    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;
