问题
I just can get my CLLocationManager to authorise. (swift under ios8) I even add an explicit requestAlwaysAuthorization call (which I don't need with objC under ios7)
func finishLaunch() {
//ask for authorization
let status = CLLocationManager.authorizationStatus()
if(status == CLAuthorizationStatus.NotDetermined) {
self.locationManager.requestAlwaysAuthorization();
}
else {
self.startMonitoring()
}
...
}
the callback never gets anything but NotDermined and there is no UIAlertView shown to the user.
func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if(status == CLAuthorizationStatus.NotDetermined) {
println("Auth status unkown still!");
}
self.startMonitoring()
}
Am I doing it wrong? -- Feels like a bug to me but I'd like some feedback
回答1:
Keep in mind that NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription keys are now mandatory, so you should include that in your plist.
回答2:
The only thing that you have to do is to add the Key "NSLocationWhenInUseUsageDescription" to your app info.plist then make a CLLocationManager requestWhenInUseAuthorization method and call it in the viewDidLoad.

As it happens with my objC app as well -- the one I KNOW works fine under ios7 -- I figured it should be a OS bug and reported it: #17128352
