Snackbar

A handy Swift toolbar-like widget for quickly displaying status updates and errors at the bottom of the screen. See the Android snackbar, which this is named after.

What can Snackbar do?

Asynchronously displays...

a status title and message with animation
an error title and message with animation as well as a customizable retry action
a success / confirmation title and message with animation, and then auto-hide

Installation

To install via Cocoapods

pod 'Snackbar', '~> 0.1.0'

Usage

let snackbar = Snackbar()
view.addSubview(snackbar)

// Start some long-running task...
snackbar.updateWithStatus("Syncing Data", message: "This may take a moment...")

// If/when that task finishes...
snackbar.completeWithStatus("Syncing Complete", message: "Your data seems to all be here.")

// If the tasks fails, you can handle the error like so...
snackbar.updateWithError("Error",
  message: error.localizedDescription,
  actionOptions: (buttonTitle: "RETRY", statusTitle: "Retrying", statusMessage: "Sit tight...", onSelect: { Void in
     // fetchData()
  })
)

Customizing the appearance

Snackbar can be initialized with a customized SnackbarConfiguration instance. The following attributes can be customized via the SnackbarConfiguration.

backgroundColor
foregroundColor
headerFont - First line of text
subHeaderFont - Second line of text
presentationAnimationDuration
dismissalAnimationDelay - Length of time that status updates will remain on screen before dismissing. Default is 2 seconds.

Initialize the configuration and pass it as the configuration parameter when initializing the Snackbar.

let configuration = SnackbarConfiguration(
  backgroundColor: UIColor.whiteColor(),
  foregroundColor: ...
)
let customizedSnackbar = Snackbar(configuration: configuration)
