SwiftUI - 两指轻敲手势

Question

好吧，我一直在四处寻找谷歌，无法找到创建 OnTwoFingerTap 检测的好方法，如果有人可以帮助我请:) 我会很感激

所以在这个链接中有一个解决方案，它有错误： Error build: Reference to generic type 'UIViewRepresentableContext' requires

func makeUIView(context: UIViewRepresentableContext) -> UIView
{
    let view = UIView()
    let doubleTapGestureRecognizer = UITapGestureRecognizer(target: context.coordinator, action: #selector(Coordinator.handleTap(sender:)))
   
    /// Set number of touches.
    doubleTapGestureRecognizer.numberOfTouchesRequired = 2
   
    view.addGestureRecognizer(doubleTapGestureRecognizer)
    return view
}

func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext)
{
}

Answer 1

我通过将 UIViewRepresentContext 切换为 Context 来修复它

func makeUIView(context: Context) -> UIView
{
    let view = UIView()
    let doubleTapGestureRecognizer = UITapGestureRecognizer(target: context.coordinator, action: #selector(Coordinator.handleTap(sender:)))
   
    /// Set number of touches.
    doubleTapGestureRecognizer.numberOfTouchesRequired = 2
   
    view.addGestureRecognizer(doubleTapGestureRecognizer)
    return view
}

func updateUIView(_ uiView: UIView, context: Context)
{
}
