# MotionBlur

`MotionBlur` allows you to add motion blur effect to your animations (currently only position's change). See the [accompanying blog post](http://holko.pl/2014/07/21/motion-blur/) to learn how it's implemented.

*Note how the text and icons on the menu get blurred when it slides in and out.*

## Usage

First, import it with:

```obj-c

#import "UIView+MotionBlur.h"

```

then use it with:

```obj-c

[yourView enableBlurWithAngle:M_PI_2 completion:^{

    [UIView animateWithDuration:0.5

                          delay:0

         usingSpringWithDamping:0.8

          initialSpringVelocity:0.3

                        options:UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionBeginFromCurrentState

                     animations:^{

        CGRect f = yourView.frame;

        f.origin = CGPointMake(0, 300);

        yourView.frame = f;

    } completion:^(BOOL finished) {

        [yourView disableBlur];

    }];

}];

```

Snapshot and blur are computed before the animation, that's why the API is asynchronous. You should also see the example project and read comments in the header file: `Classes/UIView+MotionBlur.h`.

## Demo
