Problem with textfields and scene transition + cocos2d

I am having problems with my textfield not flowing with the scene transistion. Basically my scene is transition with this call:

Scene* gs = [[[QuestionsScene alloc] initWithPage:2] autorelease];
[[Director sharedDirector] replaceScene: [SlideInRTransition transitionWithDuration:0.5 scene: gs]];

However in my init i have a textfield called here:

[answerBox setTextColor:[UIColor blackColor]];
[answerBox setTextAlignment:UITextAlignmentLeft];
[answerBox setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];
[answerBox setClearsOnBeginEditing:YES];
[answerBox setBorderStyle:UITextBorderStyleRoundedRect]; 

[answerBox setDelegate:self];
[answerBox setReturnKeyType:UIReturnKeyDone];
[answerBox setAutocapitalizationType:UITextAutocapitalizationTypeWords];
[[[Director sharedDirector] openGLView] addSubview: answerBox];

The textbox does not follow the transition, it just sits there into the next scene. Anyone have an idea on how intergrate the textfield into the transition?

from your exmaple in http://www.cocos2d-iphone.org/forum/topic/2415

was this method define in the layer class?
-(void)setPosition:(CGPoint)pos {

[super setPosition:pos];

CGRect frame = slider.frame;
frame.origin.y = frame.origin.y + ([self position].y - pos.y);
slider.frame = frame;

}

Or you just created a class which contain an object slider?

It was defined in the layer I was moving. Although I wasn't using it with scene transitions, this was just for a custom menu 'overlay' layer, that slides in and out of view. Eshirt seemed to have issues trying to make it work for scene transitions.

It may be worth trying crmagicxxx's idea using "standard beginAnimations/commitAnimations block to simulate your sliding transition". Or perhaps ask eshirt if he found a way round it.

good luck!

Still haven't found a way around it. :)

But I haven't tried writing the core animation methods that crmagicxxx mentioned. I'll be working on this a bit over the next couple days - so if I figure it out, I'll update it here.

OK I added beginAnimation which seems to simulate an animation, here's the code fragmant on how i did this:

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.5];
[[[Director sharedDirector] openGLView] addSubview: answerBox];

Basically, it scales it up on default. However, what I am trying to do is have it slide from left to right like how SlideInRTransition in replace scene does it:

[[Director sharedDirector] replaceScene: [SlideInRTransition transitionWithDuration:0.5 scene: gs]];

I am looking for transition in this code fragment for this effect but I can't find anything:
[UIView setAnimationTransition:UIViewAnimationCurveEaseInOut forView:[[Director sharedDirector] openGLView] cache:YES];

I'm unfortunately still struggling with this. To make things more complicated, I'm using the FlipXTransition to simulate the "screen flip" for the setting screen.

My UISwitches and UISliders still just pop in/out. Here's what I was trying to use, but it's not working at all. I'd be happy if I could just get them to fade in, but ideally, I'd like them to flip with the transition.
```
[UIView beginAnimations:nil context:NULL];
	[UIView setAnimationDuration:0.25f];
	[UIView	setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:[[Director sharedDirector] openGLView] cache:YES];
	[[[[Director sharedDirector] openGLView] window] addSubview: vibrationSwitch];

	[UIView commitAnimations];
```
Has anyone else had success with this? I tried reading through the "Integrating UIKitLayer" section in the documentation and for the most part, I was completely lost...

Ok, I decided to ditch the flip transition in favor of a SlideInRTransition.

@fchan, you could use this to animate your answerbox:

-(void) onEnter
{

	for( id child in children )
		[child onEnter];

	[self activateTimers];

	isRunning = YES;

	[[[[Director sharedDirector] openGLView] window] addSubview: answerbox];

	answerbox = CGAffineTransformTranslate(answerbox, 320, 0);
	[UIView beginAnimations:nil context:NULL];
	[UIView setAnimationDuration:.25f];
	answerbox = CGAffineTransformMakeRotation(M_PI/2);
	[UIView commitAnimations];

}
