Swift 2 CLLocationManager错误更新

我用Swift 2将Xcode 6升级为Xcode 7测试版。我得到这个错误，我无法找到如何修复它，请帮助我。谢谢这是我的代码：

 func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location = locations.last as! CLLocation

    let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.map.setRegion(region, animated: true)
}

我得到了这个错误：

Objective-C方法“locationManager:didUpdateLocations:”由方法“locationManager（u:didUpdateLocations:）”提供与协议“CLLocationManagerDelegate”中的可选需求方法“locationManager（uu:didUpdateLocations:）”冲突。

您需要使用

@objc

属性标记类或方法。因此，要么：

@objc class MyManagerDelegate: NSObject, CLLocationManagerDelegate {

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
        ...
    }

}

或：

只是和你有同样的问题，改变

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject])

单击您的项目-转到构建阶段->将二进制文件链接到库并添加CoreLocation.framework

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

let locationManager = CLLocationManager()
var LatitudeGPS = NSString()
var LongitudeGPS = NSString()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    updateLocation()

func updateLocation() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    //self.locationManager.distanceFilter = 10
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {

    locationManager.stopUpdatingLocation() // Stop Location Manager - keep here to run just once

    LatitudeGPS = String(format: "%.6f", manager.location!.coordinate.latitude)
    LongitudeGPS = String(format: "%.6f", manager.location!.coordinate.longitude)
    print("Latitude - \(LatitudeGPS)")

}

这是我在xcode 7上运行的代码，我也必须清理我的代码（产品->清理）

我通过以下代码解决了这个问题：

//CLLocationManagerDelegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location:CLLocation = locations[locations.count-1] as! CLLocation 

    if (location.horizontalAccuracy > 0) {
        self.locationManager.stopUpdatingLocation()
        print(location.coordinate, terminator: "")
        updateWeatherInfo(location.coordinate.latitude, longitude: location.coordinate.longitude)
    }
}

AnyObject

是

CLLocation

的超类型。两者都应该可以工作。我知道，但是当我将它从[AnyObject]更改为[CLLocation]时，错误消失了。已经尝试过了，它可以工作，但是它在这一行给了我一个错误：

let location=locations.last as！CLLocation

说locations.last不能是CLLocation我通过执行

让location=locations.last as！来修复它！CLLocation我喜欢在斯坦福iOS课程中，保罗·赫加蒂（Paul Hegarty）抱怨“AnyObject”超类型，现在苹果在Swift 2中修复了它P
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

let locationManager = CLLocationManager()
var LatitudeGPS = NSString()
var LongitudeGPS = NSString()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    updateLocation()

func updateLocation() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    //self.locationManager.distanceFilter = 10
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {

    locationManager.stopUpdatingLocation() // Stop Location Manager - keep here to run just once

    LatitudeGPS = String(format: "%.6f", manager.location!.coordinate.latitude)
    LongitudeGPS = String(format: "%.6f", manager.location!.coordinate.longitude)
    print("Latitude - \(LatitudeGPS)")

}

//CLLocationManagerDelegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location:CLLocation = locations[locations.count-1] as! CLLocation 

    if (location.horizontalAccuracy > 0) {
        self.locationManager.stopUpdatingLocation()
        print(location.coordinate, terminator: "")
        updateWeatherInfo(location.coordinate.latitude, longitude: location.coordinate.longitude)
    }
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations.last as! CLLocation!
    manager.stopUpdatingLocation()
    let region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude), span: MKCoordinateSpan(latitudeDelta: 0.001, longitudeDelta: 0.001))
    mapView.setRegion(region, animated: true)
