BubbleShowCase is an elegant and easy to use framework that provides developers with a user-friendly buble-like view you can display to help your users understand your App features, improve the use of some functionality or display your App onboarding. It consists of a translucent view that obscures the screen, a bubble that displays the message for your user and the targeted view itself.

• iOS 9.0+
• Swift 4.0+

pod 'BubbleShowCase'

To integrate BubbleShowCase into your Xcode project using Carthage, create a Cartfile and add:

github "ECLaboratorio/BubbleShowCase-iOS"

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

If you don't have know what HomeBrew is, check their site for installation instructions.

It's pretty simple to show-case a feature in your App by using BubbleShowCase framework. All you have to do is initializing a show case by using one of its constructors, customizing it the way you want and calling its show method:

let showCase: BubbleShowCase! = BubbleShowCase(target: myBarButton)
showCase.titleText = "You know what?"
showCase.descriptionText = "You can do amazing things if you tap on this navbar button"
showCase.image = UIImage(named: "show-case-bar-button")
showCase.show()		// Simple as that

Note: You should call show when the target is loaded, set and positioned in the screen.

• UIView
• UITableView
• UICollectionView
• UIBarButtonItem
• UITabBarItem

BubbleShowCase offers several constructors depending on the targets. Use the specific constructor in case of UITableViewCell or UICollectionViewCell:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
	if indexPath.row == Constants.IndexPathForShowCase {
		let showCase = BubbleShowCase(cell: cell, target: nil, arrowDirection: .down)
		showCase.titleText = "Am I not in the screen?"
		showCase.descriptionText = "I'll stop the scroll and make sure the cell displays"
		showCase.shadowColor = UIColor.green
		
		showCase.show()
	}
}

Customize your show cases according to your App style:

showCase.color = UIColor.yellow
showCase.textColor = UIColor.black
showCase.shadowColor = UIColor.black
showCase.crossColor = UIColor.red
showCase.arrowDirection = .up
showCase.titleText = "My first show case"
showCase.descriptionText = "I hope you enjoy it"
showCase.image = UIImage(named: "my-show-case-image")
showCase.delegate = self
showCase.titleFont = UIFont(name: "Roboto-Bold", size: 14)!
showCase.descriptionFont = UIFont(name: "Roboto-Regular", size: 13)!

showCase.showAnimationDuration = 0.2
showCase.dismissAnimationDuration = 0.2
showCase.flickerAnimationDuration = 0.2

// Use this to force your users to tap or perform any other gesture over the target view
showCase.isCrossDismissable = false	

Do you need to show-case several features one after another? That's easy, you just have to call concat(bubbleShowCase:) or show(after:). The former concatenates the argument as the next show case to show whereas the latter displays the show case after the argument:

let firstShowCase = BubbleShowCase(...)
let secondShowCase = BubbleShowCase(...)

firstShowCase.concat(bubbleShowCase: secondShowCase)	// secondShowCase.show(after: firstShowCase)

Conform to BubbleShowCaseDelegate to be aware of the show case status in the screen or to be notified of common gestures recognized over the target:

let showCase = BubbleShowCase(...)
showCase.delegate = self

...
...

func bubbleShowCase(_ bubbleShowCase: BubbleShowCase, didTap target: UIView!, gestureRecognizer: UITapGestureRecognizer) {
	print("Target was tapped!")
}

Note: In order to show-case a UIBarButton, this must be constructed by means of a custom view:

let myBarButton = UIBarButtonItem(customView: myCustomView)
let showCase: BubbleShowCase! = BubbleShowCase(target: myBarButton)
...
showCase.show()
