提醒iOS 9中的位置服務許可

Question

我已經在info.plist設置了NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription ，該警報在應用程序要使用位置服務時出現，但是該警報僅出現了一段時間，我無法單擊此警報。 該警報自動消失！

 func showLocation(sender: UIButton)
    {
        let manager = CLLocationManager()
        manager.delegate = self
        if CLLocationManager.authorizationStatus() != CLAuthorizationStatus.AuthorizedAlways
        {
            manager.requestWhenInUseAuthorization()
        }
        manager.startUpdatingLocation()
    }
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        for location in locations {
            print("The location is (location)")
        }
    }

Answer 1

self.locationManager = [[CLLocationManager alloc]init];
if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined)
{
    if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"] && [self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]){
        [self.locationManager requestWhenInUseAuthorization];
    }
}
else if([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied)
{
    //Location Services is off from settings

}
else if([CLLocationManager authorizationStatus] == kCLAuthorizationStatusRestricted)
{

}
