nativescript-watchos-connector

This is a NativeScript plugin that uses Apple WatchConnectivity to pass and receive data to a companion WatchOS app.

Prerequisites / Requirements

Before using this plugin, make sure you have followed the NativeScript blog post on Developing a watchOS Extension For Your NativeScript App and iOS WatchOS Applications.

Installation NativeScript 7

npm i nativescript-watchos-connector

Installation prior to NativeScript 7:

npm i nativescript-watchos-connector@1.0.11

Usage

NativeScript Angular

For this plugin to work you must first add the nativescript-watchos-connector as a provider in your app.module.ts:

TypeScript

import  {  WatchOSConnector  }  from  'nativescript-watchos-connector'

@NgModule({
	bootstrap: [AppComponent],
	imports: [],
	providers: [ WatchOSConnector ],
	declarations: [ AppComponent ],
	schemas: [ NO_ERRORS_SCHEMA ]
})

Import the nativescript-watchos-connector plugin:

TypeScript

import  {  WatchOSConnector  }  from  'nativescript-watchos-connector'

Create an instance of the import in the constructor:

TypeScript

constructor(
	private _watchOSConnector: WatchOSConnector
) {}

Plugin Overview

This is a list of all currently available functions and a brief description of their usage within this plugin.

Function	Description
`createWCSession()`	Creates a WCSession
`watchOSChecker()`	Checks if the user is on iOS, has an Apple Watch paired and the WatchOS app is installed
`checkActivation()`	Checks if the WCSession is active (if not, session will be activated)
`convertInt(value)`	Return value as Obj-C int
`convertDouble(value)`	Return value as Obj-C double
`convertFloat(value)`	Return value as Obj-C float
`sendObjectToWatch('objectKey', object)`	Send the data to the companion WatchOS App using ApplicationContext

createWCSession()

createWCSession checks if the device can support a WCSession, if so a WCSession will be created.

TypeScript

this.watchOSConnector.createWCSession()

watchOSChecker()

Use watchOSChecker instead of isIOS when working with passing data to the Apple Watch. This checks if the user is on iOS, has an Apple Watch paired and the WatchOS app is installed (returns boolean)

TypeScript

if (this.watchOSConnector.watchOSChecker()) {
// Only run if WatchOS app is avalaible
}

checkActivation()

Checks if the WCSession is active, if not this will activate the current session. This is called in sendObject() to ensure there is an active session.

TypeScript

this.watchOSConnector.checkActivation()

convertInt(value)

Returns the value as a NSNumber with int

TypeScript

this.watchOSConnector.convertInt(2319)

convertDouble(value)

Returns the value as a NSNumber with double

TypeScript

this.watchOSConnector.convertDouble(42.957194)

convertFloat(value)

Returns the value as a NSNumber with float

TypeScript

this.watchOSConnector.convertFloat(882.152)

sendObjectToWatch(objectKey, object)

Sends the data to the companion WatchOS app using updateApplicationContext. You need to pass in a key for the object and an object of Objective-C valid values.

TypeScript

let intValue =  this.watchOSConnector.convertInt(4)
let doubleValue =  this.watchOSConnector.convertDouble(45.1)

let numberObject =  {
	convertedInt: intValue,
	convertedDouble: doubleValue
}

this.watchOSConnector.sendObject('numberObjectKey', numberObject)

v2.0.0 Release
