高德地图初步使用-多点路线连接

demo中存在错误：- (void)initRoute里面的 NSUInteger count = 14;就可以了。非常感谢读者的提醒。

<key>NSAppTransportSecurity</key><dict>    <key>NSAllowsArbitraryLoads</key>    <true/></dict>

<key>LSApplicationQueriesSchemes</key><array>    <string>iosamap</string></array>

1.这两个加到Info.plist 里

2.pod导入地图包

pod 'AMap3DMap' #3D地图SDKpod 'AMapSearch' #搜索服务SDK

3.引头文件

#import <MAMapKit/MAMapKit.h>

4.签代理

<MAMapViewDelegate>

5.注册key

[MAMapServicessharedServices].apiKey =@"9efec5aeb9aa647cad07cd938a2587b8";

6.描绘路线

- (void)initRoute{        NSUInteger count = 11;    CLLocationCoordinate2D * coords = malloc(count * sizeof(CLLocationCoordinate2D));        coords[0] = CLLocationCoordinate2DMake(39.93563,  116.387358);    coords[1] = CLLocationCoordinate2DMake(39.935564,   116.386414);    coords[2] = CLLocationCoordinate2DMake(39.935646,  116.386038);    coords[3] = CLLocationCoordinate2DMake(39.93586, 116.385791);    coords[4] = CLLocationCoordinate2DMake(39.93586, 116.385791);    coords[5] = CLLocationCoordinate2DMake(39.937983, 116.38474);    coords[6] = CLLocationCoordinate2DMake(39.938616, 116.3846);    coords[7] = CLLocationCoordinate2DMake(39.938888, 116.386971);    coords[8] = CLLocationCoordinate2DMake(39.938855, 116.387047);    coords[9] = CLLocationCoordinate2DMake(39.938172,  116.387132);    coords[10] = CLLocationCoordinate2DMake(39.937604, 116.387218);    coords[11] = CLLocationCoordinate2DMake(39.937489, 116.387132);    coords[12] = CLLocationCoordinate2DMake(39.93614,  116.387283);    coords[13] = CLLocationCoordinate2DMake(39.935622,  116.387347);        [self showRouteForCoords:coords count:count];        if (coords) {        free(coords);    }    }

7.显示标记点

- (void)showRouteForCoords:(CLLocationCoordinate2D *)coords count:(NSUInteger)count{    //show route    MAPolyline *route = [MAPolyline polylineWithCoordinates:coords count:count];    [self.map addOverlay:route];        NSMutableArray * routeAnno = [NSMutableArray array];    for (int i = 0 ; i < count; i++)    {        MAPointAnnotation * a = [[MAPointAnnotation alloc] init];        a.coordinate = coords[i];        a.title = @"route";        [routeAnno addObject:a];    }    [self.map addAnnotations:routeAnno];    [self.map showAnnotations:routeAnno animated:NO];    }

8.显示标记点间的直线

-(MAOverlayView *)mapView:(MAMapView *)mapView viewForOverlay:(id<MAOverlay>)overlay{    if ([overlay isKindOfClass:[MAPolyline class]])    {        MAPolylineView *polylineView = [[MAPolylineView alloc] initWithPolyline:overlay];                polylineView.lineWidth   = 3.f;        polylineView.strokeColor = [UIColor colorWithRed:0 green:0.47 blue:1.0 alpha:0.9];                return polylineView;    }        return nil;}

9.创建地图

- (MAMapView *)map{    if (!_map)    {        _map = [[MAMapView alloc] initWithFrame:self.view.frame];        [_map setDelegate:self];                //加入annotation旋转动画后，暂未考虑地图旋转的情况。        _map.rotateCameraEnabled = NO;        _map.rotateEnabled = NO;    }    return _map;}

最后:就可以看见画出的线路了

//显示地图

    [self.viewaddSubview:self.map];

//显示路径

    [selfinitRoute];
