Material Showcase for iOS

An elegant and beautiful tap showcase view for iOS apps based on Material Design Guidelines.

Requirement

• iOS 8.0+
• Swift 3.0+

Installation

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate MaterialShowcase into your Xcode project using Carthage, specify it in your Cartfile:

github "aromajoin/material-showcase-ios" ~> 0.6.1

Run carthage update to build the framework and drag the built MaterialShowcase.framework into your Xcode project.

CocoaPods

You can install it by using CocoaPods. Please add the following line to your Podfile.

pod 'MaterialShowcase'

Usage

Objective-C

Please, read this doc and follow the instructions.

Basic

  let showcase = MaterialShowcase()
  showcase.setTargetView(view: button) // always required to set targetView
  showcase.primaryText = "Action 1"
  showcase.secondaryText = "Click here to go into details"
  showcase.show(completion: {
    // You can save showcase state here
    // Later you can check and do not show it again
  })

Note: showcase.show() should be called after your views are placed correctly, for example inside UIViewController's viewWillAppear() or viewDidAppear() function. You SHOULD NOT call it inside viewDidLoad() because views have not laid down correctly yet, showcase can not calculate these views positions and it results in unexpected errors.

Supported target views

There are several target view supported.

  // Any UIView
  showcase.setTargetView(view: view)
  // UIBarButtonItem
  showcase.setTargetView(barButtonItem: barItem)
  // UITabBar item
  showcase.setTargetView(tabBar: tabBar, itemIndex: 0)
  // UItableViewCell
  showcase.setTargetView(tableView: tableView, section: 0, row: 0)

Handle showcase status

  // Right after showing.
  showcase.show(completion: {
    // You can save showcase state here
  })
  
  // To handle other behaviors when showcase is dismissing, delegate should be declared.
  showcase.delegate = self
  
  extension ViewController: MaterialShowcaseDelegate {
    func showCaseWillDismiss(showcase: MaterialShowcase, didTapTarget: Bool) {
      print("Showcase \(showcase.primaryText) will dismiss.")
    }
    func showCaseDidDismiss(showcase: MaterialShowcase, didTapTarget: Bool) {
      print("Showcase \(showcase.primaryText) dimissed.")
    }
  }

Support both LTR and RTL text alignment

In default, text aligment is set to be left-to-right. If you want to show text in right-to-left direction. Please define following.

showcase.primaryTextAlignment = .right
showcase.secondaryTextAlignment = .right

Dismiss showcase only if users click to target view

In default, showcase will be dismissed when users click to any place in whole showcase view. If you want to dismiss showcase only when users click to target view correctly, please set the following property.

showcase.isTapRecognizerForTagretView = true

  // Background
  showcase.backgroundPromptColor = UIColor.blue
  showcase.backgroundPromptColorAlpha = 0.96
  showcase.backgroundViewType = .full // default is .circle
  // Target
  showcase.targetTintColor = UIColor.blue
  showcase.targetHolderRadius = 44

  showcase.secondaryTextFont = UIFont.systemFont(ofSize: secondaryTextSize)
  //Alignment
  showcase.primaryTextAlignment = .left
  showcase.secondaryTextAlignment = .left
  // Animation
  showcase.aniComeInDuration = 0.5 // unit: second
