一翻伺、mapkit的基本使用
#import "ViewController.h"
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
@interface ViewController ()
@property (weak, nonatomic) IBOutlet MKMapView *mapView;
/** */
@property (nonatomic, strong) CLLocationManager *lM;
@end
@implementation ViewController
- (CLLocationManager *)lM
{
if (!_lM) {
_lM = [[CLLocationManager alloc] init];
if ([_lM respondsToSelector:@selector(requestAlwaysAuthorization)])
{
[_lM requestAlwaysAuthorization];
}
}
return _lM;
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
/**
MKMapTypeStandard = 0,
MKMapTypeSatellite,
MKMapTypeHybrid,
MKMapTypeSatelliteFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
MKMapTypeHybridFlyover NS_ENUM_AVAILABLE(10_11, 9_0),
*/
// self.mapView.mapType = MKMapTypeSatelliteFlyover;
// self.mapView.zoomEnabled = NO;
//
//// self.mapView.showsCompass = NO;
// self.mapView.showsScale = YES;
[self lM];
// self.mapView.showsUserLocation = YES;
self.mapView.userTrackingMode = MKUserTrackingModeFollowWithHeading;
}
@end
二、mapkit的中級(jí)使用
#import "ViewController.h"
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
@interface ViewController ()<MKMapViewDelegate>
@property (weak, nonatomic) IBOutlet MKMapView *mapView;
/** */
@property (nonatomic, strong) CLLocationManager *lM;
@end

{
if (!_lM) {

if ([_lM respondsToSelector:@selector(requestAlwaysAuthorization)])
{
[_lM requestAlwaysAuthorization];
}
}
return _lM;
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
/**
MKMapTypeStandard = 0,
MKMapTypeSatellite,
MKMapTypeHybrid,
MKMapTypeSatelliteFlyover NS_ENUM_AVAILABLE(10_11, 9_0),

*/
// self.mapView.mapType = MKMapTypeSatelliteFlyover;
// self.mapView.zoomEnabled = NO;
//
//// self.mapView.showsCompass = NO;
// self.mapView.showsScale = YES;
[self lM];
self.mapView.delegate = self;
self.mapView.showsUserLocation = YES;
// self.mapView.userTrackingMode = MKUserTrackingModeFollowWithHeading;
}
#pragma mark - MKMapViewDelegate
/**
* 更新到位置
*
* @param mapView 地圖
* @param userLocation 位置對(duì)象
*/
-(void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
/**
* MKUserLocation (大頭針模型)
*
*
*/
userLocation.title = @"銀江軟件園";
userLocation.subtitle = @"城市寶";
// 設(shè)置地圖顯示中心
// [self.mapView setCenterCoordinate:userLocation.location.coordinate animated:YES];
// 設(shè)置地圖顯示區(qū)域

}
三虹统、大頭針的添加
