Usage

Android

import {TNSCoachMarks, TNSCoachMark} from 'nativescript-coachmarks';

// assuming page is defined
let AndroidButton = page.getViewById('my-button')
let AndroidLabel = page.getViewById('my-label');
let cm = new TNSCoachMarks();
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 TNSCoachMark({
    caption: '1. My Button.',
    view: AndroidButton
  }),
  new TNSCoachMark({
    caption: '2. My Label.',
    view: AndroidLabel
  })
];

cm.start(marks);

Simple

Use static methods to show coachmarks.

import {TNSCoachMarks, TNSCoachMark} from 'nativescript-coachmarks';

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

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

TNSCoachMarks.start(marks);

Advanced

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

import {TNSCoachMarks, TNSCoachMark, ICoachMarkOptions} from '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 TNSCoachMarks instance
let coachMarksInstance = new TNSCoachMarks();

// 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 TNSCoachMark({
    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: TNSCoachMark.SHAPES.DEFAULT,
    labelPosition: TNSCoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: TNSCoachMark.LABEL_ALIGNMENTS.LEFT,
    showArrow: true
  }),
  new TNSCoachMark({
    position: CGRectMake(
      iOSLabel.frame.origin.x, 
      iOSLabel.frame.origin.y + 64, 
      iOSLabel.frame.size.width, 
      iOSLabel.frame.size.height
    ),
    caption: '2. My Label.',
    shape: TNSCoachMark.SHAPES.DEFAULT,
    labelPosition: TNSCoachMark.LABEL_POSITIONS.BOTTOM,
    labelAlignment: TNSCoachMark.LABEL_ALIGNMENTS.CENTER,
    showArrow: true
  })
];

TNSCoachMarks.start(marks, options, coachMarksInstance);

Why the TNS prefixed name?

TNS stands for Telerik NativeScript

iOS uses classes prefixed with NS (stemming from the NeXTSTEP days of old): https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/

To avoid confusion with iOS native classes, TNS is used instead.
