Get a image from a uiview
- by Monobono
Hi
I want to perform a shrink animation on a UITableVIew. I experimented a bit and found out that the animation runs much faster when I shrink a UIImageView with an image of the current state of the tableview instead of shrinking the table view itself.
I grabbed the image in a method in my main viewcontroller prior to the animation:
UIGraphicsBeginImageContext(mainTableView.bounds.size);
[resizeContainer.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
Works like a charm, at least almost. On very rare occasions I get weird graphic glitches, where the UIImage starts to overlap a toolbar that lies underneath it.
I just want to make sure that I am getting the image in the right way. I am laking the necessary understand of GraphicContexts to be sure about it.
To cut a long story short, is my code correct?
Thx
