Answer 1

This here works for Cocos2d V3.

+(UIImage*) screenshotWithStartNode:(CCNode*)startNode
{
    [CCDirector sharedDirector].nextDeltaTimeZero = YES;

    CGSize viewSize = [[CCDirector sharedDirector] viewSize];
    CCRenderTexture* rtx =
    [CCRenderTexture renderTextureWithWidth:viewSize.width
                                     height:viewSize.height];
    [rtx begin];
    [startNode visit];
    [rtx end];

    return [rtx getUIImage];
}

Answer 2

I am not sure what the GitHub version does but this code will take a screenshot and I just tested it on iOS 6 and it works fine.

+(UIImage*) screenshotWithStartNode:(CCNode*)startNode
{
    [CCDirector sharedDirector].nextDeltaTimeZero = YES;

    CGSize winSize = [CCDirector sharedDirector].winSize;
    CCRenderTexture* rtx = 
    [CCRenderTexture renderTextureWithWidth:winSize.width 
                                 height:winSize.height];
    [rtx begin];
    [startNode visit];
    [rtx end];

    return [rtx getUIImage];
}

You can call it like this

CCScene *scene = [[CCDirector sharedDirector] runningScene];
CCNode *n = [scene.children objectAtIndex:0];
UIImage *img = [AppController screenshotWithStartNode:n];

Above 2 answers not worked in Cocos2d 3.2.1

Here is Solution for Cocos2d 3.2.1 +

-(UIImage*) takePresentScreenshot
{
    [CCDirector sharedDirector].nextDeltaTimeZero = YES;

    CGSize size = [[CCDirector sharedDirector] viewSize];
    CCRenderTexture *renderTxture = [CCRenderTexture renderTextureWithWidth:size.width
                                                                  height:size.height];
    [renderTxture begin];
    [[[CCDirector sharedDirector] runningScene] visit];
    [renderTxture end];

    return [renderTxture getUIImage];
}

UIImage* screenshot = [self takePresentScreenshot];

Answer 4

The top answer works for iPads (I have tested on iPads v1 thru 4).

It does NOT work for the actual device: iPhone5, iOS7.

However, it does work for simulators of such an iPhone 5!

That inconsistency is driving me crazy!
