## DYFBlurEffect

We can use `DYFBlurEffect` to quickly realize blurred image, and support `UIVisualEffectView` in iOS.

## Group (ID:614799921)

Using [CocoaPods](https://cocoapods.org):

```

pod 'DYFBlurEffect'

```

Or

```

pod 'DYFBlurEffect', '~> 2.1.1'

```

## Preview



  



## Usage

- Instantiation

```

// Lazy load

- (DYFBlurEffect *)blurEffect {

    if (!_blurEffect) {

        _blurEffect = [[DYFBlurEffect alloc] init];

    }

    return _blurEffect;

}

```

- Using CoreGraphics and vImage

    

```

// Uses a `DYFBlurEffectStyle` style.

self.imgView.image = [self.blurEffect blurryImage:image style:DYFBlurEffectLight];

// Tints with a color.

self.imgView.image = [self.blurEffect blurryImage:image tintColor:[UIColor colorWithRed:40/255.0 green:40/255.0 blue:40/255.0 alpha:1]];

```

```

/**

Blur out an image with an original image, a blur radius, tint with a color, a saturation delta factor and a mask image.

*/

- (UIImage *)blurryImage:(UIImage *)image blurRadius:(CGFloat)blurRadius tintColor:(UIColor *)tintColor saturationDeltaFactor:(CGFloat)saturationDeltaFactor maskImage:(UIImage *)maskImage;

```

- Using UIVisualEffectView (Available iOS 8.0 or later)

```

UIVisualEffectView *blurView = [self.blurEffect blurViewWithStyle:UIBlurEffectStyleLight];

blurView.frame = self.imgView.bounds;

//blurView.tag = 10;

//blurView.userInteractionEnabled = YES;

[self.view addSubview:blurView];

```

- Using CoreImage

```

 self.imgView.image = [self.blurEffect coreImage:image blurRadius:10];

```
