我似乎无法让我的CoreLocation在我的Today Extension上工作。我已经将CoreLocation框架添加到了我的今日扩展,并将必要的项添加到plist(NSLocationAlwaysUsageDescription)并添加了一个默认位置,但它仍然无效。我正在尝试将纬度打印到日志中。
我是iOS编程的新手,任何帮助都将不胜感激!见下面的代码↓↓↓
import Foundation
import UIKit
import NotificationCenter
import CoreLocation
class WidgetViewController: UIViewController, NCWidgetProviding, CLLocationManagerDelegate {
var latitude: Double?
var longitude: Double?
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view from its nib.
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy - kCLLocationAccuracyBest
manager.requestAlwaysAuthorization()
manager.startUpdatingLocation()
delay(1.0) {
print("\(self.latitude)")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)) {
// Perform any setup necessary in order to update the view.
// If an error is encountered, use NCUpdateResult.Failed
// If there's no update required, use NCUpdateResult.NoData
// If there's an update, use NCUpdateResult.NewData
completionHandler(NCUpdateResult.NewData)
}
// MARK: - Location Code
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print(locations)
//userLocation - there is no need for casting, because we are now using CLLocation object
var userLocation:CLLocation = locations[0]
latitude = (userLocation.coordinate.latitude)
longitude = (userLocation.coordinate.longitude)
CLGeocoder().reverseGeocodeLocation(userLocation, completionHandler: { (placemarks, error) -> Void in
if (error != nil) {
print(error)
} else {
if let p = placemarks?[0] {
var subThoroughfare:String = ""
if (p.subThoroughfare != nil) {
subThoroughfare = p.subThoroughfare!
}
print(p)
}
}
})
}
func delay(delay: Double, closure: ()->()) {
dispatch_after(
dispatch_time(
DISPATCH_TIME_NOW,
Int64(delay * Double(NSEC_PER_SEC))
),
dispatch_get_main_queue(),
closure
)
}
}

你可以做两件事:
