我正在制作 map
在info.plist中添加两个变量“隐私 - 位置何时使用描述”、“隐私 - 位置始终使用描述”
错误: 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因:“无效区域”
我的代码:
import UIKit
import MapKit
class ViewController: UIViewController, CLLocationManagerDelegate {
@IBOutlet weak var map: MKMapView!
var manager: CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
let uilpgr = UILongPressGestureRecognizer(target: self, action:Selector(("action:")))
uilpgr.minimumPressDuration = 2.0
map.addGestureRecognizer(uilpgr)
}
func action(gestureRecognizer:UIGestureRecognizer){
if gestureRecognizer.state == UIGestureRecognizerState.began{
let touchPoint = gestureRecognizer.location(in: self.map)
let newCoordinate = self.map.convert(touchPoint, toCoordinateFrom: self.map)
let annotation = MKPointAnnotation()
annotation.coordinate = newCoordinate
annotation.title = "Meu lugar"
self.map.addAnnotation(annotation)
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0]
let latitude = userLocation.coordinate.latitude
let longitude = userLocation.coordinate.longitude
let coordinate = CLLocationCoordinate2DMake(longitude,latitude)
let latDelta: CLLocationDegrees = 0.01
let lonDelta: CLLocationDegrees = 0.01
let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
let region:MKCoordinateRegion = MKCoordinateRegionMake(coordinate, span)
self.map.setRegion(region, animated: false)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
最佳答案
我认为您忘记导入 CoreLocation 框架。我认为您没有从委托(delegate)方法中获得有效的位置对象。请导入CoreLocation框架并再次测试。
