我有一個模擬移動到座標的GPX。我無法讓CLCircularRegion開火。我試圖把代碼放在任何地方。以下是我正在使用的內容：CLCircularRegion didEnterRegion不起作用
var center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(37.33171100, -122.03018400)
var radius: CLLocationDistance = CLLocationDistance(300)
var identifier: String = "Destination"
let region = CLCircularRegion(center: center, radius: radius, identifier: identifier)
manager!.startMonitoringForRegion(region)
我已將此放置到處。我已經把這個在：
viewDidLoad
viewWillAppear
viewDidAppear
mapViewDidFinishLoadingMap(mapView: MKMapView!
mapViewDidFinishRenderingMap(mapView: MKMapView!, fullyRendered: Bool)
locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)
這裏是我的GPX文件：
<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode">
<wpt lat="37.331711" lon="-122.030184">
<name>Apple</name>
</wpt>
<wpt lat="37.422455" lon="-122.084306">
<name>Google</name>
</wpt>
</gpx>
Println作品didStartMonitoringRegion並打印區域的信息到日誌，但它不火。似乎沒有任何工作，它使我瘋狂。這是我的完整程序。
import UIKit
import CoreLocation
import MapKit
class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {
var mapView: MKMapView?
var manager: CLLocationManager?
override func viewDidLoad() {
super.viewDidLoad()
mapView = MKMapView(frame: CGRectMake(0.0, 0.0, view.frame.size.width, view.frame.size.height))
self.mapView!.delegate = self
mapView!.showsUserLocation = true
view.addSubview(mapView!)
}
func locationManager(manager: CLLocationManager!, didEnterRegion region: CLRegion!) {
println("Entered")
}
func locationManager(manager: CLLocationManager!, didStartMonitoringForRegion region: CLRegion!) {
println("Monitoring")
println(region)
}
func mapViewDidFinishLoadingMap(mapView: MKMapView!) {
manager = CLLocationManager()
manager!.delegate = self
manager!.desiredAccuracy = kCLLocationAccuracyBest
manager!.startUpdatingLocation()
var center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(37.33171100, -122.03018400)
var radius: CLLocationDistance = CLLocationDistance(300)
var identifier: String = "Destination"
let region = CLCircularRegion(center: center, radius: radius, identifier: identifier)
manager!.startMonitoringForRegion(region)
}
}
