ios-oc-Gold map draws routes based on two coordinate points __ios

Since the start of the project to use the high-German map, but two items of the gold map of the map have been used, the basic process is the same.

1. Import the required SDK configuration ...

2.

Agent

<mamapviewdelegate, Amaplocationmanagerdelegate,amapsearchdelegate,amapnavidrivemanagerdelegate, Amapnavidriveviewdelegate>

Property

Map related

@property (Strong, nonatomic) Mamapview *mapview;

@property (Strong, nonatomic) Amaplocationmanager *locationmanager;

@property (Strong, nonatomic) mapointannotation *annotation; Map marking

@property (nonatomic, strong) Amaproute *route; Route planning

Navigation

@property (nonatomic, strong) Amapnavidrivemanager *drivemanager;

@property (nonatomic, strong) Amapnavipoint *startpoint;

@property (nonatomic, strong) Amapnavipoint *endpoint;

Set up agents

Self.drivemanager = [[Amapnavidrivemanager alloc] init];

[Self.drivemanager setdelegate:self];

Set starting point coordinates

Self.startpoint = [Amapnavipoint locationwithlatitude:startlat Longitude:startlon];

Self.endpoint = [Amapnavipoint locationwithlatitude:endlat Longitude:endlon];

Conduct route planning

[Self.drivemanager Calculatedriveroutewithstartpoints:@[self.startpoint]

Endpoints:@[self.endpoint]

Waypoints:nil

Drivingstrategy:amapnavidrivingstrategysingledefault];

#pragma mark-amapnavidrivemanager Delegate Route planning callback

-(void) Drivemanageroncalculateroutesuccess: (Amapnavidrivemanager *) Drivemanager

{

NSLog (@ "oncalculateroutesuccess");

Show path after successful calculation of road

[Self shownaviroutes];

}

Draw Route

-(void) shownaviroutes

{

if ([self.driveManager.naviRoutes Count] <= 0)

{

Return

}

[Self.mapview RemoveOverlays:self.mapView.overlays];

Show the path to the map

For (NSNumber *arouteid in [self.driveManager.naviRoutes AllKeys])

{

Amapnaviroute *aroute = [[Self.drivemanager naviroutes] Objectforkey:arouteid];

int count = (int) [[Aroute routecoordinates] count];

Add Path polyline

Cllocationcoordinate2d Coords[count];

for (int i = 0; i < count; i++)

{

Amapnavipoint *coordinate = [[Aroute routecoordinates] objectatindex:i];

Coords[i].latitude = [coordinate latitude];

Coords[i].longitude = [coordinate longitude];

}

Mapolyline *polyline = [Mapolyline polylinewithcoordinates:coords count:count];

[Self.mapview Addoverlay:polyline];

}

[Self.mapview showAnnotations:self.mapView.annotations Animated:no];

}

Set route color

-(Maoverlayrenderer *) Mapview: (Mamapview *) Mapview Rendererforoverlay: (ID <MAOverlay>) Overlay

{

if ([Overlay Iskindofclass:[mapolyline class]])

{

Mapolylinerenderer *polylinerenderer = [[Mapolylinerenderer alloc] initwithpolyline:overlay];

Polylinerenderer.strokecolor = [Uicolor Bluecolor];

Polylinerenderer.linewidth = 5.f;

return polylinerenderer;

}

return nil;

}
