地图与定位之地理编码

定位学习之后学习地理编码和反编码。

#import "ViewController.h"

#import <CoreLocation/CoreLocation.h>





@interface ViewController ()<CLLocationManagerDelegate>



@property(nonatomic,strong)CLGeocoder *cLGeocoder;



@end



@implementation ViewController



- (void)viewDidLoad {

    [super viewDidLoad];

    NSString *address=@"天安门";

    CLLocation *clLocation=[[CLLocation alloc]initWithLatitude:39.54 longitude:116.28];

    _cLGeocoder=[[CLGeocoder alloc]init];

    

    

    //编码

    [_cLGeocoder geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error) {

        CLPlacemark *placemark=[placemarks firstObject];
