    webView.scalesPageToFit=YES;
    NSString *mapurl = @"http://maps.google.com/maps?q=";
    NSString *urlString1 = [mapurl stringByAppendingFormat:@"America"];    
    NSString *OmitSpace = [urlString1 stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

    NSURL *url=[NSURL URLWithString:OmitSpace];
    NSURLRequest *requestObj=[NSURLRequest requestWithURL:url];

Another solution is to use googleapis's to find the latitude and longitude to the api's JSON response and use them in MKMapView to show that particular region..

An example..

http://maps.googleapis.com/maps/api/geocode/json?address=america&sensor=true

The result is JSON output where you can then fetch the Latitude and Longitude,further subjecting it to the MKMapView

or for iOS 5 and above use CLGeocoder and MKMapView to get the same output

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder geocodeAddressString:@"America" completionHandler:^(NSArray *placemarks, NSError *error) {
        //Error checking

        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        MKCoordinateRegion region;
        region.center.latitude = placemark.region.center.latitude;
        region.center.longitude = placemark.region.center.longitude;
        MKCoordinateSpan span;
        double radius = placemark.region.radius / 1000; // convert to km

        NSLog(@"Radius is %f", radius);
        span.latitudeDelta = radius / 112.0;

        region.span = span;

        [mapView setRegion:region animated:YES];
    }];

NSString *OmitSpace = [urlString1 stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

This will omit the whitespace only. It will not convert other escape characters. So replace above line with this.

NSString *OmitSpace = [urlString1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
