Get driving direction in iPhone - iphone

Question

I read both iPhone and Google Map for iPhone EULA and want to implement a static driving direction map in my iPhone application (native).
I am finding a simple way to get route data and display with build-in route display feature in iOS 4 SDK' Mapkit.
Is there any programmer implement a feature like this with Google Map and Bing Map? Since Bing Map provided routing data in SOAP web service, it's seem easier to programming driving direction with Bing's service.

I found the solution for this. Just use a JSON parser to got google map API
For example:
NSDictionary *testJsondata = [self testJson:GoogleMapXMLDirectionQueryString];
NSLog(#"Here is the title of the response: %#", [testJsondata valueForKey:#"status"]);
for (id key in testJsondata) {
NSLog(#"key: %#, value: %#", key, [testJsondata objectForKey:key]);
}
}
- (NSDictionary *) testJson : (NSString*) url
{
id response = [self objectWithUrl:[NSURL URLWithString:url]];
NSDictionary *feed = (NSDictionary *)response;
return feed;
}
- (id) objectWithUrl:(NSURL *)url
{
SBJsonParser *jsonParser = [SBJsonParser new];
NSString *jsonString = [self stringWithUrl:url];
// Parse the JSON into an Object
return [jsonParser objectWithString:jsonString error:NULL];
}
- (NSString *)stringWithUrl:(NSURL *)url
{
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad
timeoutInterval:30];
// Fetch the JSON response
NSData *urlData;
NSURLResponse *response;
NSError *error;
// Make synchronous request
urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse: &response
error: &error];
// Construct a String around the Data from the response
return [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding];
}
- (NSString *)getDirectionInXML:(NSString *)GoogleMapXMLDirectionQueryString
{
NSError *error;
NSURLResponse *response;
NSData *dataReply;
NSString *stringReply;
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:
[NSURL URLWithString: [NSString stringWithFormat:GoogleMapXMLDirectionQueryString]]];
[request setHTTPMethod: #"GET"];
dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding];
return stringReply;
}
