ios地图和定位学习四《获取当前位置的location》

通过CLLocationManager类可以获取到当前位置的经纬度：

1.要包含头文件<CoreLocation/CoreLocation.h>

2.添加CLLocationManagerDelegate协议

3.在下面这个函数中：

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

newLocation.coordinate.latitude     当前位置的经度

newLocation.coordinate.longitude   当前位置的纬度

 

在.h文件中：

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


@interface mapViewController : UIViewController<CLLocationManagerDelegate>

@property (nonatomic, strong) CLLocationManager* myLocationManager;

@end

在.m文件中：

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

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    if ([CLLocationManager locationServicesEnabled]) {
        self.myLocationManager = [[CLLocationManager alloc] init];
        self.myLocationManager.delegate = self;
        [self.myLocationManager startUpdatingLocation];
    }
}
