ios - 在 iOS 上获取当前位置

Question

我需要获取当前用户位置(纬度、经度)，但我找不到解决方案，因为所有解决方案都只适用于 iOS 6、7、8。例如，我有这段代码，但在 iOS 11.3.1 上它仍然无法正常工作。

#import <CoreLocation/CoreLocation.h>

@interface ViewController () <CLLocationManagerDelegate>

@property (weak, nonatomic) IBOutlet UILabel *latitudeValue;
@property (weak, nonatomic) IBOutlet UILabel *longtitudeValue;

@property (nonatomic,strong) CLLocationManager *locationManager;

- (void)viewDidLoad
{
    [super viewDidLoad];

    if ([CLLocationManager locationServicesEnabled]) {
        self.locationManager = [[CLLocationManager alloc] init];
        self.locationManager.delegate = self;
        [self.locationManager startUpdatingLocation];
    } else {
        NSLog(@"Location services are not enabled");
    }
}

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations lastObject];
    self.latitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.latitude];
    self.longtitudeValue.text = [NSString stringWithFormat:@"%f", location.coordinate.longitude];
}

从 iOS 10 开始，您需要将两个键添加到 info.plist 中

NSLocationAlwaysUsageDescription key to your Info.plist file. (Xcode displays this key as "Privacy - Location Always Usage Description" in the Info.plist editor.)

对于 iOS 11

Add the NSLocationWhenInUseUsageDescription key and the NSLocationAlwaysAndWhenInUseUsageDescription key to your Info.plist file. (Xcode displays these keys as "Privacy - Location When In Use Usage Description" and "Privacy - Location Always and When In Use Usage Description" in the Info.plist editor.)
