Question

我正在尝试使用方法将我的lat long转换为地址：

#pragma mark:convert latLong to address
-(void)getMerchantAddress:(NSDictionary *)dict
{

    double lata = [[dict valueForKey:@"user_lat"] doubleValue];
    double longa = [[dict valueForKey:@"user_long"] doubleValue];

    NSLog(@"%f",lata);
    NSLog(@"%f",longa);

    CLLocation *LocationAtual = [[CLLocation alloc]initWithLatitude:lata longitude:longa];


    CLGeocoder *geocoder = [[CLGeocoder alloc] init];

    [geocoder reverseGeocodeLocation:LocationAtual completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if(placemarks && placemarks.count > 0)
         {
             CLPlacemark *placemark= [placemarks objectAtIndex:0];
             NSArray *lines = placemark.addressDictionary[ @"FormattedAddressLines"];
             NSString *addressString = [lines componentsJoinedByString:@","];
             _usrtAddressLbl.text = addressString;
             _userAddressLbl.text = addressString;
         }
     }];
}

我的应用程序崩溃@ point

[geocoder reverseGeocodeLocation:LocationAtual completionHandler:^(NSArray *placemarks, NSError *error)

显示错误：

[__NSCFNumber rangeOfCharacterFromSet:]: unrecognized selector sent to instance 0xb000000000005f53

我该如何解决它。提前谢谢。

试试这个为我工作

-(void)getMerchantAddress:(NSDictionary *)dict
{


    float lata = [[dict objectForKey:@"user_lat"] floatValue];
    float longa = [[dict objectForKey:@"user_long"] floatValue];

    CLGeocoder *ceo = [[CLGeocoder alloc]init];
    CLLocation *loc = [[CLLocation alloc]initWithLatitude:lata longitude:longa]; //insert your coordinates

    [ceo reverseGeocodeLocation:loc
              completionHandler:^(NSArray *placemarks, NSError *error) {
                  CLPlacemark *placemark = [placemarks objectAtIndex:0];
                  if (placemark) {

                      NSLog(@"placemark %@",placemark);
                      //String to hold address
                      strAddress = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
                      NSLog(@"addressDictionary %@", placemark.addressDictionary);

                  }else {

                  }
              }
     ];
}
