Usage
Objective-C
In order to integrate the library into Object-C project, please follow the instructions from this doc.
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)
Enable TapThrough
By default, tapping a showcase's target does not perform it's predefined action. This can be overridden.
// UIButton
showcase.setTargetView(button: button, tapThrough: true)
// UIBarButtonItem
showcase.setTargetView(barButtonItem: barItem, tapThrough: true)
// UITabBar item
showcase.setTargetView(tabBar: tabBar, itemIndex: 0, tapThrough: true)
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.")
}
}
Dismiss showcase programmatically
showcase.completeShowcase(animated: true, didTapTarget: false)
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.isTapRecognizerForTargetView = true
Customize UI properties
You can define your own styles based on your app.
// Background
showcase.backgroundAlpha = 0.9
showcase.backgroundPromptColor = UIColor.blue
showcase.backgroundPromptColorAlpha = 0.96
showcase.backgroundViewType = .full // default is .circle
showcase.backgroundRadius = 300
// Target
showcase.targetTintColor = UIColor.blue
showcase.targetHolderRadius = 44
showcase.targetHolderColor = UIColor.white
// Text
showcase.primaryTextColor = UIColor.white
showcase.secondaryTextColor = UIColor.white
showcase.primaryTextSize = 20
showcase.secondaryTextSize = 15
showcase.primaryTextFont = UIFont.boldSystemFont(ofSize: primaryTextSize)
showcase.secondaryTextFont = UIFont.systemFont(ofSize: secondaryTextSize)
//Alignment
showcase.primaryTextAlignment = .left
showcase.secondaryTextAlignment = .left
// Animation
showcase.aniComeInDuration = 0.5 // unit: second
showcase.aniGoOutDuration = 0.5 // unit: second
showcase.aniRippleScale = 1.5
showcase.aniRippleColor = UIColor.white
showcase.aniRippleAlpha = 0.2
//...
Sequence items
You can define showcase items and create sequence.
If you set key param sequence visible just one time or key is empty will always show be repeated
Always appear
let sequence = MaterialShowcaseSequence()
let showcase2 = MaterialShowcase()
let showcase3 = MaterialShowcase()
let showcase1 = MaterialShowcase()
showcase1.delegate = self
showcase2.delegate = self
showcase3.delegate = self
sequence.temp(showcase1).temp(showcase2).temp(showcase3).start()
Will appear once so we have key
let sequence = MaterialShowcaseSequence()
let showcase2 = MaterialShowcase()
let showcase3 = MaterialShowcase()
let showcase1 = MaterialShowcase()
showcase1.delegate = self
showcase2.delegate = self
showcase3.delegate = self
//Once the key value changes , it will appear once
sequence.temp(showcase1).temp(showcase2).temp(showcase3).setKey(key: "temp").start()
Must extends MaterialShowCaseDelegate and This code into showCaseDidDismiss function
extension ViewController: MaterialShowcaseDelegate {
func showCaseDidDismiss(showcase: MaterialShowcase, didTapTarget: Bool) {
sequence.showCaseWillDismis()
}
}
