iOS App地图功能开发（4）MapKit地图用showsUs

1.加入头文件
#import <CoreLocation/CoreLocation.h>
2.添加代理
CLLocationManagerDelegate
3.创建对象
@property (strong,nonatomic) CLLocationManager *cllocationManager;

- (CLLocationManager *)cllocationManager {
    if (!_cllocationManager) {
        _cllocationManager = [[CLLocationManager alloc] init];
        _cllocationManager.delegate = self;
        _cllocationManager.distanceFilter = kCLLocationAccuracyNearestTenMeters;
        _cllocationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
        if ([CLLocationManager locationServicesEnabled]) {
            [_cllocationManager requestWhenInUseAuthorization];
            
        } else {
            
        }
    }
    return _cllocationManager;
}

4.在viewDidLoad添加开始定位语句：
[self.cllocationManager startUpdatingLocation];

5.在代理方法中，得到定位数据
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations {
    CLLocation * currentLocation = [locations lastObject];
    NSLog(@"%f %f",currentLocation.coordinate.latitude,currentLocation.coordinate.longitude);
   
}

6.在info.Plist添加定位权限
