对于iOS-11 对于iOS 11，看看这个答案:iOS 11位置访问

需要在plist中添加两个键并提供如下图所示的消息:

 1. NSLocationAlwaysAndWhenInUseUsageDescription 
 2. NSLocationWhenInUseUsageDescription
 3. NSLocationAlwaysUsageDescription

对于iOS-10及以下版本:

NSLocationWhenInUseUsageDescription

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;
if([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]){
    [locationManager requestWhenInUseAuthorization];
}else{
    [locationManager startUpdatingLocation];
} 

委托方法

#pragma mark - Lolcation Update 
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [errorAlert show];
}
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    switch (status) {
        case kCLAuthorizationStatusNotDetermined:
        case kCLAuthorizationStatusRestricted:
        case kCLAuthorizationStatusDenied:
        {
            // do some error handling
        }
            break;
        default:{
            [locationManager startUpdatingLocation];
        }
            break;
    }
}
- (void)locationManager:(CLLocationManager *)manager
     didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations lastObject];
    userLatitude =  [NSString stringWithFormat:@"%f", location.coordinate.latitude] ;
    userLongitude =  [NSString stringWithFormat:@"%f",location.coordinate.longitude];
    [locationManager stopUpdatingLocation];
}

迅速的过程

遵循以下指示:

对于iOS-11 对于iOS 11，看看这个答案:iOS 11位置访问

需要在plist中添加两个键并提供如下图所示的消息:

 1. NSLocationAlwaysAndWhenInUseUsageDescription 
 2. NSLocationWhenInUseUsageDescription
 3. NSLocationAlwaysUsageDescription

对于iOS-10及以下版本:

import CoreLocation
class ViewController: UIViewController ,CLLocationManagerDelegate {
var locationManager = CLLocationManager()

//MARK- Update Location 
func updateMyLocation(){
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;
    if locationManager.respondsToSelector(#selector(CLLocationManager.requestWhenInUseAuthorization)){
       locationManager.requestWhenInUseAuthorization()
    }
    else{
        locationManager.startUpdatingLocation()
    }
}

委托方法

//MARK: Location Update
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    NSLog("Error to update location :%@",error)
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    switch status {
    case .NotDetermined: break
    case .Restricted: break
    case .Denied:
            NSLog("do some error handling")
        break
    default:
        locationManager.startUpdatingLocation()
    }
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
     let location = locations.last! as CLLocation
    var latitude = location.coordinate.latitude
    var longitude = location.coordinate.longitude

}

        // ** Don't forget to add NSLocationWhenInUseUsageDescription in MyApp-Info.plist and give it a string

        self.locationManager = [[CLLocationManager alloc] init];
        self.locationManager.delegate = self;
        // Check for iOS 8. Without this guard the code will crash with "unknown selector" on iOS 7.
        if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
            [self.locationManager requestWhenInUseAuthorization];
        }
        [self.locationManager startUpdatingLocation];


    // Location Manager Delegate Methods    
    - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
    {
        NSLog(@"%@", [locations lastObject]);

}

为了访问用户在iOS中的位置。您需要添加两个键

NSLocationWhenInUseUsageDescription

NSLocationAlwaysUsageDescription

进入信息。plist文件。

    <key>NSLocationWhenInUseUsageDescription</key>
    <string>Because I want to know where you are!</string>
    <key>NSLocationAlwaysUsageDescription</key>
    <string>Want to know where you are!</string>

请看下图。

对我来说，问题是CLLocationManagerDelegate类是私有的，这阻止了所有的委托方法被调用。我想这不是很常见的情况，但我想我应该提到它，以防它能帮助到任何人。

享受。

- (void)startLocationManager
{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone; //whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];
    [locationManager requestWhenInUseAuthorization]; // Add This Line


}

还有你的信息。plist文件
