iOS定位操作,获取当前位置

一、导入CoreLocation.framework

二、#import <CoreLocation/CoreLocation.h>

三、声明代理 <CLLocationManagerDelegate>

四、代码实现

1、声明

CLLocationManager *locationManager;//定义Manager  // 判断定位操作是否被允许  if([CLLocationManager locationServicesEnabled]) {      CLLocationManager *locationManager = [[[CLLocationManager alloc] init] autorelease];         self.locationManager.delegate = self;  }else {       //提示用户无法进行定位操作  }    // 开始定位  [locationManager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager       didUpdateToLocation:(CLLocation *)newLocation              fromLocation:(CLLocation *)oldLocation {     //latitude和lontitude均为NSString型变量          //纬度   self.latitude = [NSString  stringWithFormat:@"%.4f", newLocation.coordinate.latitude];            //经度   self.longitude = [NSString stringWithFormat:@"%.4f",          newLocation.coordinate.longitude];     }

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations  {      //此处locations存储了持续更新的位置坐标值，取最后一个值为最新位置，如果不想让其持续更新位置，则在此方法中获取到一个值之后让locationManager stopUpdatingLocation      CLLocation *currentLocation = [locations lastObject];            CLLocationCoordinate2D coor = currentLocation.coordinate;      self.latitude =  coor.latitude;      self.longitude = coor.longitude;           //[self.locationManager stopUpdatingLocation];        }

- (void)locationManager:(CLLocationManager *)manager         didFailWithError:(NSError *)error {       if (error.code == kCLErrorDenied) {        // 提示用户出错原因，可按住Option键点击 KCLErrorDenied的查看更多出错信息，可打印error.code值查找原因所在    }  }
