我想使用Swift获取当前的纬度和纬度,并通过标签显示.我试图这样做,但标签上没有显示.
import UIKit
import CoreLocation
class ViewController: UIViewController,CLLocationManagerDelegate{
@IBOutlet weak var longitude: UILabel!
@IBOutlet weak var latitude: UILabel!
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
if (CLLocationManager.locationServicesEnabled()) {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
} else {
println("Location services are not enabled");
}
}
// MARK: - CoreLocation Delegate Methods
func locationManager(manager: CLLocationManager!,didFailWithError error: NSError!) {
locationManager.stopUpdatingLocation()
removeLoadingView()
if ((error) != nil) {
print(error)
}
}
func locationManager(manager: CLLocationManager!,didUpdateLocations locations: [AnyObject]!) {
var locationArray = locations as NSArray
var locationObj = locationArray.lastObject as CLLocation
var coord = locationObj.coordinate
longitude.text = coord.longitude
latitude.text = coord.latitude
longitude.text = "\(coord.longitude)"
latitude.text = "\(coord.latitude)"
}
}
IMHO,当您正在查找的解决方案非常简单时,您的代码过于复杂.
我已经通过使用以下代码：
首先创建一个CLLocationManager和请求授权的实例
var locManager = CLLocationManager()
locManager.requestWhenInUseAuthorization()
然后检查用户是否允许授权.
var currentLocation = CLLocation!
if( CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedWhenInUse ||
CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized){
currentLocation = locManager.location
}
使用它只是这样做
label1.text = "\(currentLocation.coordinate.longitude)" label2.text = "\(currentLocation.coordinate.latitude)"
您将它们设置为label.text是正确的,但我可以想到的唯一原因是用户没有给您权限,这就是为什么您的当前位置数据将为零.
但是,您需要调试并告诉我们.
另外CLLocationManagerDelegate也是没有必要的.
希望这有帮助.如果有疑问,请问
