I have a very simple game using Xcode v4.2.1, Cocos2d v5.0.1. I’ve tried both compilers in Xcode (LLVM GCC 4.2 and Apple LLVM compiler 3.0. Is there a preference??) On the game screen is a UIKit button that presents the user with a Interface Builder (nib) Settings/Options screen to customize the game a bit. This is all based on what I learned in Ray Wenderlich’s tutorial (http://www.raywenderlich.com/4817/how-to-integrate-cocos2d-and-uikit).

After the user makes their changes, they are returned to the game and the changes are in place.

This all works as I want in the simulator, however, when I test the game on an iPad I get the following errors in the debug window:

2012-01-27 18:25:27.305 BonkBonk[1082:707] failed to call context
2012-01-27 18:25:27.310 BonkBonk[1082:707] cocos2d: surface size: 1024x768
2012-01-27 18:25:27.316 BonkBonk[1082:707] Failed to make complete framebuffer object 8cdd
OpenGL error 0x0506 in -[EAGLView swapBuffers]
OpenGL error 0x0506 in -[EAGLView swapBuffers]
OpenGL error 0x0506 in -[EAGLView swapBuffers]

The OpeenGl errors continue on indefinitely.

I use the function viewWillAppear to capture the return from the settings/options screen so that I can pass the new settings to the game layer. If I comment out this code the problem goes away, however, I am not able to get the new user settings to the game layer.

Here is the code:

- (void) viewWillAppear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:YES animated:animated];
    //CCScene *scene = [[CCDirector sharedDirector] runningScene];
    CCScene *scene = [BonkBonkLayer scene];
    id layer = [scene getChildByTag:1];
    [layer userSettings];
    [super viewWillAppear:animated];
}

The commented out line //CCSene *scene… was another failed attempt at getting the layer object from the scene so that I could call the userSettings method where the game layer then can assimilate it into the game.

    OK, so I’ve found something that alleviates my issue.

    If anyone knows anything about this, please let me know. I will continue to use this fix unless I hear a reason from someone more knowledgable than myself (and that’s not that difficult).

    The solution is found in the comment by “psionic” at the end of the following discussion:
    http://www.cocos2d-iphone.org/forum/topic/7068.

    Basically, I created a static bool in the EAGLView class (EAGLView.m) that surrounds the call to _resizeFromLayer in the layoutSubViews member function. The call to _resizeFromLayer is only called the first time through, and then never again.

    Please read the above discussion and let me know what you like/dislike about this solution, other than the obvious… it’s a hack.

    A hack,that works. I think.
