我目前正在使用GeoFencing，我能够借助Apple提供的CoreLocation框架创建GeoFence。但是当应用启动时，我无法创建20个以上的围栏。这是我的代码
提前致谢
func createGeofence() {
if CLLocationManager.isMonitoringAvailable(for: CLCircularRegion.self) {
// region data
let title = "Verity's"
let coordinate = CLLocationCoordinate2DMake(17.4220382049842 , 78.3794177044913)
let regionRadius = 150.0
// setup region
let region = CLCircularRegion(center:CLLocationCoordinate2D(latitude: coordinate.latitude, longitude: coordinate.longitude), radius: regionRadius, identifier: title)
//Added monitoring
locationManager.startMonitoring(for: region)
}
else {
}
func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
self.enterRegion = region
}
func locationManager(_ manager: CLLocationManager, didExitRegionregion: CLRegion) {
}
最佳答案
var locationManager = CLLocationManager()
@IBAction func didTapOnSaveGeoFences(_ sender: AnyObject) {
let region = self.region(withGeotification: CLLocationCoordinate2D(latitude: (myLocation?.latitude)!, longitude: (myLocation?.longitide)!), radius: CLLocationDistance(myLocation!.distance),identifier: "\(myLocation?.locationID)", entry: true)
locationManager.startMonitoring(for: region)
}
func region(withGeotification coordinate: CLLocationCoordinate2D, radius: CLLocationDistance, identifier: String, entry: Bool) -> CLCircularRegion {
// 1
let region = CLCircularRegion(center: coordinate, radius: radius, identifier: identifier)
// 2
region.notifyOnEntry = entry
region.notifyOnExit = entry
return region
}
