeselectLabelAnimation(textLabel)
    textLabel.textColor = defaultTextColor

    if let iconImage = icon.image {
        let renderImage = iconImage.withRenderingMode(.alwaysTemplate)
        icon.image = renderImage
        icon.tintColor = defaultTextColor
    }
}

func playMoveIconAnimation(_ icon : UIImageView, values: [AnyObject]) {

    let yPositionAnimation = createAnimation("position.y", values:values, duration:duration / 2)

    icon.layer.add(yPositionAnimation, forKey: "yPositionAnimation")
}

我在类似question中读到函数应该有返回值，但我不知道如何实现它。非常感谢您帮助解决此错误

Answer 1

如果您希望仅将CGFloat类型的值更改为：

func playMoveIconAnimation(_ icon : UIImageView, values: [CGFloat]) {

    let yPositionAnimation = createAnimation("position.y", values:values, duration:duration / 2)

    icon.layer.add(yPositionAnimation, forKey: "yPositionAnimation")
}

感谢Nirav D和Leo Dabus，我能够解决它，我没有解释，但这是最终有效的代码：

override func deselectAnimation(_ icon : UIImageView, textLabel : UILabel, defaultTextColor : UIColor) {
    playMoveIconAnimation(icon, values: [CGFloat(icon.center.y + 4.0)])
    playDeselectLabelAnimation(textLabel)
    textLabel.textColor = defaultTextColor

    if let iconImage = icon.image {
        let renderImage = iconImage.withRenderingMode(.alwaysTemplate)
        icon.image = renderImage
        icon.tintColor = defaultTextColor
    }
}

func playMoveIconAnimation(_ icon : UIImageView, values: [Any]) {

    let yPositionAnimation = createAnimation("position.y", values:values as [AnyObject], duration:duration / 2)

    icon.layer.add(yPositionAnimation, forKey: "yPositionAnimation")
}

没有'+'候选者在Swift 3中产生预期的上下文结果类型'AnyObject'错误
