   Hope this is not a very basic question but I have a problem with a UITextField that I use to allow a user to enter his/her user name. It works totally fine with one exception: eventhough the game is in landscape, the UITextField orientation is in Portrait. Not ideal

   I create the textfield like this:
   UITextField *playerTextField = [ [ UITextField alloc ] initWithFrame: CGRectMake(50, 50, 145, 38) ];
   playerTextField.adjustsFontSizeToFitWidth = YES;
   playerTextField.textColor = [UIColor blackColor];
   playerTextField.font = [UIFont systemFontOfSize:17.0];
   playerTextField.placeholder = @"";
   playerTextField.backgroundColor = [UIColor whiteColor];
   playerTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
   playerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
   playerTextField.textAlignment = UITextAlignmentLeft;
   playerTextField.keyboardType = UIKeyboardTypeDefault; // use the default type input method (entire keyboard)
   playerTextField.returnKeyType = UIReturnKeyDone;
   playerTextField.tag = 0;
   playerTextField.delegate = self;

   playerTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
   playerTextField.text = [[GameHUD sharedHUD] LocUserName];
   [ playerTextField setEnabled: YES ];

   [[[Director sharedDirector] openGLView] addSubview:playerTextField];
   [playerTextField release];

   Can anyone point me in the right direction how to show it in landscape?

   Thanks a lot!

   I believe I found a solution:

   playerTextField.bounds = CGRectMake(0, 0, 145, 38);
   playerTextField.transform = CGAffineTransformConcat(playerTextField.transform, CGAffineTransformMakeRotation(90 * degreesToRad));

   I'm trying to implement my own local high score system (because after 3 weeks, I still have no idea how to add cocosLive to my own game) and I was looking at this to capture the users name, but my game keeps complaining with:

   playerTextField.delegate = self;

   Warning 'GameLayer' does not implement the 'UITextFieldDelegate' protocol

   I am unsure how to procede. I copied the code as above with:

   playerTextField.text = [[GameHUD sharedHUD] LocUserName]; removed as it didnt fit my game.

   I'm already using a dialog box that uses [dialog setDelegate:self] and that is working fine.

   A protocol in objective-c is used to declare that your class implements certain methods.
   So in this case by implementing UITextFieldDelegate, the text field knows it can call various methods in your 'delegate' class when an event is triggered, and you can handle them however you like.

   To declare it you put it in '<' & '>' brackets in you classes declaration in the .h file, e.g.

   @interface GameLayer : Layer <UITextFieldDelegate> {
   }

   Then in you .m file you can implement any of the methods defined here, to handle those situations (for UITextFieldDelegate, it says their all optional).

   http://developer.apple.com/iPhone/library/documentation/UIKit/Reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html

   The code at the end of this tutorial shows some simple usage (ignore the IB bits earlier on)

   Hope that helps.

   Wow, thanks and fast... I'm sorry to make this a teaching hospital for the cocoa-inept, but I really am learning!

   I will look that over.

   Interesting, the dialog has always worked, but I do not have a <UIAlertViewDelegate> in GameLayer declaration.

   I haven't used an alert view, but perhaps you only need to implement the delegate protocol if you use custom buttons, or act on certain alert events. I'm guessing you didn't need to set 'alertView.delegate = self' when you used it?

   the example I based it one had that, so I used it. I'm still very green and do not understand most of this stuff, but my game is 99% finished and running @ 50-60fps with no leaks that I can find and allowing hours of gameplay without crashing, so I'm happy. But there is SO MUCH I still just don't get.

   I barely even know what a delegate is! If I make any money at all from this game, will be investing in some books, thats for sure!
