iOS:获取位置之间的距离

Question

请不要在未阅读整个问题的情况下将其标记为重复

在 iOS 中不显示 map 的情况下，有没有办法获取两个 CLLocation 点之间的自驾路线的长度？

绝非乌鸦飞过!!!但是就像在MK驾驶模式下

我不能使用谷歌，因为我必须在谷歌地图上显示结果。

我找到了这段代码，但这只在显示 iOS map 时有效:

-(void)showMapRouteFromCurrentLocation
{
    CLLocationCoordinate2D currentUserCoordinate = YourCoordinate;
    //currentUserCoordinate.latitude=  +53.509980;
    //currentUserCoordinate.longitude =  -0.133700;

    MKPlacemark *place = [[MKPlacemark alloc]
                          initWithCoordinate:currentUserCoordinate
                          addressDictionary:nil];


    MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:place];

    NSDictionary *routeOption = [[NSDictionary alloc] initWithObjectsAndKeys:MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsDirectionsModeKey, nil];

    [mapItem openInMapsWithLaunchOptions:routeOption];
}

但这不是我需要的。

正如 brainray 所说，从 iOS7 开始，您可以执行以下操作:

MKDirectionsRequest *routeRequest = [[MKDirectionsRequest alloc] init];
routeRequest.transportType = MKDirectionsTransportTypeAutomobile;
[routeRequest setSource:startPoint]; // startPoint is an MKMapItem with the starting lat/long coordinate
[routeRequest setDestination :endPoint]; // endPoint an MKMapItem with the ending lat/long coordinate

MKDirections *routeDirections = [[MKDirections alloc] initWithRequest:routeRequest];
[routeDirections calculateDirectionsWithCompletionHandler:^(MKDirectionsResponse * routeResponse, NSError *routeError)
{
    // Check for error and then do something with the route...
    MKRoute *route = routeResponse.routes[0];
}];
