iOS百度地图问题总结(三)

- (void)viewDidLoad { 
[super viewDidLoad]; 
_locService = [[BMKLocationService alloc] init]; _locService.delegate = self; 
_mapView = [[BMKMapView alloc] initWithFrame:[UIScreen mainScreen].bounds];
 if ([[UIDevice currentDevice].systemVersion doubleValue] >= 8.0) { 
// 主动请求权限
 self.mgr = [[CLLocationManager alloc] init]; 
self.mgr.delegate = self;
 [self.mgr requestAlwaysAuthorization];
 } 
[self.view addSubview:_mapView];
 [_locService startUserLocationService]; _mapView.userTrackingMode = BMKUserTrackingModeFollow;//设置定位的状态 
_mapView.showsUserLocation = YES;//显示定位图层
}
/** 
*用户位置更新后，会调用此函数 
*@param userLocation 新的用户位置 
*/
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation{
 [_mapView updateLocationData:userLocation]; 
if (userLocation != nil) { 
NSLog(@"%f %f", userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude); 
}
}
