Using Shrty

This simple example assumes a few things.
1) _shrty is a member variable.
2) shrtySvcWithName - We're creating a service instance that doesn't require a name or password. (E.G. IsGd)
3) self implements the ShrtyDelegateProtocol protocol.

First things first.

#import "Shrty.h"

Shrty.h will include everything you need to use Shrty.

Next you'll need to create a ShrtySvc instance. The code below illustrates how you may choose to do that. In this case we're passing the service name, Is.Gd, into a helper method to create our instance. There are constants defined in ShrtySvcConst.h for all the services supported by Shrty.


// Go create an instance of the IsGd service.
[self _createShrtyInstanceFromServiceName:kShrtyIsGdSvcName];
if (nil != _shrty)
{
	NSString* urlToShorten = @"http://rob.crabapples.net/";
		
	// Shorten the URL.
	[_shrty shortenUrl:urlToShorten];
}

In the example above I've removed some code for brevity's sake. Another thing to note is use of the helper method _createShrtyInstanceFromServiceName, included below. This method is part of ShrtyAppController.m, you'll find it in the Shrty source, it's part of the test project.


- (void)_createShrtyInstanceFromServiceName:(NSString*)serviceName
{
	[_shrty release];
	
	_shrty = [ShrtySvc shrtySvcWithName:serviceName userName:nil userPassword:nil delegate:self];
}

If all goes as expected you should expect to receive a callback to your didReceiveShortenedURL method.


- (void) didReceiveShortenedURL:(NSString*)shortenedURL 
	resultCode:(NSString*)resultCode
{
	if (nil == shortenedURL)
	{
		NSLog(@"GOT A NIL RESULT, DOH!");
	}
	else
	{
		NSLog(shortenedURL);
	}
}
