所以我創建了一個應用程序,當點擊一個按鈕時,用戶當前的位置被用來在Apples mapkit上創建一個註解。除了將按鈕鏈接到將創建註釋並在地圖上顯示註釋的代碼之外,我所做的一切工作。貝婁是我到目前爲止的代碼:單擊按鈕時,如何使用用戶當前位置顯示註釋?
import UIKit
import CoreLocation
import MapKit
class ViewController: UIViewController, CLLocationManagerDelegate {
var locationManager = CLLocationManager()
@IBOutlet var Map: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!) {
println("Updating Location \(newLocation.coordinate.latitude) , \(newLocation.coordinate.longitude) ")
let span = MKCoordinateSpanMake(0.0009, 0.0009)
let region = MKCoordinateRegion(center: newLocation.coordinate, span: span)
Map.setRegion(region, animated: false)
}
}
正如你所看到的,我有它,所以它不斷地顯示了他們的用戶。我想要這個,但我也希望用戶能夠創建註釋。
我的問題是我需要什麼代碼來創建註釋,它到底在哪裏?我對編程相當陌生,所以我不完全全面地使用所有的代碼術語,所以如果你願意的話(請爲我省下一些麻煩)。另外,當用戶單擊添加註釋的按鈕時,最後一個註釋需要被刪除。我將如何做到這一點?我在Xcode中使用Swift。
好了,這裏是我的: –
進口的UIKit 進口CoreLocation 進口MapKit 類的ViewController:UIViewController中,CLLocationManagerDelegate { VAR的LocationManager添加= CLLocationManager(CLLocationManager爲) //新代碼 var註解= MKPointAnnotation() // @IBOutlet var Map:MKMapView! 重寫func viewDidLoad(){ super.viewDidLoad() //在加載視圖後,通常從一個筆尖執行任何其他設置。 locationManager.delegate =自 locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation() } –
倍率FUNC didReceiveMemoryWarning(){ super.didReceiveMemoryWarning() //處置,可以被重新創建任何資源。 (更新位置\(newLocation.coordinate.latitude),\(newLocation.coordinate。)(位置更新位置\(newLocation.coordinate.latitude),\(newLocation.coordinate.laordinate。)(012LX} 函數locationManager(manager:CLLocationManager !, didUpdateToLocation newLocation:CLLocation !, fromLocation oldLocation:CLLocation!){ println經度)「) //新的代碼添加 newLocation.coordinate.latitude newLocation.coordinate.longitude 讓跨度= MKCoordinateSpanMake(0.0009,0.0009) –
