有什么方法可以将MKMapView仅缩放到特定区域，同时禁用任何其他用户交互? [英] is there any way of allowing zooming MKMapView only to a specific region, while disabling any other user interaction?

问题描述

我有一个带有MapView的swift应用程序.这些是我在地图故事板上的设置:

I have a swift app with a MapView. These are my settings on story board for the map:

此外，在我正在执行的代码中:

Also, in the code I'm doing:

let regionRadius: CLLocationDistance = 10000
let initialLocation = CLLocation(latitude: latitude, longitude: longitude)
centerMapOnLocation(initialLocation, map: cell.mapView, radius: regionRadius)
cell.mapView.scrollEnabled = false
cell.mapView.rotateEnabled = false

我的方法centerMapOnLocation首先将地图居中放置在特定位置:

My method centerMapOnLocation centers the map initially on a specific location:

func centerMapOnLocation(location: CLLocation, map: MKMapView, radius: CLLocationDistance) {
    let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
                                                              radius * 2.0, radius * 2.0)
    map.setRegion(coordinateRegion, animated: true)
}

我只允许用户放大/缩小到确切的gps坐标.

I want to allow user only to zoom in/zoom out to the exact gps coordinates.

当前，用户无法滚动地图，但可以旋转地图-他可以在地图上的任意位置双击并在此处缩放.

Currently user cannot scroll the map, but he can rotate it, also - he can double tap wherever on the map and it will zoom there.

我想禁用这些选项并产生一种效果，即当用户双击地图(或捏合)时-它只会缩放到初始位置.

I want to disable those options and make an effect, that when user double taps the map (or pinch) - it will only zoom to the initial location.

我该怎么办?-rotateEnabled = false为什么不起作用?

How can I do it, and also - why does the rotateEnabled = false doesn't work?

推荐答案

在双击操作方法中添加以下代码

Add below code in double tap action method

var annotationPoint = MKMapPointForCoordinate(zoomToLocation.coordinate)
var zoomRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1)
mapView.setVisibleMapRect(zoomRect, animated: true)

在这里zoomToLocation是所需的CLLocation，而mapView是MKMapView的对象.

Here zoomToLocation is your desired CLLocation and mapView is MKMapView's object.

希望这可以解决您的问题:)

Hope this will solve your problem :)
