How to get user input using cocos2d

Question

I want to prompt the user to enter his name at the beginning of the game that I am creating.

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

Thanks Joey

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

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

You can use UIAlertView with an embedded text box.

 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 events from a UIAlertView, you implement a 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 for which you want to receive notifications. You probably need this

 - (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.
