Get image from uiview

Question

I want to perform animation compression on UITableVIew. I experimented a bit and found out that the animation is much faster when I reduce the UIImageView with an image of the current state of the table, instead of reducing the presentation of the table.

I captured the image in the method in my main view manager before the animation:

UIGraphicsBeginImageContext(mainTableView.bounds.size);

[resizeContainer.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

Works like a charm, at least almost. In very rare cases, I get strange graphical crashes where UIImage begins to overlap the toolbar below it.

I just want to make sure I get the image correctly. I understand that you need to understand GraphicContexts.

In short, is my code correct?

thanks
