## Usage

BusyNavigationBar is available through [CocoaPods](http://cocoapods.org). To install

it, simply add the following lines to your Podfile:

```ruby

use_frameworks!

pod "BusyNavigationBar"

```

Or add the following lines to your Cartfile:

```bash

github "gmertk/BusyNavigationBar" "master"

```

	

After installation is done, you can use the new methods of your navigation bar; `start(_ options: BusyNavigationBarOptions)` and `stop()`.

## Properties

```swift

var options = BusyNavigationBarOptions()

/**

    Animation type

    - Stripes: Sliding stripes as seen in Periscope app.

    - Bars: Bars going up and down like a wave.

    - CustomLayer(() -> CALayer): Your layer to be inserted in navigation bar. In this case, properties other than `transparentMaskEnabled` and `alpha` will not be used. 

*/

options.animationType = .Stripes

/// Color of the shapes. Defaults to gray.

options.color = UIColor.grayColor()

/// Alpha of the animation layer. Remember that there is also an additional (constant) gradient mask over the animation layer. Defaults to 0.5.

options.alpha = 0.5

/// Width of the bar. Defaults to 20.

options.barWidth = 20

/// Gap between bars. Defaults to 30.

options.gapWidth = 30

/// Speed of the animation. 1 corresponds to 0.5 sec. Defaults to 1.

options.speed = 1

/// Flag for enabling the transparent masking layer over the animation layer.

options.transparentMaskEnabled = true

// Start animation

self.navigationController?.navigationBar.start(options)

// Stop animation

self.navigationController?.navigationBar.stop()

```
