集成iOS高德地图

一、前奏

这里只是个人集成过程中的遇到的点,现做下标记。

1,如果你需要集成涉及国外版地图,基于HTTPS的最新版本需要设置,需要注意基于国外定位,高德的不太精确(个人测试)

    [self.mapView performSelector:@selector(setShowsWorldMap:) withObject:@(YES)];

这个方法后台提供的国外地图是第三方的,是不稳定的,不推荐使用。集成国外版地图详情见:http://lbs.amap.com/dev/demo/switch-map#iOS

2,坐标转换

//将GPS转成高德坐标

CLLocationCoordinate2D amapcoord = MACoordinateConvert(CLLocationCoordinate2DMake(39.989612,116.480972),MACoordinateTypeGPS);

二、实战

1,创建地图

#import <MAMapKit/MAMapKit.h>

@property (nonatomic, strong)MAMapView *mapView; // 添加属性

// 添加到视图上
_mapView = [[MAMapView alloc] initWithFrame:self.view.bounds];

_mapView.delegate = self;

[self.view addSubview:_mapView];

2,设置中心点

CLLocationCoordinate2D centerPoint = CLLocationCoordinate2DMake(30.2740850000,120.1550700000);//纬度,经度

self.mapView.centerCoordinate = centerPoint; // 或者[self.mapView setCenterCoordinate:(centerPoint) animated:YES];

3,隐藏指南针

_mapView.showsCompass = NO;

4,隐藏比例尺

_mapView.showsScale = NO;

5,手势控制

_mapView.zoomEnabled = YES;    // NO表示禁用缩放手势,YES表示开启

_mapView.scrollEnabled = YES;  // NO表示禁用滑动手势,YES表示开启

6,设置地图语言(默认中文)

_mapView.language = MAMapLanguageEn;

7,添加标注(大头针)

MAPointAnnotation *pointAnnotation1 = [[MAPointAnnotation alloc] init];

pointAnnotation1.coordinate = CLLocationCoordinate2DMake(39.907465,116.337447);

pointAnnotation1.title = @"木樨地";

pointAnnotation1.subtitle = @"北京市西城区复兴门外大街29号楼三里河路";

[_mapView addAnnotation:pointAnnotation]; // 单个添加,多个添加[_mapView addAnnotations:@[pointAnnotation,pointAnnotation1,pointAnnotation2]];

8,自定义标注(大头针)

- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation

{

if ([annotation isKindOfClass:[MAPointAnnotation class]])

{

// 自定义标注图标

static NSString *reuseIndetifier = @"annotationReuseIndetifier";

MAAnnotationView *annotationView = (MAAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];

if (annotationView == nil)

{

annotationView = [[MAAnnotationView alloc] initWithAnnotation:annotation

reuseIdentifier:reuseIndetifier];

}

annotationView.image = [UIImage imageNamed:@"Point"]; // 换成你需要的标注图片

// 设置中心点偏移,使得标注底部中间点成为经纬度对应点

annotationView.centerOffset = CGPointMake(0, -9);

annotationView.canShowCallout = YES;    // 设置气泡可以弹出,默认为NO

annotationView.draggable = NO;        // 设置标注可以拖动,默认为NO

return annotationView;

/* 默认的标注图标

static NSString *pointReuseIndentifier = @"pointReuseIndentifier";

MAPinAnnotationView *annotationView = (MAPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

if (annotationView == nil)

{

annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndentifier];

}

annotationView.image = [UIImage imageNamed:@"Point"];

annotationView.canShowCallout = YES;  // 设置气泡可以弹出,默认为NO

annotationView.animatesDrop = YES;    // 设置标注动画显示,默认为NO

annotationView.draggable = YES;        // 设置标注可以拖动,默认为NO

annotationView.pinColor = MAPinAnnotationColorPurple;

return annotationView;

*/

}

return nil;

}

9,绘制折线

- (void)drawLine{

//构造折线数据对象

CLLocationCoordinate2D commonPolylineCoords[3];

commonPolylineCoords[0].latitude  = 39.957312;

commonPolylineCoords[0].longitude = 116.416261;

commonPolylineCoords[1].latitude  = 39.907465;

commonPolylineCoords[1].longitude = 116.337447;

commonPolylineCoords[2].latitude  = 39.991720;

commonPolylineCoords[2].longitude = 116.271057;

//构造折线对象

MAPolyline *commonPolyline = [MAPolyline polylineWithCoordinates:commonPolylineCoords count:3];

//在地图上添加折线对象

[_mapView addOverlay: commonPolyline];

}

// 设置折线的样式- (MAOverlayView *)mapView:(MAMapView *)mapView viewForOverlay:(id)overlay

{

if ([overlay isKindOfClass:[MAPolyline class]])

{

MAPolylineView *polylineView = [[MAPolylineView alloc] initWithPolyline:overlay];

polylineView.lineWidth = 5.f; // 折线的宽度

polylineView.strokeColor = [UIColor redColor]; // 折线的颜色

// 端点类型

polylineView.lineCap = kCGLineCapSquare;

