首先,我是iOS开发新手,所以请不要向我解释Objective-C的例子。CLLocationManagerDelegate没有捕获事件
我的问题是:
我做了这个类:
import UIKit
import CoreLocation
class BeaconRadar: NSObject, CLLocationManagerDelegate {
var manager : CLLocationManager!
var region : CLBeaconRegion!
var seenError = false
var locationFixAchieved = false
var locationStatus = "Not Started"
init() {
super.init()
var major = CLBeaconMajorValue(10)
var uuid = NSUUID(UUIDString: "E2C56DB5-DFFB-48D2-B060-D0F5A71096E0")
var id = "test"
manager = CLLocationManager()
region = CLBeaconRegion(proximityUUID: uuid, major: major, identifier: id)
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestAlwaysAuthorization()
manager.startRangingBeaconsInRegion(region)
}
func locationManager(manager: CLLocationManager!, didRangeBeacons beacons: AnyObject[], inRegion region: CLBeaconRegion!){
if (locationFixAchieved == false) {
locationFixAchieved = true
println(beacons)
}
}
// If failed
func locationManager(_manager: CLLocationManager!, rangingBeaconsDidFailForRegion region: CLBeaconRegion!, withError error: NSError!){
manager.stopUpdatingLocation()
if (error) {
if (seenError == false) {
seenError = true
println("Error getting location")
}
}
}
// // authorization status
func locationManager(_manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus){
println("2")
var shouldIAllow = false
switch status {
case CLAuthorizationStatus.Restricted:
locationStatus = "Restricted Access"
case CLAuthorizationStatus.Denied:
locationStatus = "User denied access"
case CLAuthorizationStatus.NotDetermined:
locationStatus = "Status not determined"
default:
locationStatus = "Allowed Access"
shouldIAllow = true
}
NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
if (shouldIAllow == true) {
println("Location Allowed")
// Start location services
manager.startUpdatingLocation()
} else {
println("Denied access: \(locationStatus)")
}
}
}
和我的viewController是:
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
var location = BeaconRadar()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
我期待得到消息之一在授权状态的实现func中。 (BeaconRadar中的最后一个)。但我什么也没有。
如果我将实现在的viewController,而不是在新的类 所有这些方法(即:
class ViewController: UIViewController, CLLocationManagerDelegate {
.....
}
那么它会工作得很好...
我失去了东西?
