MapKit

一、mapkit的基本使用

#import "ViewController.h"
#import 
#import 
@interface ViewController ()
@property (weak, nonatomic) IBOutlet MKMapView *mapView;


/**   */
@property (nonatomic, strong) CLLocationManager *lM;

@end

@implementation ViewController


- (CLLocationManager *)lM
{
    if (!_lM) {
        _lM = [[CLLocationManager alloc] init];
        if ([_lM respondsToSelector:@selector(requestAlwaysAuthorization)])
        {
            [_lM requestAlwaysAuthorization];
        }
    }
    return _lM;
}

- (void)viewDidLoad {
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    /**
     MKMapTypeStandard = 0,
     MKMapTypeSatellite,
     MKMapTypeHybrid,
     MKMapTypeSatelliteFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
     MKMapTypeHybridFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
     */
//    self.mapView.mapType = MKMapTypeSatelliteFlyover;
    
    
//    self.mapView.zoomEnabled = NO;
//    
////    self.mapView.showsCompass = NO;
//    self.mapView.showsScale = YES;
    
    [self lM];
//    self.mapView.showsUserLocation = YES;
    
    self.mapView.userTrackingMode = MKUserTrackingModeFollowWithHeading;
    
    
}

@end

二、mapkit的中级使用

#import "ViewController.h"
#import 
#import 
@interface ViewController ()
@property (weak, nonatomic) IBOutlet MKMapView *mapView;


/**   */
@property (nonatomic, strong) CLLocationManager *lM;

@end

@implementation ViewController


- (CLLocationManager *)lM
{
    if (!_lM) {
        _lM = [[CLLocationManager alloc] init];
        if ([_lM respondsToSelector:@selector(requestAlwaysAuthorization)])
        {
            [_lM requestAlwaysAuthorization];
        }
    }
    return _lM;
}

- (void)viewDidLoad {
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    /**
     MKMapTypeStandard = 0,
     MKMapTypeSatellite,
     MKMapTypeHybrid,
     MKMapTypeSatelliteFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
     MKMapTypeHybridFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
     */
//    self.mapView.mapType = MKMapTypeSatelliteFlyover;
    
    
//    self.mapView.zoomEnabled = NO;
//    
////    self.mapView.showsCompass = NO;
//    self.mapView.showsScale = YES;
    
    [self lM];
   self.mapView.delegate = self;
    self.mapView.showsUserLocation = YES;
    
//    self.mapView.userTrackingMode = MKUserTrackingModeFollowWithHeading;
    
}

#pragma mark - MKMapViewDelegate
/**
 *  更新到位置
 *
 *  @param mapView      地图
 *  @param userLocation 位置对象
 */
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    /**
     *  MKUserLocation (大头针模型)
     *
     
     *
     */
    userLocation.title = @"银江软件园";
    userLocation.subtitle = @"城市宝";
    
    
    // 设置地图显示中心
//    [self.mapView setCenterCoordinate:userLocation.location.coordinate animated:YES];
    
    
    // 设置地图显示区域
    MKCoordinateSpan span = MKCoordinateSpanMake(0.051109, 0.034153);
    MKCoordinateRegion region = MKCoordinateRegionMake(userLocation.location.coordinate, span);
    [self.mapView setRegion:region animated:YES];
    
    
    
}

三、大头针的添加

#import "ViewController.h"
#import 
#import 
#import "XMGAnno.h"

@interface ViewController ()

@property (weak, nonatomic) IBOutlet MKMapView *mapView;

/** <#注释#> */
@property (nonatomic, strong) CLGeocoder *geoC;

@end

@implementation ViewController

- (CLGeocoder *)geoC
{
    if (!_geoC) {
        _geoC = [[CLGeocoder alloc] init];
    }
    return _geoC;
}




-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    
    // 1. 获取当前触摸点
    CGPoint point = [[touches anyObject] locationInView:self.mapView];
    
    
    // 2. 转换成经纬度
    CLLocationCoordinate2D pt = [self.mapView convertPoint:point toCoordinateFromView:self.mapView];
    
    // 3. 添加大头针
    [self addAnnoWithPT:pt];
    
   
    
}

//-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
//{

- (void)addAnnoWithPT:(CLLocationCoordinate2D)pt
{
    __block XMGAnno *anno = [[XMGAnno alloc] init];
    anno.coordinate = pt;
    anno.title = @"银江软件园";

    anno.type = arc4random_uniform(5);
    [self.mapView addAnnotation:anno];
    CLLocation *loc = [[CLLocation alloc] initWithLatitude:anno.coordinate.latitude longitude:anno.coordinate.longitude];
    [self.geoC reverseGeocodeLocation:loc completionHandler:^(NSArray * _Nullable placemarks, NSError * _Nullable error) {
        CLPlacemark *pl = [placemarks firstObject];
        anno.title = pl.locality;
        anno.subtitle = pl.thoroughfare;

    }];

    // 添加多个大头针
//    self.mapView addAnnotations:<#(nonnull NSArray> *)#>
    
    
}


#pragma mark - MKMapViewDelegate

-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    
}


/**
 *  当我们添加大头针模型时,
 *
 *  @param mapView    地图

 */
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation
{
//    return nil;
 
    static NSString *inden = @"datouzhen";
    MKAnnotationView *pin = [mapView dequeueReusableAnnotationViewWithIdentifier:inden];
    if (pin == nil) {
        pin = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:inden];
    }
    
    pin.annotation = annotation;
    
    // 设置是否弹出标注

    XMGAnno *anno = (XMGAnno *)annotation;
    NSString *imageName = [NSString stringWithFormat:@"category_%zd", anno.type + 1];
    pin.image = [UIImage imageNamed:imageName];

    
    // 设置大头针图片(系统大头针无效)

    return pin;
    
}

}



@end

四、利用系统App导航|3D视角|地图快照截图

#import "ViewController.h"
#import 



@interface ViewController ()

/**   */
@property (nonatomic, strong) CLGeocoder *geoC;
@property (weak, nonatomic) IBOutlet MKMapView *mapView;

@end

@implementation ViewController

{
    if (!_geoC) {

    }
    return _geoC;
}


- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
   
    // 3D视角
//    MKMapCamera *camer = [MKMapCamera cameraLookingAtCenterCoordinate:CLLocationCoordinate2DMake(23.132931, 113.375924) fromEyeCoordinate:CLLocationCoordinate2DMake(23.135931, 113.375924) eyeAltitude:10];
//    self.mapView.camera = camer;
    
    //地图快照截图
    MKMapSnapshotOptions *option = [[MKMapSnapshotOptions alloc] init];
    // 针对地图
    option.region = self.mapView.region;
    option.showsBuildings = YES;
    
    // 输出图片

            [data writeToFile:@"/Users/xiaomage/Desktop/map.png" atomically:YES];
        }else
        {
            NSLog(@"--%@", error.localizedDescription);
        }
       
        
        
    }];
}


- (void)begNav

            [self beginNavWithBpl:gzP andEndP:shP];
            
        }];
        
    }];
}

- (void)beginNavWithBpl:(CLPlacemark *)beginP andEndP:(CLPlacemark *)endP
{
    // 创建开始的地图项
    CLPlacemark *clPB = beginP;
    MKPlacemark *mkPB = [[MKPlacemark alloc] initWithPlacemark:clPB];

    // 启动字典
    NSDictionary *dic = @{
                          // 导航方式
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,

                          // 是否显示交通
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    
    [MKMapItem openMapsWithItems:items launchOptions:dic];

#import 
#import
