添加手势识别器以允许在Swift中的MapView上水平滑动

let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:)))
mapView.addGestureRecognizer(panGesture)

@objc func handlePan(_ gestureRecognizer: UIPanGestureRecognizer) {
    let translation = gestureRecognizer.translation(in: mapView)
    
    if gestureRecognizer.state == .changed {
        // 根据手势的水平位移调整地图的中心点
        let newCenter = CGPoint(x: mapView.center.x + translation.x, y: mapView.center.y)
        mapView.center = newCenter
    }
    
    gestureRecognizer.setTranslation(CGPoint.zero, in: mapView)
}

mapView.isUserInteractionEnabled = true
