How to get user input using cocos2d

I am looking to prompt the user to enter his/her name at the beginning of a game I am building.

What is the best way to get input from the user in cocos2d?

Thank you, Joey

Cocos2d doesn't have any text input controls but you can easily add UIKit controls to the scene in Cocos2d 2.0

[[CCDirector sharedDirector] view] addSubview:myTextField];

You can use a UIAlertView with a text field embedded.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Message" delegate:self cancelButtonTitle:@"Done" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
//[alert release]; If not using ARC

To receive the events back from the UIAlertView you implement the UIAlertViewDelegate. In your header file add the delegate protocol to your interface

@interface BTMyScene : CCLayer <UIAlertViewDelegate>

Then in your implementation file add any of the methods from the delegate protocol you want to receive notifications for. You probably want this one

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
     UITextField *textField = [alertView textFieldAtIndex:0];
     NSString *name = textField.text;
}

I recommend reading the documentation for UIAlertView and UIAlertViewDelegate. You will see all the available methods that you can use.
