这是我从 Crashlytics
获得的崩溃日志

我在 AppDelegate
中使用 CLLocationmanage
r 以便在应用唤醒位置更新时获取用户的位置。
import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
import Quickblox
import Fabric
import Crashlytics
import CoreLocation
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {
var window: UIWindow?
var locationManager: CLLocationManager!
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if var options = launchOptions {
if var _: NSNumber = options[UIApplicationLaunchOptionsLocationKey] as? NSNumber {
locationManager.startUpdatingLocation()
}
}
initLocationManager()
return true
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let lat = manager.location?.coordinate.latitude,
let long = manager.location?.coordinate.longitude {
//sends to server to update
updateloc(String(lat), long: String(long))
}
}
func initLocationManager() {
if (nil == locationManager) {
locationManager = CLLocationManager()
}
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
if #available(iOS 9.0, *) {
locationManager.allowsBackgroundLocationUpdates = true
}
let status = CLLocationManager.authorizationStatus()
if (status == CLAuthorizationStatus.AuthorizedAlways || status == CLAuthorizationStatus.AuthorizedWhenInUse) {
locationManager.startUpdatingLocation()
}
}
可以帮我出一个吗?
谢谢。
最佳答案
您需要先调用 initLocationManager()
,然后才能在 locationManager.startUpdatingLocation()
中使用它。
尝试
if var options = launchOptions {
if options[UIApplicationLaunchOptionsLocationKey] != nil {
initLocationManager()
locationManager.startUpdatingLocation()
}
}
关于ios - CoreLocation 为空,应用程序在启动时崩溃,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/37107644/
