iOS--CoreLocation地理反地理编码

操作步骤

• 1.导入框架

CoreLocation/CoreLocation.h

• 2.设置属性

@property (nonatomic, strong) CLGeocoder *geocoder;

• 3.方法实现

3.1 懒加载创建geocoder属性

- (CLGeocoder *)geocoder
{
    if (!_geocoder) {
        self.geocoder = [[CLGeocoder alloc] init];
    }
    return _geocoder;
}

3.2 地理编码

//地理
- (void)dili
{
    //地理编码方法

    NSString *straddress = @"北京";

    [self.geocoder geocodeAddressString:straddress completionHandler:^(NSArray *placemarks, NSError *error) {
        if (error) { // 有错误
            NSLog(@"找不到该地址");
        } else { // 编码成功

            // 取出最前面的地址
            CLPlacemark *pm = [placemarks firstObject];

            // 取出经纬度
            CGFloat  latitude = pm.location.coordinate.latitude;
            CGFloat longitude =  pm.location.coordinate.longitude;

            //NSLog(@"总共找到%d个地址", placemarks.count);

            for (CLPlacemark *pm in placemarks) {
                NSLog(@"-----地址开始----");

                NSLog(@"%f %f %@", pm.location.coordinate.latitude, pm.location.coordinate.longitude, pm.name);

                [pm.addressDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
                    NSLog(@"%@ %@", key, obj);
                }];

                NSLog(@"-----地址结束----");
            }
        }
    }];
}

3.3 反地理编码

//反地理
- (void)fandili
{
    //反地理编码

    // 1.位置
    CLLocationDegrees latitude = 114.0;
    CLLocationDegrees longitude = 45.0;
    CLLocation *loc = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];

    // 2.反地理编码
    [self.geocoder reverseGeocodeLocation:loc completionHandler:^(NSArray *placemarks, NSError *error) {
        if (error) { // 有错误（地址乱输入）
            NSLog(@"找不到该地址");
        } else { // 编码成功
            // 取出最前面的地址
            CLPlacemark *pm = [placemarks firstObject];
            NSLog(@"%@", pm.name);
            // 设置具体地址

            NSLog(@"总共找到%ld个地址", (long)placemarks.count);

            for (CLPlacemark *pm in placemarks) {
                NSLog(@"-----地址开始----");

                NSLog(@"%f %f %@", pm.location.coordinate.latitude, pm.location.coordinate.longitude, pm.name);

                [pm.addressDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
                    NSLog(@"%@ %@", key, obj);
                }];

                NSLog(@"-----地址结束----");
            }
        }
    }];
}

3.4 调用方法

- (void)viewDidLoad {
    [super viewDidLoad];

    [self dili];
    [self fandili];
}
