IOSMapKit如何快速入门？下面我来写一个简单的Demo，做简要介绍。
效果图：
操作步骤：
1.首先创建一个项目，在xib的view中添加一个MapVIew控件，并且导入MapKit.framework和CoreLocation.frameword框架。
2.实现ViewController的代码：
ViewController.h:
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
@interface DXWViewController : UIViewController<CLLocationManagerDelegate>
@property (retain, nonatomic) IBOutlet MKMapView *mapview;
@property(retain,nonatomic)CLLocationManager *manager;
@property(retain,nonatomic)CLLocation *location;
@property (retain, nonatomic) IBOutletCollection(UILabel) NSArray *labels;
@end
ViewController.m:
#import "DXWViewController.h"
#import "Place.h"
@interface DXWViewController ()
@end
@implementation DXWViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.manager = [[CLLocationManager alloc] init];
self.manager.delegate = self;
//精度
self.manager.desiredAccuracy = kCLLocationAccuracyBest;
[self.manager startUpdatingLocation];
self.mapview.showsUserLocation = YES;
}
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
self.location = [locations objectAtIndex:0];
[self.labels[0] setText:[NSString stringWithFormat:@"%f\u00B0",self.location.coordinate.longitude]];
[self.labels[1] setText:[NSString stringWithFormat:@"%f\u00B0",self.location.coordinate.longitude]];
[self.labels[2] setText:[NSString stringWithFormat:@"%gm",self.location.horizontalAccuracy]];
[self.labels[3] setText:[NSString stringWithFormat:@"%gm",self.location.altitude]];
[self.labels[4] setText:[NSString stringWithFormat:@"%gm",self.location.verticalAccuracy]];
Place *place = [[Place alloc] init];
place.coordinate = self.location.coordinate;
place.title = @"Title";
place.subtitle = @"subTitle";
[self.mapview addAnnotation:place];
//设置精度范围
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(place.coordinate, 1000, 1000);
[self.mapview setRegion:region animated:YES];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
- (void)dealloc {
[_mapview release];
[_labels release];
[super dealloc];
}
@end
3.创建大头针的类：
Place.h:
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
@interface Place : NSObject<MKAnnotation>
@property(copy,nonatomic)NSString *title;
@property(copy,nonatomic)NSString *subtitle;
@property(assign,nonatomic)CLLocationCoordinate2D coordinate;
@end
