ios – didUpdateLocations从未调用过

概述我正在尝试获取用户的位置.为此,我在info.plist中设置了以下属性： 我还在viewDidLoad方法中添加了以下代码以及下面的函数.问题是locationManager(manager,didUpdate ….)函数永远不会被调用,我也从未被提示访问位置的权限,即使我已经删除并再次安装了应用程序.我在iPad上测试,而不是在模拟器上测试. didFailWithError函数永远不会被调用 我正在尝试获取用户的位置.为此,我在info.pList中设置了以下属性：

我还在vIEwDIDLoad方法中添加了以下代码以及下面的函数.问题是locationManager(manager,dIDUpdate ….)函数永远不会被调用,我也从未被提示访问位置的权限,即使我已经删除并再次安装了应用程序.我在iPad上测试,而不是在模拟器上测试. dIDFailWithError函数永远不会被调用.

self.locationManager.delegate = self    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest    self.locationManager.requestWhenInUseAuthorization()    self.locationManager.startUpdatingLocation()func locationManager(manager: CLLocationManager,dIDUpdateLocations locations: [CLLocation]) {    print("UPDATING")    let locValue:CLLocationCoordinate2D = manager.location!.coordinate    let latitude = locValue.latitude    let longitude = locValue.longitude    latitudeText = "\(latitude)"    longitudeText = "\(longitude)"    if let a = latitudeText,b = longitudeText {        print(a)        print(b)        self.locationManager.stopUpdatingLocation()        if (userAlreadyExist()) {            dispatch_async(dispatch_get_main_queue(),{                //self.performSegueWithIDentifIEr("segueWhenLoggedIn",sender: self)                self.performSegueWithIDentifIEr("showCamera",sender: self)                // self.performSegueWithIDentifIEr("showTabbarController",sender: self)            })        }        else {            dispatch_async(dispatch_get_main_queue(),{                self.performSegueWithIDentifIEr("segueWhenLoggedOut",sender: self)            })        }    }}func locationManager(manager: CLLocationManager,dIDFailWithError error: NSError) {    print(error.localizedDescription)}

编辑：

我添加了以下代码片段：

if CLLocationManager.locationServicesEnabled() {        print("yes")    }    else {        print("no")    }

它返回是.我还检查了我的设备,locationServices已启用,应用程序已列在那里,但是所有其他应用程序都在其旁边写着“While Using”,“Never”或“Always”,我没有写任何东西.

解决方法 你在哪里开始更新位置？例如：

//location manager    lazy var locationManager: CLLocationManager = {        var _locationManager = CLLocationManager()        _locationManager.delegate = self        _locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters        _locationManager.activityType = .automotiveNavigation        _locationManager.distanceFilter = 10.0  // Movement threshold for new events        _locationManager.allowsBackgroundLocationUpdates = true // allow in background        return _locationManager    }()    if CLLocationManager.locationServicesEnabled() {                locationManager.startUpdatingLocation() // start location manager            }

这是一个工作的控制器代码：
设置自定义iOS目标属性也很重要.

将这两行添加到Info.pList：

NSLocationWhenInUseUsageDescription

NSLocationAlwaysUsageDescription
