MapKit的使用显示当前位置

1.添加MapKit.framework框架 ,在plist中添加字段,用于,获取用户当前位置设置

NSLocationAlwaysUsageDescription

2.代码

#import "ViewController.h"

#import <MapKit/MapKit.h>

@interface ViewController ()<MKMapViewDelegate>

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

//位置信息

@property(nonatomic,strong)CLLocation*location;

//地理编码对象

@property(nonatomic,strong)CLGeocoder*geocide;

@property(nonatomic,strong)CLLocationManager*manager;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

//地图显示的类型

//MKMapTypeStandard:标准类型

//MKMapTypeSatellite:卫星模型

//MKMapTypeHybrid:混合模型

self.mapKit.mapType=MKMapTypeStandard;

//    ios8中追踪用户位置

if([[UIDevice currentDevice].systemVersion doubleValue]>8.0)

{

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

[self.manager requestAlwaysAuthorization];

}

//设置不允许地图旋转

self.mapKit.rotateEnabled=NO;

self.mapKit.delegate=self;

//设置mapKit获取用户位置的方式

//    MKUserTrackingModeNone 不追踪

//    MKUserTrackingModeFollow 追踪

//    MKUserTrackingModeFollowWithHeading 追踪并获取用户的方向

self.mapKit.userTrackingMode=MKUserTrackingModeFollowWithHeading;

}

-(CLGeocoder*)geocide

{

if (_geocide==nil) {

_geocide=[[CLGeocoder alloc]init];

}

return _geocide;

}

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

{

//利用地理编码获取位置,设置标题

[self.geocide reverseGeocodeLocation:userLocation.location completionHandler:^(NSArray *placemarks, NSError *error) {

CLPlacemark *mark=[placemarks firstObject];

userLocation.title=mark.name;

userLocation.subtitle=mark.locality;

}];

//利用地图当前的位置设置显示的区域

CLLocationCoordinate2D center=userLocation.location.coordinate;

//指定纬度的跨度

MKCoordinateSpan span=MKCoordinateSpanMake(0.009310,0.007812);

//指定显示区域的中

MKCoordinateRegion region=MKCoordinateRegionMake(center, span);

//设置显示区域

[self .mapKit setRegion:region];

}

-(void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated

{

//地图区域改变完成

NSLog(@"%f,%f",self.mapKit.region.span.latitudeDelta,self.mapKit.region.span.longitudeDelta);

}

@end
