更改CLLocation的坐标

Question

我是Objective C的新手,所以这可能是一个微不足道的问题:

初始化位置后:

CLLocation *currentPoint = [[CLLocation alloc] initWithLatitude:0 longitude:0]:

我怎样才能改变纬度和经度呢？

Answer 1

以下是如何修改CLLocation的示例:

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{


    newLocation = [[[CLLocation alloc] initWithCoordinate:CLLocationCoordinate2DMake(newLocation.coordinate.latitude, -1.1874988592864875)
                                                 altitude:newLocation.altitude
                                       horizontalAccuracy:newLocation.horizontalAccuracy
                                         verticalAccuracy:newLocation.verticalAccuracy
                                            timestamp:newLocation.timestamp] autorelease];

这是另一个如何创建新CLLotation的示例:

CLLocation *newLocation = [[[CLLocation alloc] initWithCoordinate:CLLocationCoordinate2DMake(41.44994138650804, -1.1874988592864875)
                                                   altitude:0
                                         horizontalAccuracy:0
                                           verticalAccuracy:0
                                                  timestamp:[NSDate date]] autorelease];
