Switch between OpenGL View and UIKit View

[Espuz]

Hello everyone, I'm new on his forum and I hope you can answer my question and help me to solve this problem. I have read many threads on this forum about questions like that but I don't understand several points.

Well, i'm developing a game on iPhone with OpenGL ES. I began my development few months ago using the Xcode template (SDK 2.1) OpenGL ES Application, with one EAGLView and an AppDelegate, etc.

My menu view and game view use the same OGL view with custom "abstract" views and transitions, so I didn't need more views. But now I want to add score ranking so I need a keyboard and a text field to write name, and some labels or a table view to show ranking.

I think that the best solution is to have my current OGL View with another UIKit View where I will put the score ranking and do the switching when necessary.

I have the Apress book Beginning iPhone Development and I follow the chapter about multiple views. I take the point of switching between two UIViewController but when I'm going to make changes in my game... glView is not a UIViewController, it's a UIView, so I'm lost.

I don't know how can I make a UIViewController of my current EAGLView, attach it to a nib, etc. Also, I don't know how the game works now because the MainWindow.xib doesn't have anything except window and app. delegate.

Yes, I'm very very lost Can anyone help me with this?

Thank you very much.

Well, I think I solved the problem, so I share the solution with you.

I started from the multiple views example from the book: three xib (main window and two views we switch), the app. delegate, two view controller for each view and a root view controller which switch between our views.

I added the EAGLView class and renderer to this project and changed the initWithCoder method on EAGLView to initWithFrame:

//- (id) initWithCoder:(NSCoder*)coder
- (id)initWithFrame:(CGRect)frame
{    
    if ((self = [super initWithFrame:frame])) {
    // The same we had.

Then, in my root view controller I have added an IBAction when I tap a button:

- (IBAction)drawEAGLView:(id)sender {
	CGRect rect = [[UIScreen mainScreen] applicationFrame];
	glView = [[EAGLView alloc] initWithFrame:CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height)];
	self.view = glView;
	[glView startAnimation];
}

And that's all. Very simple and it works well. Maybe it needs some optimization but this is a good start point.

So, I can make now my score ranking
