首先，当我设置区域地图视图时，放大和缩小工作正常。当我尝试使用自定义视图设置注释时，以及设置注释时，缩放不起作用。用户放大后，会自动缩小。MKMapview在swift中无法正常工作
见下面我的代码：
func setRegion(){
var newRegion = MKCoordinateRegion()
// let str = String(format: "%.01f", maxLoc)
// maxdist = Double(str)!
let subscriberData = (SubscriberConfigDBHandler.SubConfigDBSharedInstance).getSubscriberUserDetails()
let latLanCoords :CLLocation = CLLocation(latitude:subscriberData.busLat as Double , longitude:subscriberData.busLng as Double)
newRegion.center.latitude = latLanCoords.coordinate.latitude
newRegion.center.longitude = latLanCoords.coordinate.longitude
newRegion.span.latitudeDelta = 0.075
newRegion.span.longitudeDelta = 0.075
self.liveTrackingMapView.setRegion(newRegion, animated: false)
}
private var mapChangedFromUserInteraction = false
private func mapViewRegionDidChangeFromUserInteraction() -> Bool {
let view = self.liveTrackingMapView.subviews[0]
if let gestureRecognizers = view.gestureRecognizers {
for recognizer in gestureRecognizers {
if(recognizer.state == UIGestureRecognizerState.Began || recognizer.state == UIGestureRecognizerState.Ended) {
return true
}
}
}
return false
}
func mapView(mapView: MKMapView, regionWillChangeAnimated animated: Bool) {
mapChangedFromUserInteraction = mapViewRegionDidChangeFromUserInteraction()
}

你有没有仔细观察地图加载方法的语法和步骤..？ –
请包含一些代码。否则，我们基本上无法帮助你解决这个问题。 –
我已经正确设置了区域，位置坐标和代表，但是当我尝试缩放到某个位置时，它会缩小。 – Jalindar
