问题描述

我有一个按钮，当它被按下时，它会执行一些操作.但我想修改相同的 Button 以检测更长的按下时间，并执行一组不同的过程.如何修改此代码以检测长按?

I have a Button where when it gets pressed, it performs some actions. But I would like to modify the same Button to detect a longer press, and perform a different set of processes. How do I modify this code to detect a long press?

Button(action: {
              // some processes

            }) {
              Image(systemName: "circle")
                .font(.headline)
                .opacity(0.4)

            }
