我尝试在点击手势开始和结束时添加动作,但它不起作用!并在示例代码下方。

@State private var opacity = 1.0

var body: some View {
Image(systemName: "plus.square.on.square")
            .opacity(opacity)
            .onTapGesture {
                opacity = 0.2
            }
            .gesture(
            TapGesture()
                .onEnded({ _ in
                    opacity = 1.0
                })
            )
}
