Remove Top View From Hierarchy When Saving Screenshot - iphone

Question

I am using a method to take a UIImage screenshot programatically which works very nicely. What I want to do now is remove the top most UIView from being included in the screenshot BUT not remove it from the actual view on screen so simply setting topView.hidden = YES won't do. I am using this method to save the screenshot:
- (UIImage*)screenshot
{
CGSize imageSize = [[UIScreen mainScreen] bounds].size;
if (NULL != UIGraphicsBeginImageContextWithOptions)
UIGraphicsBeginImageContextWithOptions(imageSize, NO, 0);
else
UIGraphicsBeginImageContext(imageSize);
CGContextRef context = UIGraphicsGetCurrentContext();
// Iterate over every window from back to front
for (UIWindow *window in [[UIApplication sharedApplication] windows])
{
if (![window respondsToSelector:#selector(screen)] || [window screen] == [UIScreen mainScreen])
{
// -renderInContext: renders in the coordinate space of the layer,
// so we must first apply the layer's geometry to the graphics context
CGContextSaveGState(context);
// Center the context around the window's anchor point
CGContextTranslateCTM(context, [window center].x, [window center].y);
// Apply the window's transform about the anchor point
CGContextConcatCTM(context, [window transform]);
// Offset by the portion of the bounds left of and above the anchor point
CGContextTranslateCTM(context,
-[window bounds].size.width * [[window layer] anchorPoint].x,
-[window bounds].size.height * [[window layer] anchorPoint].y);
// Render the layer hierarchy to the current context
[[window layer] renderInContext:context];
// Restore the context
CGContextRestoreGState(context);
}
}
// Retrieve the screenshot image
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
My first thought was to remove the sublayer from the superlayer doing this:
NSArray *sublayers = [[window layer] sublayers];
[[window layer] replaceSublayer:[sublayers objectAtIndex:[sublayers count] - 1] with:nil];
but I found that the sublayers array is only 1 object. How could I remove the top view from the screenshot?

For example you have View1 on your view hierarchy and you don't want to take screenshot of View1 then you can do View1.hiden= TRUE; before screenshot and you can do View1.hiden= FALSE; after screenshot.
May be this will help you.
