NativeScript plugin to display user coach marks utilizing shape cutouts over an existing UI. This approach leverages your actual UI as part of the onboarding process for your user.

Based on MPCoachMarks.

You can view screenshots here.

Install

npm install @nstudio/nativescript-coachmarks --save

Usage

Android

import { CoachMarks, CoachMark } from '@nstudio/nativescript-coachmarks';

// assuming page is defined
let AndroidButton = page.getViewById('my-button')
let AndroidLabel = page.getViewById('my-label');
let cm = new CoachMarks();
cm.initEvents(); //If you want events

cm.events.on('click', (eventData) => {
  // clicked on item at step index: eventData.data.index
});
cm.events.on('cleanup', (eventData) => {
  // clean up any instances in your implementation
});
cm.events.on('navigate', (eventData) => {
  // navigated to index
});

let marks = [
  new CoachMark({
    caption: '1. My Button.',
    view: AndroidButton
  }),
  new CoachMark({
    caption: '2. My Label.',
    view: AndroidLabel
  })
];

cm.start(marks);

Simple

Use static methods to show coachmarks.

import { CoachMarks, CoachMark } from '@nstudio/nativescript-coachmarks';

// assuming page is defined
let iOSButton = page.getViewById('my-button').ios;
let iOSLabel = page.getViewById('my-label').ios;

let marks = [
  new CoachMark({
    position: CGRectMake(
      iOSButton.frame.origin.x - 5,
      iOSButton.frame.origin.y + 20,
      iOSButton.frame.size.width + 10,
      iOSButton.frame.size.height
    ),
    caption: '1. My Button.',
    shape: CoachMark.SHAPES.DEFAULT,
    labelPosition: CoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: CoachMark.LABEL_ALIGNMENTS.LEFT,
    showArrow: true
  }),
  new CoachMark({
    position: CGRectMake(
      iOSLabel.frame.origin.x, 
      iOSLabel.frame.origin.y + 64, 
      iOSLabel.frame.size.width, 
      iOSLabel.frame.size.height
    ),
    caption: '2. My Label.',
    shape: CoachMark.SHAPES.DEFAULT,
    labelPosition: CoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: CoachMark.LABEL_ALIGNMENTS.CENTER,
    showArrow: true
  })
];

CoachMarks.start(marks);

Advanced

Configure advanced options by creating an instance to listen to events and further customize coachmarks.

import { CoachMarks, CoachMark, ICoachMarkOptions } from '@nstudio/nativescript-coachmarks';

// define custom options
let options: ICoachMarkOptions = {
  continueLabelText: 'Tap Screen for Next Tip',
  skipButtonText: 'Exit',
  lblSpacing: 15,
  maskColor: UIColor.colorWithRedGreenBlueAlpha(0.30, 0.46, 0.89, .9)
};

// create a CoachMarks instance
let coachMarksInstance = new CoachMarks();

// initialize events
coachMarksInstance.initEvents();

// wire up events

// fired each time user taps screen and advances to next step (including the first step display)
coachMarksInstance.events.on('navigate', (eventData) => {
  console.log(`navigated to index: ${eventData.data.index}`);

  // customize 'continue' label or 'skip' button
  // their style can be changed upon each step or only once on first step
  // first, grab the coachmarks instance
  let instance = eventData.data.instance;

  // wanna change the arrow image for each step?
  instance.arrowImage.image = UIImage.imageNamed('custom-arrow.png');

  if (instance.lblContinue) {
    // customize continue button
    // only available when the first step fires (disappears after first tap)
    let labelContinue = instance.lblContinue.frame;
    instance.lblContinue.frame = CGRectMake(labelContinue.origin.x, labelContinue.origin.y - 20, labelContinue.size.width, labelContinue.size.height + 20);
    instance.lblContinue.backgroundColor = new Color('#FFE108').ios; 
    
    // custom caption color
    instance.lblCaption.textColor = new Color('#FFE108').ios;

    // customize skip button
    let btnSkip = instance.btnSkipCoach.frame;
    instance.btnSkipCoach.frame = CGRectMake(btnSkip.origin.x, btnSkip.origin.y - 20, btnSkip.size.width, btnSkip.size.height + 20);
  }    
});
coachMarksInstance.events.on('click', (eventData) => {
  // clicked on item at step index: eventData.data.index
});
coachMarksInstance.events.on('cleanup', (eventData) => {
  // clean up any instances in your implementation
});

// define your marks

// assuming page is defined
let iOSButton = page.getViewById('my-button').ios;
let iOSLabel = page.getViewById('my-label').ios;

let marks = [
  new CoachMark({
    position: CGRectMake(
      iOSButton.frame.origin.x - 5,
      iOSButton.frame.origin.y + 20,
      iOSButton.frame.size.width + 10,
      iOSButton.frame.size.height
    ),
    caption: '1. My Button.',
    shape: CoachMark.SHAPES.DEFAULT,
    labelPosition: CoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: CoachMark.LABEL_ALIGNMENTS.LEFT,
    showArrow: true
  }),
  new CoachMark({
    position: CGRectMake(
      iOSLabel.frame.origin.x, 
      iOSLabel.frame.origin.y + 64, 
      iOSLabel.frame.size.width, 
      iOSLabel.frame.size.height
    ),
    caption: '2. My Label.',
    shape: CoachMark.SHAPES.DEFAULT,
    labelPosition: CoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: CoachMark.LABEL_ALIGNMENTS.CENTER,
    showArrow: true
  })
];

CoachMarks.start(marks, options, coachMarksInstance);
