iOS——地圖的使用

蘋果開發自帶地圖，可以直接使用，如果需要經緯度定位，或者擷取其他坐标資訊，還可以接入定位的一些代碼，參考連結：http://blog.csdn.net/w582324909/article/details/53610374

1、首先info.plist檔案請求授權：

2、導入庫：

3、導入頭檔案：

#import <MapKit/MapKit.h>

4代碼部分：

@interface MapViewController ()<MKMapViewDelegate,CLLocationManagerDelegate>

@property (nonatomic) CLLocationCoordinate2D centerCoordinate;
@property (nonatomic) MKCoordinateRegion region;
@property (nonatomic, strong) CLLocationManager* locationMgr;

@property (nonatomic, strong) CLLocation* coordinate;

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

@end

@implementation MapViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    [self createButton];
    
    self.locationMgr.distanceFilter = 10.0f;
    self.map.showsUserLocation = YES;
    self.map.mapType = MKMapTypeStandard;
}

-(void)createButton
{
    UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(50, self.view.frame.size.height - 100, 30, 30)];
    [btn setImage:[UIImage imageNamed:@"location.png"] forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
    [self.map addSubview:btn];//button的作用是點一下，可以回到目前的位置，類似于找到自己的功能。
}

-(void)back
{
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(self.centerCoordinate, 250, 250);
    [self.map setRegion:region animated:YES];
}

//MapView委托方法，當定位自身時調用
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    CLLocationCoordinate2D loc = [userLocation coordinate];
    self.centerCoordinate = loc;
    //    放大地圖到自身的經緯度位置。
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(loc, 250, 250);
    [self.map setRegion:region animated:YES];//有動畫
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

@end
           

tip：用到地圖、定位的時候盡量使用真機測試~
