How do I blur (ios7 style) a section of an image in a UITableViewCell?
- by George McKibbin
I've got a UIImageView that takes up the whole cell and shows an image. I'd like to blur the bottom third of the view in the iOS7 style (we're targeting iOS7). There will be a label over the blurred part.
The issue seems to be that I can't "screenshot" the UIImageView right as I am setting up the cell in tableView:cellForRowAtIndexPath: as it hasn't loaded yet. Although i've even tried setting up a timer for a 0.1 second delay and that also doesn't work.
I've tried the stuff on http://damir.me/posts/ios7-blurring-techniques
I've tried https://github.com/justinmfischer/7blur
I'd like to use the new screenshotting API drawViewHierarchyInRect:afterScreenUpdates:
I'd also like to use apple's sample code UIImage+ImageEffects
The only thing that has worked so far has been to just put a UIToolbar in but the performance is really slow. I don't need dynamic updates.
I've managed to get the following effect a few times but it has just tinted the view and hasn't actually blurred anything so I'm a bit confused.
