需要准备工作按照下图引进类库
需要添加
添加的两个字符串为:NSLocationWhenInUseUsageDescription / NSLocationAlwaysUsageDescription
默认定位设置:
设置工作准备完毕上代码:
指示根视图:
[objc]view plaincopy [[UINavigationBarappearance]setBarTintColor:[UIColorcolorWithRed:23/255.0green:180/255.0blue:237/255.0alpha:1]];self.window.rootViewController=[MapViewControllernew];
MapViewController.m//设置需要的属性
[objc]view plaincopy #import"MapViewController.h"#import<MapKit/MapKit.h>#import"Mypoint.h"#import<CoreLocation/CoreLocation.h>@interfaceMapViewController()<MKMapViewDelegate,CLLocationManagerDelegate>@property(nonatomic,strong)MKMapView*mapView;//经度@property(nonatomic,strong)UITextField*longitudetext;//纬度@property(nonatomic,strong)UITextField*latitudeText;//经度@property(nonatomic,strong)UILabel*longitudeLabel;//纬度@property(nonatomic,strong)UILabel*latitudelabel;//防止标注的button[@property(nonatomic,strong)UIButton*button;//地址输入@property(nonatomic,strong)UITextField*destination;//输入地址查询地图@property(nonatomic,retain)UIButton*searchButton;//可以获取设备当前的经纬度信息@property(nonatomic,strong)CLLocationManager*locManager;@end@implementationMapViewController
调用:

[objc]view plaincopy -(void)countDistance{CLLocation*loc1=[[CLLocationalloc]initWithLatitude:34longitude:113];CLLocation*loc2=[[CLLocationalloc]initWithLatitude:35longitude:113];CLLocationDistancedistance=[loc1distanceFromLocation:loc2];NSLog(@"(%@)和(%@)的距离为:%f",loc1,loc2,distance);}
#pragma mark - CLLocationManagerDelegate Methods
// 此方法会被频繁调用
[objc]view plaincopy -(void)locationManager:(CLLocationManager*)managerdidUpdateLocations:(NSArray*)locations{//NSLog(@"didUpdateLocations---%lu",(unsignedlong)locations.count);//用来表示某个位置的地理信息,比如经纬度,海拔等等CLLocation*location=locations.lastObject;//location.coordinate.latitude维度//location.coordinate.longitude经度NSLog(@"经度==%f,维度==%f",location.coordinate.longitude,location.coordinate.latitude);self.longitudetext.text=[NSStringstringWithFormat:@"%f",location.coordinate.longitude];self.latitudeText.text=[NSStringstringWithFormat:@"%f",location.coordinate.latitude];//停止更新位置(不用定位服务时马上停止,因为非常耗电)//[managerstopUpdatingLocation];}
//调出地图
[objc]view plaincopy -(void)setMapView{//创建地图视图,初始化参数//MKMapTypeStandard显示街道和道路//MKMapTypeSatellite显示卫星//MKMapTypeHybrid显示混合地图self.mapView=[[MKMapViewalloc]initWithFrame:CGRectMake(0,100,320,460)];[self.mapViewsetMapType:MKMapTypeStandard];//显示用户当前的坐标,打开地图有相应的提示self.mapView.showsUserLocation=YES;//设置地图代理self.mapView.delegate=self;[self.viewaddSubview:self.mapView];}
#pragma mark 根据输入的经纬度确定位置
//放置标注

#pragma mark 根据输入的地址搜寻位置
//根据地址输入搜索地图
[objc]view plaincopy //根据地址输入搜索地图-(void)detailSearchAction:(UIButton*)search{if(_destination.text==nil||[_destination.textlength]==0){return;}CLGeocoder*geocode=[[CLGeocoderalloc]init];[geocodegeocodeAddressString:_destination.textcompletionHandler:^(NSArray*placemarks,NSError*error){if(error||placemarks.count==0){NSLog(@"地址不存在");}else{for(CLPlacemark*placemarkinplacemarks){NSLog(@"name=%@locality=%@country=%@postalCode=%@",placemark.name,placemark.locality,placemark.country,placemark.postalCode);}CLPlacemark*firstPlacemark=[placemarksfirstObject];CLLocationDegreeslatitude=firstPlacemark.location.coordinate.latitude;CLLocationDegreeslongitude=firstPlacemark.location.coordinate.longitude;//显示经纬度self.latitudeText.text=[NSStringstringWithFormat:@"%.2f",latitude];self.longitudetext.text=[NSStringstringWithFormat:@"%.2f",longitude];[selfshowLocation];[selfsearchDetailLocationAction];}}];}
//根据地址搜寻位置
[objc]view plaincopy //根据地址搜寻位置-(void)searchDetailLocationAction{//创建CLLocation设置经纬度CLLocationCoordinate2Dlocation=CLLocationCoordinate2DMake([self.latitudeText.textfloatValue],[self.longitudetext.textfloatValue]);//创建标题NSString*title=[NSStringstringWithFormat:@"%f,%f",[self.latitudeText.textfloatValue],[self.longitudetext.textfloatValue]];Mypoint*myPoint=[[Mypointalloc]initWithCoordinate:locationandTitle:title];//添加标注[self.mapViewaddAnnotation:myPoint];//放大到标注的位置MKCoordinateRegionregion=MKCoordinateRegionMakeWithDistance(location,0.01,0.01);[self.mapViewsetRegion:region];}
建一个类: [objc]view plaincopy //.h#import<Foundation/Foundation.h>#import<MapKit/MapKit.h>@interfaceMypoint:NSObject<MKAnnotation>//实现MKAnnotion协议必须要定义这个属性@property(nonatomic,readonly)CLLocationCoordinate2Dcoordinate;//标题@property(nonatomic,copy)NSString*title;//初始化方法-(id)initWithCoordinate:(CLLocationCoordinate2D)candTitle:(NSString*)t;@end [objc]view plaincopy //.m#import"Mypoint.h"@implementationMypoint//初始化方法-(id)initWithCoordinate:(CLLocationCoordinate2D)candTitle:(NSString*)t{if(self=[superinit]){_coordinate=c;_title=t;}returnself;}@end
