SwiftUI:如何处理轻敲和轻敲长按按钮? [英] SwiftUI: how to handle BOTH tap & long press of button?

问题描述

我在 SwiftUI 中有一个按钮，我希望能够对点击按钮"(正常点击/点击)和长按"执行不同的操作.

I have a button in SwiftUI and I would like to be able to have a different action for "tap button" (normal click/tap) and "long press".

这在 SwiftUI 中可行吗?

Is that possible in SwiftUI?

这是我现在拥有的按钮的简单代码(仅处理正常"点击/触摸情况).

Here is the simple code for the button I have now (handles only the "normal" tap/touch case).

Button(action: {self.BLEinfo.startScan() }) {
                        Text("Scan")
                    } .disabled(self.BLEinfo.isScanning)

我已经尝试添加长按手势"，但它仍然只执行"正常/短按"点击.这是我试过的代码:

I already tried to add a "longPress gesture" but it still only "executes" the "normal/short" click. This was the code I tried:

Button(action: {self.BLEinfo.startScan() }) {
                        Text("Scan")
                            .fontWeight(.regular)
                            .font(.body)
                        .gesture(
                            LongPressGesture(minimumDuration: 2)
                                .onEnded { _ in
                                    print("Pressed!")
                            }
                        )
                    }

谢谢！

推荐答案

我尝试了很多东西，但最终我做到了:

I tried many things but finally I did something like this:

    Button(action: {
    }) {
        VStack {
            Image(self.imageName)
                .resizable()
                .onTapGesture {
                    self.action(false)
                }
                .onLongPressGesture(minimumDuration: 0.1) {
                    self.action(true)
                }
        }
    }

仍然是一个有效果的按钮，只是短按和长按不同.

It is still a button with effects but short and long press are different.
