ios - 编写一组执行类似操作的轻击手势识别器的最 Eloquent 方式

Question

我有 9 个 View ，带有 9 个点击手势识别器，它们都执行非常相似的任务。我绞尽脑汁想用一种更 Eloquent 方式来写这篇文章，但一直想不出任何办法。任何帮助将不胜感激!

func flipToBack(){
    let matrix = Animations.HotSpotNumber(rawValue: currentHotSpot)
    guard let dict = matrix?.instructions else {return}
    flipLayerSecondPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func flipToFront(){
    let matrix = Animations.HotSpotNumber(rawValue: currentHotSpot)
    guard let dict = matrix?.instructions else {return}
    flipLayerSecondPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsFrontSide")
}


func handleBackSideTap(){
    let animation = Animations.HotSpotNumber(rawValue: currentHotSpot)
    guard let dict = animation?.instructions else {return}
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsFrontSide")
}

func handleHotSpotOneTap(){
    let dict = Animations.HotSpotNumber.One.instructions
    currentHotSpot = 1
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotTwoTap(){
    let dict = Animations.HotSpotNumber.Two.instructions
    currentHotSpot = 2
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotThreeTap(){
    let dict = Animations.HotSpotNumber.Three.instructions
    currentHotSpot = 3
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotFourTap(){
    let dict = Animations.HotSpotNumber.Four.instructions
    currentHotSpot = 4
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotSixTap(){
    let dict = Animations.HotSpotNumber.Six.instructions
    currentHotSpot = 6
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")

}

func handleHotSpotSevenTap(){
    let dict = Animations.HotSpotNumber.Seven.instructions
    currentHotSpot = 7
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotEightTap(){
    let dict = Animations.HotSpotNumber.Eight.instructions
    currentHotSpot = 8
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

func handleHotSpotNineTap(){
    let dict = Animations.HotSpotNumber.Nine.instructions
    currentHotSpot = 9
    flipLayerFirstPhaseWithInstructions(dict, layer: frontView.layer, directionOfTransformation: "towardsBackSide")
}

Answer 1

您可以创建一个接受几个参数来指定任务的函数(甚至是扩展)。然后，您无需为每个识别器编写整个函数，只需调用一个识别器并指定任务的参数即可。
