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

``javascript
npm i nativescript-watchos-connector
`

Installation prior to NativeScript 7:

`javascript
npm i nativescript-watchos-connector@1.0.11
`

Usage

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

TypeScript
`javascript
import { WatchOSConnector } from 'nativescript-watchos-connector'

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

2. Import the nativescript-watchos-connector plugin:

TypeScript
`javascript
import { WatchOSConnector } from 'nativescript-watchos-connector'
`

3. Create an instance of the import in the constructor:

TypeScript
`javascript
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
`javascript
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
`javascript
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
`javascript
this.watchOSConnector.checkActivation()
`

convertInt(value)

Returns the value as a NSNumber with int

TypeScript
`javascript
this.watchOSConnector.convertInt(2319)
`

convertDouble(value)

Returns the value as a NSNumber with double

TypeScript
`javascript
this.watchOSConnector.convertDouble(42.957194)
`

convertFloat(value)

Returns the value as a NSNumber with float

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

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

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