Question

我编写了一个使用设备位置的基本程序。我写了它，这是ViewController的基础知识

mHandler.removeCallbacks(job); 
mHandler.postDelayed(job, 3000);

在我的info.plist中，根据需要，我有这个：

override func viewDidLoad() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print("Location Updated")
    lat = String(format: "%f", locationManager.location!.coordinate.latitude)
    long = String(format: "%f", locationManager.location!.coordinate.longitude)
}

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print("Failed Loc: \(error)")
}

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    print("Auth Changed: \(status)")
}

我在模拟器上运行代码，它给了我

<key>NSLocationWhenInUseUsageDescription</key>
<string>uses loc</string>

然后我分离了模拟器的位置并打印

Failed Loc: Error Domain=kCLErrorDomain Code=0 "(null)"

应该如此。奇怪;但是，当我将其上传到我的ios设备上时，它会要求许可，然后我没有输出。输出没有错误，它甚至不会触发didChangeAuthorizationStatus

**编辑：这是ViewController文件的标题：

Location Updated

**编辑2：

import CoreLocation

class Central_ViewController: UIViewController, UIScrollViewDelegate, UITabBarDelegate, CLLocationManagerDelegate {

    let locationManager = CLLocationManager()

打印

self.locationManager.requestWhenInUseAuthorization()
    if(CLLocationManager.locationServicesEnabled()) {
        print("Location Services Enabled")
        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
        self.locationManager.startUpdatingLocation()
    }else {
        print("Location Services NOT Enabled") // This needs to be completed to produce an error
    }

但它仍然不会更新位置，也不会产生错误。

首先，您应该检查NSLocationWhenInUseUsageDescription是否在相应的Info.plist中，即应用的那个。这是因为项目中有很多Info.plists，甚至GoogleMaps框架都有一个。

一旦正确的Info.plist包含NSLocationWhenInUseUsageDescription，您会注意到应用会提示您允许获取位置。

然后不要使用locationServicesEnabled来检查是否允许使用位置服务。请改用以下内容，以检查授权：

if CLLocationManager.authorizationStatus == .NotDetermined {
    self.locationManager.requestWhenInUseAuthorization()
}
self.locationManager.startUpdatingLocation()

CLLocationManager不在设备上工作
