地图简单事例代码

一:百度地图

1.按照API文档导入相应的库

2.AppDelegate文件

#import "BMapKit.h"

BMKMapManager* _mapManager;

    _mapManager = [[BMKMapManager alloc]init];
    BOOL ret = [_mapManager start:@"please enter your key" generalDelegate:self];
    
    if (!ret) {
        NSLog(@"manager start failed!");
    }

3.对应的viewController文件

#import "MapViewController.h"
#import "BMapKit.h"
#import "MyAnontation.h"

@interface MapViewController ()<BMKMapViewDelegate>
{
    BMKMapView *_mapView;

}
@end

@implementation MapViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self createBackBtn];
    self.view.backgroundColor = [UIColor whiteColor];
    _mapView=[[BMKMapView alloc]initWithFrame:self.view.bounds];
    [self.view addSubview:_mapView];
    [_mapView viewWillAppear];
    
    _mapView.centerCoordinate=CLLocationCoordinate2DMake(_cinemaModel.latitude.doubleValue, _cinemaModel.longitude.doubleValue);
    _mapView.delegate=self;
    _mapView.zoomLevel=14;
    
    //BMKPointAnnotation *annotation=[[BMKPointAnnotation alloc]init];
    //annotation.coordinate=_mapView.centerCoordinate;
    //[_mapView addAnnotation:annotation];
    
    CLLocationCoordinate2D coord;
    coord.longitude=[_cinemaModel.longitude doubleValue];
    coord.latitude=[_cinemaModel.latitude doubleValue];
    
    //自定义一个大头针
    MyAnontation *anontation=[[MyAnontation alloc] initWithCoor:coord title:_cinemaModel.name subTitle:_cinemaModel.addr];
    //大头针的编号
    //anontation.anonIndex=i;
    //添加到地图上(使用添加大头针的方法,不是添加控件)
    [_mapView addAnnotation:anontation];
}

#pragma mark --BMKMapViewDelegate代理----
- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation
{
    BMKAnnotationView *view=[[BMKAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"annotation"];
    view.image=[UIImage imageNamed:@"mark"];
    return view;
}

 二:高德地图

1.AppDelegate设置key值（高德后台注册）

#import <MAMapKit/MAMapKit.h>

[MAMapServices sharedServices].apiKey = (NSString *)key;

2.对应的viewController文件

#import "MAMapViewController.h"
#import <MAMapKit/MAMapKit.h>

@interface MAMapViewController ()<MAMapViewDelegate>
{
    MAMapView *_mapView;
}
@end

@implementation MAMapViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self createBackBtn];
    self.view.backgroundColor = [UIColor whiteColor];
    _mapView=[[MAMapView alloc]initWithFrame:self.view.bounds];
    _mapView.delegate  =self;
    _mapView.centerCoordinate = CLLocationCoordinate2DMake( _cinemaModel.latitude.doubleValue, _cinemaModel.longitude.doubleValue);
    //_mapView.showsUserLocation = YES;
    //[_mapView setUserTrackingMode:MAUserTrackingModeFollow];
    [self.view addSubview:_mapView];
    
    MAPointAnnotation *annotation = [[MAPointAnnotation alloc] init];
    annotation.coordinate = CLLocationCoordinate2DMake(_cinemaModel.latitude.doubleValue, _cinemaModel.longitude.doubleValue);
    //NSLog(@"%f---%f",_cinemaModel.latitude.doubleValue, _cinemaModel.longitude.doubleValue);
    annotation.title = _cinemaModel.name;
    annotation.subtitle = _cinemaModel.addr;
    [_mapView addAnnotation:annotation];
}

#pragma mark --MAMapViewDelegate代理----
-(MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation
{
    static NSString *annoId = @"PointAnnotation";
    MAAnnotationView *view = [mapView dequeueReusableAnnotationViewWithIdentifier:annoId];
    if (!view) {
        view = [[MAAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:annoId];
        view.draggable = YES;
        view.canShowCallout = YES;
        view.image = [UIImage imageNamed:@"mark"];
    }
    return view;
}

三:自定制大头针

1.头文件

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

//自定义大头针(必须具备系统大头针的属性)
@interface MyAnontation : NSObject <BMKAnnotation>

//大头针的编号
@property (nonatomic,assign) NSInteger anonIndex;


//重新实现一个初始化方法
-(instancetype) initWithCoor:(CLLocationCoordinate2D ) coor title:(NSString *) title subTitle:(NSString *) subtitle;

@end

2.对应的.m文件

#import "MyAnontation.h"

@implementation MyAnontation
{
    //经纬度
    CLLocationCoordinate2D _coor;
    
    //主标题
    NSString *_title;
    
    //副标题
    NSString *_subTitle;
}
-(instancetype) initWithCoor:(CLLocationCoordinate2D)coor title:(NSString *)title subTitle:(NSString *)subtitle
{
    self=[super init];
    if (self)
    {
        _coor=coor;
        _title=title;
        _subTitle=subtitle;
    }
    return self;
}

#pragma mark-MKAnontation

-(CLLocationCoordinate2D) coordinate
{
    return _coor;
}

-(NSString *) title
{
    return _title;
}

-(NSString *) subtitle
{
    return _subTitle;
}
@end
