Jump to the code:

Now open your Xcode project and import two files required to create blur effect in the file where you need to add blur effect.


#import "UIImage+ImageEffects.h"
#import "UIImage+UIImage_ScreenShot_.h"

Below is the code that creates the nice blur effect

  UIImage *imageScreenShot = [UIImage screenshot];
    UIImage *blurred = [imageScreenShot applyLightEffect];
    UIImageView *blurrImageView = [[UIImageView alloc]initWithFrame:[UIScreen mainScreen].bounds];
    blurrImageView.image = blurred;
    [[UIApplication sharedApplication].delegate.window addSubview:blurrImageView];

In above code first we capture screenshot of our view. Then we applied the blur effect to the captured screenshot image. Finally we present the blurred image to our UIImageView and add it to our app window as subview.
