I’ve mentioned a few interesting projects inspired by the blurring effects added with iOS 7 specifically for adding blur effects into your apps such as this library for creating a dynamic blur effect and this library for creating a high-speed dynamic blur effect.
Here’s a UIImage category called UIImage-BlurredFrame that allows you to blur a specific area of a UIImage.
To use UIImage-BlurredFrame you simply specify a frame and apply to the image like in this example from the readme:
CGRect frame = CGRectMake(0, img.size.height - 200, img.size.width, img.size.height - 200);
img = [img applyLightBluredAtFrame:frame];
And this image from the readme shows the result of running this blurring code:
You can find UIImage-BlurredFrame on Github here.
UIImage-BlurredFrame was created from Apple’s WWDC 2013 Session 226.
A great library for applying a blur effect to your images easily.
