MapKit和CoreLocation

    实战应用

 1.首先导入两个包 MapKit.framework 和 CoreLocation.framework.

// 1. 实例化定位管理器

_locatiOnManager= [[CLLocationManager alloc] init];

// 2. 设置代理

_locationManager.delegate = self;

// 3. 定位精度

[_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];

// 4. 更新用户位置

[_locationManager startUpdatingLocation];

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

- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error
