## Requirements

* iOS 8.0 +
* Swift 3.0 +

## Install

### Carthage

Add following code to your `Cartfile`, and run `carthage update`:

```ruby
github "DanisFabric/RainbowNavigation"
```

## Usage

### Change backgroundColor of `UINavigationBar`

Make `UINavigationBar` transparent

```
navigationBar.df_setBackgroundColor(UIColor.clearColor())
```
Restore the default values

```
navigationBar.df_reset()
```
You can add a mask for statusBar:

```Swift
navigationBar.df_setStatusBarMaskColor(UIColor.blackColor().colorWithAlphaComponent(0.1))
```

### Support `UINavigationController` Operations

1. wire the `UINavigationController` to `RainbowNavigation`

```Swift
lazy var rainbowNavigation = RainbowNavigation()
   override func viewDidLoad() {
        super.viewDidLoad()
        if let navController = self.navigationController {
            rainbowNavigation.wireTo(navigationController: navController)
        }
    }
```

2. Your viewController need to confirm `RainbowColorSource` protocol, and offer the color which navigationBar will change into.

```Swift
@objc public protocol RainbowColorSource {
    optional func navigationBarInColor() -> UIColor    
    optional func navigationBarOutColor() -> UIColor   
}
```
