怎么使用Markdowm
寫的非常詳細(xì),拿過(guò)來(lái)借用一下,有想在簡(jiǎn)書發(fā)表文章的可以看看
[簡(jiǎn)書]http://www.reibang.com/p/q81RER/
簡(jiǎn)單的定位功能,并實(shí)現(xiàn)反地理編碼
.h的聲明
#import <CoreLocation/CoreLocation.h>
@interface ViewController ()<CLLocationManagerDelegate>
//位置管理者
@property(nonatomic,strong)CLLocationManager * locationManager;
///緯度
@property(nonatomic,assign)CLLocationDegrees coreLati;
///經(jīng)度
@property(nonatomic,assign)CLLocationDegrees coreLong;
///編碼者
@property(nonatomic,strong)CLGeocoder * geocoder;
@end```
####.m的實(shí)現(xiàn)
-(CLGeocoder *)geocoder{
if (_geocoder==nil) {
_geocoder = [[CLGeocoder alloc]init];
}
return _geocoder;
}
- (void)viewDidLoad {
[super viewDidLoad];
// [self reverseGeoCoder];
[self startLocationService];
}
pragma mark -- 開啟定位服務(wù)
-(void)startLocationService{
//確定用戶的位置服務(wù)啟用

NSLog(@"使用期間定位");
[self.locationManager requestWhenInUseAuthorization];
}
//開始定位的時(shí)候不斷更新位置
[self.locationManager startUpdatingLocation];
// }
}
pragma mark -- 獲取定位的位置
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
//獲取用戶的位置的對(duì)象

//停止更行

pragma mark -- 定位后反地理編碼

// 反地理編碼(經(jīng)緯度---地址)

//獲得的定位信息
NSString * str = pl.name;
//獲得緯度

//獲得省份(形成區(qū)域)
