我正在使用以下代码进行反向地理编码

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

{

curLoc=newLocation;

if (curLoc != nil) {

latitude=curLoc.coordinate.latitude;

longitude=curLoc.coordinate.longitude;

//[self loadMap:latitude second:longitude];

[self MarkerPoint:latitude+0.04 second:longitude+0.1 third:latitude-0.04 forth:longitude-0.1];

NSError *error;

NSString *lookupString = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?latlng=%f,%f&sensor=false",latitude,longitude]];

NSLog(@"URL: %@",lookupString);

lookupString = [lookupString stringByReplacingOccurrencesOfString:@" " withString:@"+"];

NSData *jsonResponse = [NSData dataWithContentsOfURL:[NSURL URLWithString:lookupString]];

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonResponse options:kNilOptions error:&error];

self.locationArray = [[jsonDict valueForKey:@"results"] valueForKey:@"formatted_address"];

int total = self.locationArray.count;

NSLog(@"locationArray count: %d", self.locationArray.count);

for (int i = 0; i < total; i++)

{

NSString *statusString = [jsonDict valueForKey:@"status"];

NSLog(@"JSON Response Status:%@", statusString);

NSLog(@"Address: %@", [self.locationArray objectAtIndex:i]);

}

}

}

现在我收到此错误：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSURL stringByReplacingOccurrencesOfString:withString:]: unrecognized selector sent to instance 0xbce98c0'
