Map1

1.导入地图的库:Mapkit.framework

2.在导入到工程.m中 导入对应的系统文件 如:

<MapKit/MapKit.h>

MKMapView *mapView = [[MKMapView
alloc]initWithFrame:self.view.bounds];
mapView.delegate = self;
//地图样式
mapView.mapType = MKMapTypeHybrid;
// //缩放
// mapView.zoomEnabled = NO;
// //滑动
// mapView.scrollEnabled = NO;
//显示当前位置，位置发生变化时候会显示当前位置
mapView.showsUserLocation =
YES;
[self.view
addSubview:mapView];

//标注 (大头针)


自定义类
//添加的标注得自定义，同时实现<#(id<MKAnnotation>)#>协议
MyAnnotation *ann = [[MyAnnotation
alloc]init];
ann.coordinate =
CLLocationCoordinate2DMake(37.192279, -122.015586);
ann.title= @"精英";
ann.subtitle = @"河北四期";

[mapView addAnnotation:ann];

//覆盖物
这里要能显示效果需要调用渲染器-----在MKMapViewDelegate 的代理方法理写

CLLocationCoordinate2D points[4];//个数
points[0] =
CLLocationCoordinate2DMake(37.192279, -122.015586);
points[1] =
CLLocationCoordinate2DMake(30.192279, -122.015586);
points[2] =
CLLocationCoordinate2DMake(30.192279, -112.015586);
points[3] =
CLLocationCoordinate2DMake(37.192279, -112.015586);
// 闭合曲线

// MKPolygon *gon = [MKPolygon polygonWithCoordinates:points count:4];
// [mapView addOverlay:gon];

//折线
MKPolyline *line = [MKPolyline
polylineWithCoordinates:points count:4];
[mapView addOverlay:line];

//圈圈
MKCircle *circle = [MKCircle
circleWithCenterCoordinate:points[3]
radius:100000];
[mapView addOverlay:circle];

//
}


//给覆盖物渲染颜色 ------------------代理方法
- (MKOverlayRenderer *)mapView:(MKMapView *)mapView rendererForOverlay:(id <MKOverlay>)overlay {

//判断是哪个类

if ([overlay isKindOfClass:[MKPolygon
class]]) {
MKPolygonRenderer *render = [[MKPolygonRenderer
alloc]initWithPolygon:overlay];
// 画笔颜色
render.strokeColor = [UIColor
redColor];
//填充色

render.fillColor = [UIColor
greenColor];
//线的宽度
render.lineWidth =
3;

return render;

}else if ([overlay
isKindOfClass:[MKPolyline
class]]){

MKPolylineRenderer *render = [[MKPolylineRenderer
alloc]initWithPolyline:overlay];
render.strokeColor = [UIColor
purpleColor];
render.lineWidth =
1;
return render;

}else{
MKCircleRenderer *render = [[MKCircleRenderer
alloc]initWithOverlay:overlay];
render.strokeColor = [UIColor
magentaColor];
render.fillColor = [UIColor
cyanColor];
render.lineWidth =
2;
return render;
}

return nil;
}
