IPhone定位当前位置
1、需要加入CoreLocation.framework,导入#import <CoreLocation/CoreLocation.h>
2、在类中生命两个变量,并实现代理
@interface ViewController () <CLLocationManagerDelegate>{ CLLocationManager * locationManager; CLLocationCoordinate2D curLocation; }
3、定位的方法如下
//获得自己的地理位置信息 - (void) getCurrentLocation { //开始探测位置 if (locationManager == nil) { locationManager = [[CLLocationManager alloc] init]; } if ([CLLocationManager locationServicesEnabled]) { locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = 10.0f; /* 启动对当前位置的搜索,只要当前位置移动的范围超过了distanceFilter指定的范围, 那么就会重新收到最新的坐标位置信息,如果要关闭对位置的更新,需要调用 stopUpdatingLocation */ [locationManager startUpdatingLocation]; } }
4、在代理方法中获得地理位置
//响应当前位置的更新,在这里记录最新的当前位置 - (void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ NSLog(@"newLocation:%@",[newLocation description]); curLocation = newLocation.coordinate; }
