Installation

Copy file

This code must be used with deploy target 6.0+ and under ARC. If your code doesn't use ARC you can mark this source with the compiler flag -fobjc-arc

• Just grab the two file named UIImageView+LBBlurredImage.{h,m} and UIImageImage+ImageEffects.{h,m} in the Additions group into your project and link with Accelerate.framework .
• #import "UIImageView+LBBlurredImage.h" where you need it.

Use

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

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 has been generated and set to the UIImageView.

The code is provided with an example project if you want to see the class in actions.
