LBBlurredImage is an UIImageView category that permit to set an image and make this blurred.

Here are an example of what you can achieve:

• Just grab the two file named UIImageView+LBBlurredImage.h & UIImageView+LBBlurredImage.m in the Additions group into your project and link with CoreImage.framework .
• #import "UIImageView+LBBlurredImage.h" where you need it.

[self.imageView setImageToBlur:[UIImage imageNamed:@"example"]
 blurRadius:kLBBlurredImageDefaultBlurRadius
 completionBlock:^(NSError *error){
 NSLog(@"The blurred image has been setted");
 }];

The generation of the blurred image is made on a background thread, for this reason a completion block is provided. The completionBlock is dispatched on the main thread when the image was generated and set to the UIImageView.
