Detect if NSString contains a URL and generate a "link" to open inside the app a Safari View

Question

I have am reading a twitter feed in my iPhone application and can do it correctly, but I'd like to evolve it in a way to detect if the whole NSString contains any URL or URLs and create a "link" that will open a UIWebView within the same application.

Can you guide me on how to perform this task?

-(void) setTextTwitter:(NSString *)text WithDate:(NSString*)date
{
    [text retain];
    [textTwitter release], textTwitter = nil;
    textTwitter = text;

    [date retain];
    [dateTwitter release], dateTwitter = nil;
    dateTwitter = date;

    [self setNeedsDisplay];
}

Hey Cy,

Check out Craig Hockenberry's IFTweetLabel, which can be found here.

Or you can use the label provided by Three20 library, which can be found here.

Or the simplest solution: use UIWebView with dataDetectorTypes set to UIDataDetectorTypeLink.
