### Integration
GradientLoadingBar can be added to your project using [CocoaPods](https://cocoapods.org/) by adding the following line to your Podfile:
```
pod 'GradientLoadingBar', '~> 1.0'
```
### How to use
First you need to import __"GradientLoadingBar"__. After that you can use __"GradientLoadingBar.sharedInstance()"__ to retrieve an instance to the loading bar. To show it, simply call the __"show()"__ method and after you're done call __"hide()"__.
```
// Show loading bar
GradientLoadingBar.sharedInstance().show()

// Do e.g. server calls etc.

// Hide loading bar
GradientLoadingBar.sharedInstance().hide()
```

### Configuration
You can overwrite the default configuration by calling the initializers with the optional params __"height"__ and __"durations"__:
```
let loadingBar = GradientLoadingBar(
    height: 1.0,
    durations: Durations(fadeIn: 1.0, fadeOut: 2.0, progress: 3.00)
)
```

If you don't want to save the instance on a variable and use the singleton instead, you can use the __"saveInstance()"__ method. Add the following code to your app delegate __"didFinishLaunchingWithOptions"__ method:
```
GradientLoadingBar(
    height: 1.0,
    durations: Durations(fadeIn: 1.0, fadeOut: 2.0, progress: 3.00)
).saveInstance()
```

After that you can use __"GradientLoadingBar.sharedInstance()"__ as mentioned above.
