[英]App crashing after iOS 11.2.6 update
The code for my CLLocationManagerDelegate was working fine before the last iOS update, however now it is crashing with the error 'NSInternalInconsistencyException', reason: 'Delegate must respond to locationManager:didUpdateLocations:'
我的CLLocationManagerDelegate的代码在上次iOS更新之前运行良好,但是现在由于错误'NSInternalInconsistencyException', reason: 'Delegate must respond to locationManager:didUpdateLocations:'
而崩溃'NSInternalInconsistencyException', reason: 'Delegate must respond to locationManager:didUpdateLocations:'
This is the code for my delegate (note: start()
is called from my ViewController): 这是我的委托的代码(注意:从我的ViewController调用start()
):
class Location: NSObject, CLLocationManagerDelegate {
let locationManager = CLLocationManager()
func start() {
locationManager.delegate = self
if locationManager.responds(to: #selector(CLLocationManager.requestAlwaysAuthorization)) {
locationManager.requestAlwaysAuthorization()
} else {
startLocationUpdates()
}
}
func startLocationUpdates() {
locationManager.allowsBackgroundLocationUpdates = true
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.activityType = .automotiveNavigation
locationManager.startUpdatingLocation()
locationManager.requestLocation()
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == .authorizedWhenInUse || status == .authorizedAlways {
startLocationUpdates()
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
// snip
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
// snip
}
}
Not sure how you're initializing this class, setting delegates, etc., but this is the UserLocation
class that I use. 不确定如何初始化此类,设置委托等,但这是我使用的UserLocation
类。 Compare it to yours. 与您的比较。
import Foundation
import CoreLocation
var userLocation: UserLocation?
class UserLocation: NSObject, CLLocationManagerDelegate {
var launchLocationSet = false
override init() {
super.init()
setupLocationManager()
}
public var currentLocation: CLLocation!
private var locationManager = CLLocationManager()
private func setupLocationManager() {
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
locationManager.delegate = self
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
currentLocation = locations.last! as CLLocation!
if !launchLocationSet {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "updateLocation"), object: nil, userInfo: nil)
launchLocationSet = true
}
}
func currentLatitude() -> CLLocationDegrees {
return currentLocation.coordinate.latitude
}
func currentLongitude() -> CLLocationDegrees {
return currentLocation.coordinate.longitude
}
}
