URL decoding/encoding NSString

Question

I am using three20's URL navigator and I want to create a map as follows:

[map from:[Group class] name:@"show" toURL:@"tt://group/(gid)/(name)"];

The issue here name can be multiple words and so there is spaces in between. Now I need to URL encode this NSString and decode it back. How do I do this? What is the easiest way to URL decode and encode NSString?

- (NSString *)encodedURLString {
    NSString *result = (NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,(CFStringRef)self,
                                                                           NULL,                   
                                                                           CFSTR("?=&+"),          
                                                                           kCFStringEncodingUTF8); // encoding
    return [result autorelease];
}

- (NSString *)encodedURLParameterString {
    NSString *result = (NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
                                                                           (CFStringRef)self,
                                                                           NULL,
                                                                           CFSTR(":/=,!$&'()*+;[]@#?"),

    return [result autorelease];
}

You can start with

NSURL *url = [NSURL URLWithString:@"http://www.google.com"];

to get the url from the NSString.

Also, see here about URLencoding it with the proper escapes.
