1.创建导航 在导航上创建定位按钮
2.引入两个依赖库 一个是地图的 一个是定位的
在VC.m里面：
引入两个框架 地图和定位的框架
#import “ViewController.h”
//引入头文件 ‘地图框架’
#import <MapKit/MapKit.h>
//引入头文件 ‘定位框架’
#import <CoreLocation/CoreLocation.h>
@interface ViewController ()<MKMapViewDelegate , CLLocationManagerDelegate>
//定义属性 ‘地图视图’
@property(nonatomic,strong)MKMapView *MapView;
//定义属性 ‘地理位置管理者’
@property(nonatomic,strong)CLLocationManager *locManager;
@end
@implementation ViewController
-
(void)viewDidLoad {
[super viewDidLoad];self.title = @“地图”;
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@“附近违章高发地” style:UIBarButtonItemStyleDone target:self action:@selector(click)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@“定位” style:UIBarButtonItemStyleDone target:self action:@selector(currentBtnDidPress:)];//初始化MKMapView ‘地图视图’
self.MapView = [[MKMapView alloc]initWithframe:self.view.frame];
//设置地图的样式 ‘MKMapTypeSatellite卫星地图’ ‘MKMapTypeStandard平面地图’
self.MapView.mapType = MKMapTypeStandard;
//签订协议
self.MapView.delegate = self;
//添加到视图
[self.view addSubview:self.MapView];//实例化位置管理者对象
self.locManager = [[CLLocationManager alloc]init];
//签订协议
self.locManager.delegate = self;
//申请用户授权
[self.locManager requestWhenInUseAuthorization];
}
-(void)click{
// NextViewController *next = [[NextViewController alloc]init];
// [self.navigationController pushViewController:next animated:YES];
}
//获取当前按钮触发
-(void)currentBtnDidPress:(id)sender{
}
//获取当前位置信息后触发的回调方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
}
//设置锚点视图的回调方法，当地图调用addAnnotation：方法时会触发 点击大头针是触发的方法
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation{
//静态字符串标识
static NSString *iden = @“pin”;
//初始化描点视图
MKPinAnnotationView *pin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:iden];
}
