原生地图

第一步 导入框架

#import <MapKit/MapKit.h>

第二步，如果用到定制大头针落下动画，和复用方法则需要代理
@interface RootViewController ()<MKMapViewDelegate>

第三步正文

- (void)viewDidLoad {

    [super viewDidLoad];

    _mapView = [[MKMapView alloc]initWithFrame:self.view.frame];

    [self.view addSubview:_mapView];

    //设置具体显示位置(显示坐标用到CLLocationCoordinate2D)

    CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(39.896304, 116.410103);

    //设置放大比例 (数字越小放大比例越大,记住最后一个就行了)

    MKCoordinateSpan span = MKCoordinateSpanMake(0.1, 0.1);

    MKCoordinateRegion region = MKCoordinateRegionMake(coord, span);

    [_mapView setRegion:region];

    _mapView.delegate = self;

    //添加长按手势

    UILongPressGestureRecognizer * longPress = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longPressClick:)];

    [_mapView addGestureRecognizer:longPress];

    

}

-(void)longPressClick:(UILongPressGestureRecognizer *)longPress

    /*

     此状态长按会出现无数个大头针

    //添加大头针

    MKPointAnnotation * annotation = [[MKPointAnnotation alloc]init];

    annotation.title = @"主标题";

    annotation.subtitle = @"副标题";

    //设置位置

    //获取中心点

    CGPoint point = [longPress locationInView:_mapView];

    //折算经纬度

    CLLocationCoordinate2D coord = [_mapView convertPoint:point toCoordinateFromView:_mapView];

    annotation.coordinate = coord;

    [_mapView addAnnotation:annotation];

     //修改后的代码
