cocoa-touch - 更改 CLLocation 的坐标

Question

我是 Objective C 新手，所以这可能是一个小问题:

初始化位置后:

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

以后如何更改纬度和经度？

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];

这是如何创建新 CLLotation 的另一个示例:

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