}
- (void)createGPSMap{
// 初始化位置服务
self.locationManage = [[CLLocationManager alloc]init];
// 要求CLLocationManager对象返回全部信息
_locationManage.distanceFilter = kCLDistanceFilterNone;
// 设置定位精度
_locationManage.desiredAccuracy = kCLLocationAccuracyBest;
// 设置代理
_locationManage.delegate = self;
定位获取位置及位置编码-反编码
我们的应用程序,可以通过添加Core Location框架所包含的类,获取设备的地图位置。
添加CoreLocation.framework框架,导入#import<CoreLocation/CoreLocation.h>。
使用地图服务时,会消耗更多地设备电量.因此,在获取到设备的位置后,应该停止定位来节省电量。
我们通过一个demo来展示内容与效果
