iOS 第三方 map 地图

第一步 设置根控制器 添加导航栏信息 添加表格 设置代理 数据源

第二步 添加依赖库

第三步

@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>

{

NSArray *_provinceArr;

}

@end

@implementation ViewController

• (void)viewDidLoad {

  [super viewDidLoad];

  //初始化

  _provinceArr = @[@“石家庄”,@“北京”,@“太原”,@“济南”,@“西安”];

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return _provinceArr.count;

}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];

if (!cell) {

    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];

}

cell.textLabel.text = _provinceArr[indexPath.row];

return cell;

}

第四步

创建跳转控制器 里面设置属性

@property (nonatomic , copy)NSString *passProvince;//传递生辉的字符串

第五步 属性传值 跳转

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

//得到选中行对应的文本

NSString *pro = _provinceArr[indexPath.row];

//实例化地图控制器

mapViewController *mapa = [[mapViewController alloc]init];

mapa.passProvince = pro;

[self.navigationController pushViewController:mapa animated:YES];

}

第六步

#import <MapKit/MapKit.h>

#import <CoreLocation/CoreLocation.h>

@interface mapViewController ()<CLLocationManagerDelegate,MKMapViewDelegate>

@property (nonatomic , strong)MKMapView *mapView;

//地理位置管理者

@property (nonatomic ,strong)CLLocationManager *locManger;

@end

@implementation mapViewController

• (void)viewDidLoad {

  [super viewDidLoad];

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

  //卫星+平面的混合模式

  self.mapView.mapType = MKMapTypeHybrid;

  self.mapView.mapType = MKMapTypeStandard;

  [self.view addSubview:self.mapView];

  self.mapView.delegate = self;

  //获取当前位置按钮的创建

  UIButton *currentBtn = [UIButton buttonWithType:UIButtonTypeCustom];

  currentBtn.frame = CGRectMake(10, self.view.frame.size.height - 80, 40, 40);

  [currentBtn setTitle:@“定位” forState:UIControlStateNormal];

  currentBtn.backgroundColor = [UIColor blueColor];

  [currentBtn addTarget:self action:@selector(currentBtnDidPress:) forControlEvents:UIControlEventTouchUpInside];

  [self.view addSubview:currentBtn];

  //实例化位置管理利器对象

  self.locManger = [[CLLocationManager alloc]init];

  self.locManger.delegate = self; //设置代理

  //申请用户授权

  [self.locManger requestAlwaysAuthorization];

}

-(void)currentBtnDidPress:(id)sender{

//开始获取位置信息 调用此方法后 协议中的方法才会执

[self.locManger startUpdatingLocation];

}

//获取到位置信息后触发的回调方法

• (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{

  //获取当前位置

  CLLocation *curLoc = [locations lastObject];

  //获取经纬度

  CLLocationCoordinate2D curCoor = curLoc.coordinate;

  NSLog(@“经度:%g,纬度:%g”,curCoor.longitude,curCoor.latitude);

  //地图显示区域缩小

  MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(curCoor, 800, 800);

  [self.mapView setRegion:region animated:YES];

  //地址解析

  CLGeocoder *geocoder = [[CLGeocoder alloc]init];

  [geocoder reverseGeocodeLocation:curLoc completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {

    //获取其中一个地址信息
  
    CLPlacemark *plack = [placemarks lastObject];
  
    //做一个大头针 定在当前位置上 锚点
  
    MKPointAnnotation *point = [[MKPointAnnotation alloc]init];
  
    point.title = plack.name;
  
    point.coordinate = curCoor;
  
    [self.mapView addAnnotation:point];
  

  }];

}

//用于设置锚点视图的回调方法

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation{

static NSString *str = @"pin";

MKPinAnnotationView *pin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:str];

//掉落效果

pin.animatesDrop = YES;

//泡泡效果

pin.canShowCallout = YES;

return pin;

}

设置 info.plist 里面 添加
