GradientLoadingBar

An animated gradient loading bar. Inspired by iOS Style Gradient Progress Bar with Pure CSS/CSS3.

Integration

GradientLoadingBar can be added to your project using CocoaPods by adding the following line to your Podfile:

pod 'GradientLoadingBar', '~> 1.0'

How to use

To get started 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, durations and gradientColors:

let loadingBar = GradientLoadingBar(
    height: 1.0,
    durations: Durations(fadeIn: 1.0, fadeOut: 2.0, progress: 3.0)
    gradientColors: [
        UIColor(hexString:"#4cd964").cgColor,
        UIColor(hexString:"#ff2d55").cgColor
    ]
)

For custom colors you have to pass an array with CGColor values. For creating those colors you can use all initializers for UIColor mentioned here: UIColor+Initializers.swift

Custom shared instance

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: 3.0,
    durations: Durations(fadeIn: 1.0, fadeOut: 2.0, progress: 3.00),
    gradientColors: [
        UIColor(hexString:"#4cd964").cgColor,
        UIColor(hexString:"#ff2d55").cgColor
    ]
).saveInstance()

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