CLLocationCoordinate2D到CLLocation
CLLocationCoordinate2D到CLLocation
提问于 2010-02-23 21:49:16
我的viewDidLoad中有以下循环：
for(int i=1; i<[eventsArray count]; i++) {
NSArray *componentsArray = [[eventsArray objectAtIndex:i] componentsSeparatedByString:@","];
if([componentsArray count] >=6) {
Koordinate *coord = [[Koordinate alloc] init];
coord.latitude = [[componentsArray objectAtIndex:0] floatValue];
coord.longtitude = [[componentsArray objectAtIndex:1] floatValue];
coord.magnitude = [[componentsArray objectAtIndex:2] floatValue];
coord.depth = [[componentsArray objectAtIndex:3] floatValue];
coord.title = [componentsArray objectAtIndex:4];
coord.strasse = [componentsArray objectAtIndex:5];
coord.herkunft = [componentsArray objectAtIndex:6];
coord.telefon = [componentsArray objectAtIndex:7];
coord.internet = [componentsArray objectAtIndex:8];
[eventPoints addObject:coord];
}coord为CLLocationCoordinate2D
但是我如何在下面的方法中使用coord，因为我需要这个来获得两个coord之间的距离：
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation{
}请帮帮我，我被困住了！
感谢你们事前的帮助

CLLocation有一个名为-(id)initWithLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude的初始化方法。然后使用- (CLLocationDistance)getDistanceFrom:(const CLLocation *)location获取两个CLLocation对象之间的距离。

对于斯威夫特的观众，
我有一个名为"fetchCafesArroundLocation“的方法，它会在地图移动后刷新。这就是我如何将经度和经度从CLLocationCoordiate2d导入CLLocation，然后将CLLocation变量传递给处理方法。
func mapView(mapView: MKMapView!, regionDidChangeAnimated animated: Bool){
var centre = mapView.centerCoordinate as CLLocationCoordinate2D
var getLat: CLLocationDegrees = centre.latitude
var getLon: CLLocationDegrees = centre.longitude
var getMovedMapCenter: CLLocation = CLLocation(latitude: getLat, longitude: getLon)
self.lastLocation = getMovedMapCenter
self.fetchCafesAroundLocation(getMovedMapCenter)
