iPhone开发之地图定位（CoreLocation和Mapkit框架）简易编程
下面介绍的时地图定位和位置反编码

// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
CLLocationManager *locationManager = [[CLLocationManager alloc] init];
//设置过滤信息
// [locationManager setDistanceFilter:<#(CLLocationDistance)#>]
//设置定位的精度
[locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
locationManager.delegate = self;
//开始实时定位
[locationManager startUpdatingLocation];
return YES;
}
//实时定位调用的方法, 6.0过期的方法
#pragma mark - CLLocationManager delegate
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation {
CLLocationCoordinate2D coordinate = newLocation.coordinate;
NSLog(@"经度：%f,纬度：%f",coordinate.longitude,coordinate.latitude);
//停止实时定位
[manager stopUpdatingLocation];
//计算两个位置的距离
// float distance = [newLocation distanceFromLocation:oldLocation];

//------------------位置反编码---5.0之后使用-----------------
