在应用开发中，经常会使用到显示地图的功能，地位功能，在ios中 使用MKMapVIew类显示地图， 使用MKMapView 前必须先导入MapKit.framework.

        点击项目target->summary 添加 Mapkit.framework.

       在ViewController.h头文件中导入 #import <MapKit/MapKit.h> 

#import 
    
     #import 
     
      #import 
      
       @interface ViewController : UIViewController@property (nonatomic,strong) MKMapView * myMapView;@end
      
     
    

       在ViewController.m 文件的viewDidLoad 方法中添加如下代码   

#import "ViewController.h"#import "MyAnnotation.h"@interface ViewController () 
    
     @end@implementation ViewController- (void)viewDidLoad{    [super viewDidLoad];	// Do any additional setup after loading the view, typically from a nib.    self.view.backgroundColor = [UIColor whiteColor];    self.myMapView = [[MKMapView alloc] initWithFrame:self.view.bounds];    self.myMapView.mapType = MKMapTypeHybrid;    self.myMapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;    self.myMapView.delegate = self;   //显示当前位置    self.myMapView.showsUserLocation = YES;    [self.view addSubview:self.myMapView];    }- (void)didReceiveMemoryWarning{    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{    return YES;}@end
    

MKMapView 地图类型mapType 属性 有三种类型：

enum {

    MKMapTypeStandard = 0,

    MKMapTypeSatellite,

    MKMapTypeHybrid

};

typedef NSUInteger MKMapType;
