Question

我有mapbox地图和几个按钮。问题是当用户双击任何按钮映射放大。如何禁用此功能？即使用户双击缩小，地图也会放大，然后缩小。我尝试但在iOS中我不知道如何，对于android我知道解决方案。当双击按钮地图放大并且按钮委托双击时，下面的代码不起作用...

let singleTap4 = UITapGestureRecognizer(target: self, action: #selector(MainViewController.tapPatrolaBtn))

    singleTap4.numberOfTapsRequired = 1
    singleTap4.numberOfTouchesRequired = 1

    patrolaButton.isUserInteractionEnabled = true
    patrolaButton.addGestureRecognizer(singleTap4)

    patrolaButton.addTarget(self, action: #selector(multipleTap(_:event:)), for: UIControlEvents.touchDownRepeat)


@objc func multipleTap(_ sender: UIButton, event: UIEvent) {
    let touch: UITouch = event.allTouches!.first!
    if (touch.tapCount == 2) {
    }
}

Answer 1

在这里你也需要处理双击手势。

如果您使用的是双击手势识别器，那么double tapevent将不会委托给mapbox地图，而mapbox zoom事件也不会调用

使用以下代码： -

button.addTarget(self, action: #selector(multipleTap(_:event:)), for: UIControlEvents.touchDownRepeat)

//Don't do in action
func multipleTap(_ sender: UIButton, event: UIEvent) {
    let touch: UITouch = event.allTouches!.first!
    if (touch.tapCount == 2) {
    }
}

Answer 2

我找到解决方案，点击按钮我运行此代码，因此它暂时禁用地图手势：

mapView.isZoomEnabled = false

DispatchQueue.main.asyncAfter(deadline: .now() + 0.6) {
 self.mapView.isZoomEnabled = true }

iOS swift双击手柄按钮和地图
