How to let the user fill the rest of the url link in xcode?

Question

I am working with xcode and I'm stuck in writing URL links. I want the user to fill the rest of my written URL code.

Here's the code:

- (IBAction)openURL:(id)sender { [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://facebook.com/....."]]; }

The user will see this: facebook.com/write your address here...

The "facebook.com/" part is a label and the "write your address here..." a textfield that is filled in the apps settings. For example I can write "JJMLS" in settings, so the result is "facebook.com/JJMLS".

I have sat a custom/invisibile "openURL" button over the result area.

How can I tell xcode that @"http://facebook.com/(.....)" part is an area that should get the JJMLS result when the user fills it???

I will really appreciate some help!

Try something like this:

- (IBAction)openURL:(id)sender {

    if(textfield.text == nil){

        UIAlertView *noTextAlert = [UIAlertView initWithTitle: @"No text entered!"
                                                      message: @"Please enter some text"
                                                     delegate: self
                                            cancelButtonTitle: @"Ok"
                                            otherButtonTitles: nil];

        [noTextAlert show];
    }

    else{

        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://facebook.com/%@", textfield.text]]]; 
    }
}

If you have any questions about the code, just put it in the comments. Hope this helps!
