Swift UIButton 中的 3D Touch Force 值

Question

如何测量应用于 UIButton 功能的 3D 触摸力？我想用它来改变 swift 中 AVAudioPlayer 属性的音量。

Answer 1

您可以为所有 UIView classes \ subclass

使用识别 3D 触摸的东西

定制class

class customButton : UIButton{
    override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
        for touch in touches{
            print("% Touch pressure: \(touch.force/touch.maximumPossibleForce)");
        }
    }

    override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
        print("Touches End")
    }
}

而不是 UIButton Touch Observer (TouchUpInside \ TouchUpInside..) 只需使用上面的方法
这将适用于所有 UIView class

class customView : UIView ....//same code as above
