Dodo, a message bar for iOS

This is a UI widget for showing text messages in iOS apps. It is useful for showing short messages to the user, something like: "Message sent", "Note saved", "No Internet connection".

  • Dodo includes styles for success, info, warning and error type messages.
  • The bar can have buttons with custom tap handlers.
  • Bar styles can be customized.
  • You can provide custom animations for showing and hiding the bar or use one of the default animation presets.

At last the Dodo said, `EVERYBODY has won, and all must have prizes.'

Setup

There are two ways you can add Dodo to your project.

Setup with Carthage (iOS 8+)

Alternatively, add github "exchangegroup/Dodo" ~> 2.0 to your Cartfile and run carthage update.

Setup with CocoaPods (iOS 8+)

If you are using CocoaPods add this text to your Podfile and run pod install.

use_frameworks!
pod 'Dodo', '~> 2.0'

Setup in Swift 1.2 project

Use the previous version of the library.

Usage

Add import Dodo to your source code if you used Carthage or CocoaPods setup methods.

Dodo is an extension of UIView class. You can reach it by using using the dodo property in any instance of UIView or its subclass. It can be, for example, the view property of your view controller.

Show and hide message bar

view.dodo.success("Everybody has won and all must have prizes.")
view.dodo.info("Extinction is the rule. Survival is the exception.")
view.dodo.warning("This world is but a canvas to our imagination.")
view.dodo.error("The perception of beauty is a moral test.")

view.dodo.hide()

If you are showing the bar in the root view you may need to provide top or bottom layout guides. This will prevent the message bar from overlapping with the status or the tab bar.

view.dodo.topLayoutGuide = topLayoutGuide
view.dodo.bottomLayoutGuide = bottomLayoutGuide
view.dodo.success("Success is how high you bounce when you hit bottom.")

Styling

Set dodo.style property to style the message bar before it is shown. See the styling manual for the complete list of configuration options.

// Set the text color
view.dodo.style.label.color = UIColor.whiteColor()

// Set background color
view.dodo.style.bar.backgroundColor = DodoColor.fromHexString("#00000090")

// Close the bar after 3 seconds
view.dodo.style.bar.hideAfterDelaySeconds = 3

// Close the bar when it is tapped
view.dodo.style.bar.hideOnTap = true

// Show the bar at the bottom of the screen
view.dodo.style.bar.locationTop = false

Add buttons or icons

Set style.leftButton and style.rightButton properties to show buttons or icons.

// Use a built-in icon
view.dodo.style.leftButton.icon = .Close

// Supply your image
view.dodo.style.leftButton.image = UIImage(named: "CloseIcon")

// Change button's image color
view.dodo.style.leftButton.tintColor = DodoColor.fromHexString("#FFFFFF90")

// Do something on tap
view.dodo.style.leftButton.onTap = { /* Button tapped */ }

// Close the bar when the button is tapped
view.dodo.style.leftButton.hideOnTap = true

Customize animation

Configure the animation effect of the bar before it is shown. See the animation wiki pagefor more information.

// Use a built-in icon
view.dodo.style.leftButton.icon = .Close

// Supply your image
view.dodo.style.leftButton.image = UIImage(named: "CloseIcon")

// Change button's image color
view.dodo.style.leftButton.tintColor = DodoColor.fromHexString("#FFFFFF90")

// Do something on tap
view.dodo.style.leftButton.onTap = { /* Button tapped */ }

// Close the bar when the button is tapped
view.dodo.style.leftButton.hideOnTap = true

Unit testing

Sometimes it is useful to verify which messages were shown by your app in unit tests. It can be done by setting an instance of DodoMock class to view.dodo property.

See the unit testing manual for more details.
