我是Swift的新手,我需要获取用户的当前位置。我的意思是我需要得到纬度和经度。我试过这个:
class ViewController: UIViewController, CLLocationManagerDelegate{
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
CLGeocoder().reverseGeocodeLocation(manager.location, completionHandler: {(placemarks, error) -> Void in
if (error != nil) {
println("ERROR:" + error.localizedDescription)
return
}
if placemarks.count > 0 {
let pm = placemarks[0] as CLPlacemark
self.displayLocationInfo(pm)
} else {
println("Error with data")
}
})
}
func displayLocationInfo(placemark: CLPlacemark) {
// self.locationManager.stopUpdatingLocation()
println(placemark.locality)
println(placemark.postalCode)
println(placemark.administrativeArea)
println(placemark.country)
println(placemark.location)
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError) {
println("Error:" + error.localizedDescription)
}
}
在这里我可以获得坐标,但它看起来像:
1 + 55.75590390,+ 37.61744720> +/- 100.00米(速度-1.00 mps /航向-1.00)@ 2/14 / 15,10:48:14 AM莫斯科标准时间
如何只检索纬度和经度?
答案 0 :(得分:3)
为Swift 3.x和Swift 4.x更新了代码
我可以看到您在代码中使用了print(placemark.location)
。
因此,如果您只想获得纬度,请使用此代码
print(placemark.location.coordinate.latitude)
如果您只想获得经度,请使用此代码
print(placemark.location.coordinate.longitude)
希望这有帮助!

您可以预期多次拨打didUpdateLocations
的电话会随着时间的推移而提高准确性(假设您在GPS可以获得良好接收的本地电话 - 户外,不会被高楼包围)。您可以直接从locations
数组中的CLLocation对象访问纬度和经度。
let location = locations[locations.count-1] as CLLocation;
println("\(location.latitude) \(location.longitude)");
答案 2 :(得分:1)
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)
您的locations:[AnyObject]!
实际上是[CLLocation]
只需获取其最后一个对象并使用CLLocation的coordinate
属性。
