Question

我的代码包含在下面。这是一个用于返回当前位置坐标的类。我得到的唯一输出是“之前之后” - 围绕requestAlwaysAuthorization的打印行。然后App崩溃了。请求对话框有时会短暂显示，有时会持续几秒钟。有几次我甚至按“OK”。应用程序总是崩溃。我在xCode 7.0和现在的xCode 7.0.1，iOS 9.0中遇到过这个问题。我已经搜索了StackOverflow的高低，关于这个主题的大多数问题都是针对xCode和iOS的早期版本，并且在我的案例中没有一个发布的解决方案有帮助。因此，这个问题。我还发现YouTube教程基本上就是我正在做的事情，但没有快乐。我的plist中也有NSLocationAlwaysUsageDescription，我有隐私 - 位置使用说明和NSLocationWhenInUseUsageDescription以获得良好的衡量标准。我也尝试通过Product \ Scheme菜单从xCode发送位置，我也尝试使用模拟器的Debug \ Location。我为每个尝试了几个不同的位置选项。模拟器的地图应用似乎总是有效。 Apple的LocateMe（用Objective C编写）也有效。 Swift 2（我的代码如下）失败。

import CoreLocation

class TheCurrentLocation: NSObject, CLLocationManagerDelegate {

    var locationManager: CLLocationManager!
    var latitude: Double = 0
    var longitude: Double = 0
    var locationStatus: NSString = "Not Started"

    func initialize() {

        self.locationManager = CLLocationManager()
        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
        print("before")
        self.locationManager.requestAlwaysAuthorization()
//        self.locationManager.requestWhenInUseAuthorization()
        print("after")

    } // END: initialize()

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {

        self.locationManager.stopUpdatingLocation()
        print("ERRORS: " + error.localizedDescription )

    } // END: locationManager delegate didFailWithError

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

        let location = locations.last
        let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
        self.locationManager.stopUpdatingLocation()
        print ("ta da")
        self.latitude = center.latitude
        self.longitude = center.longitude

    } // END: locationManager delegate didUpdateLocations

    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {

        var isAllowed = false

        switch status {
        case CLAuthorizationStatus.Restricted:
            locationStatus = "Restricted Access to Location"
        case CLAuthorizationStatus.Denied:
            locationStatus = "User Denied Access to Location"
        case CLAuthorizationStatus.NotDetermined:
            locationStatus = "Location Status Not Determined"
        default:
            locationStatus = "Allowed Access to Location"
            isAllowed = true
        } // END switch status

        if (isAllowed == true) {
            NSLog(String(locationStatus))
            self.locationManager.startUpdatingLocation()
        } else {
            NSLog(String(locationStatus))
        }

    } // END: locationManager delegate didChangeAuthorizationStatus

} // END: theCurrentLocation

Answer 1

我想我知道可能导致它的原因。您不能同时拥有NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription。只有其中一个。我想我之前遇到过这个问题。尝试删除其中一个并查看是否可以修复它。
