类似美团的iOS地图定位及调用苹果系统导航

引入头文件

#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
#import "MapViewController.h"
#import "AnnotationModel.h"

属性

@interface MapViewController ()<CLLocationManagerDelegate,MKMapViewDelegate>
@property (nonatomic, strong) CLLocationManager *manager;
@property (nonatomic, strong) MKMapView *mapView;
@property (nonatomic, strong) CLGeocoder *myGeocoder;
@property (nonatomic, strong) MKAnnotationView *annotation;
// 用于显示目的地详情，及导航按钮
@property (nonatomic, strong) UIView *viewLabel;
// 导航按钮
@property (nonatomic, strong) UIButton *guidanceBtn;
@property (nonatomic ,assign) CLLocationCoordinate2D ToCoords;
@property (nonatomic ,assign) CLLocationCoordinate2D FromCoords;

初始化

_manager = [[CLLocationManager alloc]init];
_manager.delegate = self;
[_manager requestAlwaysAuthorization];
[_manager startUpdatingLocation];

_mapView = [[MKMapView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREENHEIGHT)];
_mapView.delegate = self;
_mapView.showsUserLocation = YES;
_mapView.userTrackingMode = MKUserTrackingModeFollow;

_viewLabel = [[UIView alloc] initWithFrame:CGRectMake(0, SCREEN_HEIGHT - 80-64, SCREEN_WIDTH, 80)];
_viewLabel.backgroundColor = [UIColor whiteColor];
[_mapView addSubview:_viewLabel];

_guidanceBtn = [[UIButton alloc]initWithFrame:CGRectMake(SCREEN_WIDTH - 52, 5, 50, 30)];
_guidanceBtn.backgroundColor = [UIColor orangeColor];
[_guidanceBtn setTitle:@"导航" forState:UIControlStateNormal];
[_viewLabel addSubview:_guidanceBtn];
[_guidanceBtn addTarget:self action:@selector(btnClick) forControlEvents:UIControlEventTouchUpInside];


[self.view addSubview:self.mapView];
_mapView.delegate = self;

设置定位精确度

_manager.desiredAccuracy = kCLLocationAccuracyBest;

地理编码获取目的地经纬度

  _myGeocoder = [[CLGeocoder alloc]init];

  [self.myGeocoder geocodeAddressString:@"光谷国际广场"
                       completionHandler:^(NSArray *placemarks,NSError *error){
        if(nil == error && [placemarks count] > 0){
        CLPlacemark *pm = [placemarks objectAtIndex:0];

        CLLocationCoordinate2D coords=
                         CLLocationCoordinate2DMake(pm.location.coordinate.latitude,            pm.location.coordinate.longitude);
        self.ToCoords = coords;


        // 自定义的大头针
        AnnotationModel *anno = [[AnnotationModel alloc]init];
        anno.iconName = @"category_2";

        anno.coordinate = CLLocationCoordinate2DMake(pm.location.coordinate.latitude, pm.location.coordinate.longitude);

        NSLog(@"%f,%f",anno.coordinate.latitude,anno.coordinate.longitude);




        // 地图显示精度            
        float zoomLevel = 0.01;
        MKCoordinateRegion region = MKCoordinateRegionMake(coords, MKCoordinateSpanMake(zoomLevel, zoomLevel));
        [_mapView setRegion:region animated:YES];
            [_mapView addAnnotation:anno];





    }else if([placemarks count] == 0 && error == nil){
        NSLog(@"找不到给定地址的经纬度");
    }
}];

#pragma mark - CLLocationManager的代理方法

/** 用户拒绝或同意授权后调用*/
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{

}


- (void)locationManager:(CLLocationManager *)manager
 didUpdateLocations:(NSArray<CLLocation *> *)locations
{
    NSLog(@"--%f",manager.location.coordinate.latitude);
    NSLog(@"--%f",manager.location.coordinate.longitude);
    self.FromCoords = manager.location.coordinate;
    [self.manager stopUpdatingLocation];

}

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:   (id<MKAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MKUserLocation class]])
         return nil;

    _annotation = [self.mapView dequeueReusableAnnotationViewWithIdentifier:@"ID"];

     if (_annotation == nil) {
         _annotation = [[MKAnnotationView alloc]initWithAnnotation:annotation       reuseIdentifier:@"ID"];
      }
   _annotation.canShowCallout = YES;

 // 根据模型对象，决定本大头针显示的图片样式。
  NSString *iconName = ((AnnotationModel *)annotation).iconName;
  _annotation.image = [UIImage imageNamed:iconName];



return _annotation;

}

调用苹果自带地图导航

- (void)btnClick
{

 //当前的位置
 MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
 //起点
 //MKMapItem *currentLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:coords1 addressDictionary:nil]];
 //目的地的位置
 MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:self.ToCoords addressDictionary:nil]];

 toLocation.name = @"目的地";



 NSArray *items = [NSArray arrayWithObjects:currentLocation, toLocation, nil];
 NSDictionary *options = @{ MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving, MKLaunchOptionsMapTypeKey: [NSNumber numberWithInteger:MKMapTypeStandard], MKLaunchOptionsShowsTrafficKey:@YES };
 //打开苹果自身地图应用，并呈现特定的item
 [MKMapItem openMapsWithItems:items launchOptions:options];

}

AnnotationModel.h

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>

@interface AnnotationModel : NSObject <MKAnnotation>

@property (nonatomic, copy) NSString *iconName;
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;
@property(nonatomic, readonly, copy) NSString *title;
@property(nonatomic, readonly, copy) NSString *subtitle;

@end

AnnotationModel.m

#import "AnnotationModel.h"

@implementation AnnotationModel

@end
