RedBlueThing 的答案对我来说效果很好。这是我如何做到的一些示例代码。

标题

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface yourController : UIViewController <CLLocationManagerDelegate> {
    CLLocationManager *locationManager;
}

@end

主文件

在初始化方法中

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];

回调函数

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
    NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
}

iOS 6

在 iOS 6 中，委托功能已被弃用。新代表是

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

因此要获得新的职位使用

[locations lastObject]

iOS 8

在 iOS 8 中，应在开始更新位置之前明确询问权限

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    [self.locationManager requestWhenInUseAuthorization];

[locationManager startUpdatingLocation];

您还必须为应用程序的 Info.plist
中的NSLocationAlwaysUsageDescriptionorNSLocationWhenInUseUsageDescription键添加一个字符串。否则调用startUpdatingLocation将被忽略，您的委托将不会收到任何回调。

最后，当您完成阅读位置时，请在合适的位置调用 stopUpdating 位置。

[locationManager stopUpdatingLocation];