// 连接类型

polylineView.lineJoin = kCGLineJoinBevel;

return polylineView;

}

return nil;

}

9.给标注点添加不同的图标

// 根据anntation生成对应的View- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation

{

if ([annotation isKindOfClass:[MAPointAnnotation class]])

{

// 自定义标注图标

static NSString *reuseIndetifier = @"annotationReuseIndetifier";

MAAnnotationView *annotationView = (MAAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];

if (annotationView == nil)

{

annotationView = [[MAAnnotationView alloc] initWithAnnotation:annotation

reuseIdentifier:reuseIndetifier];

}

annotationView.image = [UIImage imageNamed:@"Point"];

if ([annotation.title isEqualToString:@"海神庙"]) {

annotationView.image = [UIImage imageNamed:@"Point"];

}

if ([annotation.title isEqualToString:@"金巴兰海滩"]) {

annotationView.image = [UIImage imageNamed:@"pointNew"];

}

// 设置中心点偏移,使得标注底部中间点成为经纬度对应点

annotationView.centerOffset = CGPointMake(0, -9);

annotationView.canShowCallout = YES;    // 设置气泡可以弹出,默认为NO

annotationView.draggable = NO;        // 设置标注可以拖动,默认为NO

return annotationView;

/* 默认的标注图标

static NSString *pointReuseIndentifier = @"pointReuseIndentifier";

MAPinAnnotationView *annotationView = (MAPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

if (annotationView == nil)

{

annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndentifier];

}

annotationView.image = [UIImage imageNamed:@"Point"];

annotationView.canShowCallout = YES;  // 设置气泡可以弹出,默认为NO

annotationView.animatesDrop = YES;    // 设置标注动画显示,默认为NO

annotationView.draggable = YES;        // 设置标注可以拖动,默认为NO

annotationView.pinColor = MAPinAnnotationColorPurple;

return annotationView;

*/

}

return nil;

}

10.点击标注点,触发不同的事件

通过协议方法进行判断

- (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view

根据点击不同的标注点数据进行处理

MAPointAnnotation *pointAnnotation = (MAPointAnnotation *)mapView.selectedAnnotations[0];

NSLog(@"city =>%@,subtitle =>%@",pointAnnotation.title,pointAnnotation.subtitle);

例如:

- (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view{

NSLog(@"selectedAnnotations ==》%@",mapView.selectedAnnotations);

if (mapView.selectedAnnotations.count == 0) {

return;

}

MAPointAnnotation *pointAnnotation = (MAPointAnnotation *)mapView.selectedAnnotations[0];

NSLog(@"city =>%@,subtitle =>%@",pointAnnotation.title,pointAnnotation.subtitle);

for (int i = 0; i < self.addressArray.count; i++) {

AddressModel *model = (AddressModel *)self.addressArray[i];

if ([pointAnnotation.title isEqualToString:model.cityName]) {

// 给底部view赋值

if (self.bottomView.hidden) {

self.bottomView.hidden = NO;

}

self.bottomView.cityNameLable.text = model.cityName;

self.bottomView.cityEnglishLable.text = model.detail;

self.bottomView.avgpriceLable.text = [NSString stringWithFormat:@"人均:%d",i*100];

break;

}

}

}

11.在地图上显示所有标注点,通过协议

- (void)showAnnotations:(NSArray *)annotations animated:(BOOL)animated;

在视线内显示所有的标注,会自动计算最佳缩放比以将所有点显示出来

12.默认显示气泡

    [_mapView selectAnnotation:pointAnnotation animated:YES];

13.自定义标注点,例如更换图标

在 协议的回调函数mapView:viewForAnnotation:中修改 MAAnnotationView 对应的标注图片。示例代码如下:

- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id <MAAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MAPointAnnotation class]])
    {
        static NSString *pointReuseIndentifier = @"pointReuseIndentifier";
        MAPinAnnotationView  *annotationView = (MAPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

        if (annotationView == nil)
        {
            annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndentifier];
        }

        // 设置自定义图标
        annotationView.image = [UIImage imageNamed:@"price_lv5_yellow"];
       
        // 设置中心点偏移,使得标注底部中间点成为经纬度对应点
        annotationView.centerOffset = CGPointMake(0, -18);
       
//        如果要自定义标注点图标,一定要注释掉下面几行
//        annotationView.animatesDrop = YES;        //设置标注动画显示,默认为NO
//        annotationView.draggable = YES;           //设置标注可以拖动,默认为NO
//        annotationView.pinColor = MAPinAnnotationColorPurple;

        return annotationView;
    }

    return nil;
}

一定要注释掉下面几行,否则自定义的图标不会显示

//        annotationView.animatesDrop = YES;        //设置标注动画显示,默认为NO

//        annotationView.draggable = YES;           //设置标注可以拖动,默认为NO

//        annotationView.pinColor = MAPinAnnotationColorPurple;
