NativeScript Calendar Plugin

The Calendar plugin allows you to manipulate events in the user's native Calendar. You can find, create and delete events in either the default or a custom calendar.

If you're looking for an awesome in-app UI for the native calendar, then check this out.

Installation

From the command prompt go to your app's root folder and execute:

NativeScript 7

tns plugin add nativescript-calendar

NativeScript 6

tns plugin add nativescript-calendar@2.2.1

iOS runtime permission reason

You probably have seen a permission popup like this before (this plugin will trigger one as well, automatically):

iOS 10+ requires not only this popup, but also a reason. In this case it's "Custom message from App_Resources".

You can provide your own reason for accessing the calendar by adding something like this to app/App_Resources/ios/Info.plist:

<key>NSCalendarsUsageDescription</key>
  <string>My reason justifying fooling around with your calendar</string>

To not crash your app in case you forgot to provide the reason this plugin adds an empty reason to the .plist during build. This value gets overridden by anything you specified yourself. You're welcome.

TypeScript Usage

Of course you can use this plugin with TypeScript, just import the plugin and usethe functions summed up below like this:

import * as Calendar from "nativescript-calendar";

// example for listCalendars:
Calendar.listCalendars().then(/* .. */);

Usage

If you want a quickstart, clone our demo app.

createEvent

var Calendar = require("nativescript-calendar");

  // Only the `title`, `startDate` and `endDate` are mandatory, so this would suffice:
  var options = {
    title: 'Get groceries',
    // Make sure these are valid JavaScript Date objects.
    // In this case we schedule an Event for now + 1 hour, lasting 1 hour.
    startDate: new Date(new Date().getTime() + (60*60*1000)),
    endDate: new Date(new Date().getTime() + (2*60*60*1000))
  };

  // You can however add lots of properties to enrich the Event:
  options.location = 'The shop';
  options.notes = 'This event has reminders';

  // iOS has a separate 'url' field, but on Android the plugin appends this to the 'notes' field.
  options.url = 'http://my.shoppinglist.com';

  // You can also override the default reminder(s) of the Calendar (in minutes):
  options.reminders = {
    first: 30,
    second: 10
  };

  // You can make this Event recurring (this one repeats every other day for 10 days):
  options.recurrence = {
    frequency: "daily", // daily | weekly | monthly | yearly
    interval: 2, // once every 2 days
    endDate: new Date(new Date().getTime() + (10*24*60*60*1000)) // 10 days
  };

  // Want to use a custom calendar for your app? Pass in the 'name'.
  // If the name doesn't yet exist the plugin will create it for you.
  options.calendar = {
    name: "NativeScript Cal",
    // the color, in this case red
    color: "#FF0000",
    // Can be used on Android to group the calendars. Examples: Your app name, or an emailaddress
    accountName: "My App Name"
  };

  Calendar.createEvent(options).then(
      function(createdId) {
        console.log("Created Event with ID: " + createdId);
      },
      function(error) {
        console.log("Error creating an Event: " + error);
      }
  );

If you want an 'all day event', make sure you set the dates to midnight like this:

var d = new Date();
  d.setHours(0);
  d.setMinutes(0);
  d.setSeconds(0);

  // this will create an 'all day event' for tomorrow
  var startDate = new Date(d.getTime() + (24*60*60*1000));
  var endDate = new Date(d.getTime() + (2*24*60*60*1000));
  // .. now use these properties in the options object

findEvents

var options = {
    // when searching, dates are mandatory - the event must be within this interval
    startDate: new Date(new Date().getTime() - (50*24*60*60*1000)),
    endDate: new Date(new Date().getTime() + (50*24*60*60*1000))
  };

  // if you know the Event ID, set it here:
  options.id = '123456';

  // you can optionally pass in a few other properties, any event containing these will be returned:
  options.title = 'groceries';
  options.location = 'foo';
  options.notes = 'bar'; // iOS only

  Calendar.findEvents(options).then(
      function(events) {
        console.log(JSON.stringify(events));
      },
      function(error) {
        console.log("Error finding Events: " + error);
      }
  );

The returned 'events' object is an array of JSON events with these properties:

id
title
location
notes
url
startDate
endDate
allDay
calendar {id, name}
reminders {minutes}
recurrence {frequency, interval, endDate}
attendees {name, email, url, status, role, type}

deleteEvents

Usage is largely the same as findEvents, only the result is a bit different ;)

var options = {
    // when searching, dates are mandatory - the event must be within this interval
    startDate: new Date(new Date().getTime() - (50*24*60*60*1000)),
    endDate: new Date(new Date().getTime() + (50*24*60*60*1000))
  };

  // if you know the Event ID, set it here:
  options.id = '123456';

  // you can optionally pass in a few other properties, any event containing these will be deleted:
  options.title = 'groceries'; // events _including_ this string will be included in the selection
  options.location = 'foo';
  options.notes = 'bar'; // iOS only

  Calendar.deleteEvents(options).then(
      function(deletedEventIds) {
        console.log(JSON.stringify(deletedEventIds));
      },
      function(error) {
        console.log("Error deleting Events: " + error);
      }
  )

listCalendars

Calendar.listCalendars().then(
      function(calendars) {
        // a JSON array of Calendar objects is returned, each with an 'id' and 'name'
        console.log("Found these Calendars on the device: " + JSON.stringify(calendars));
      },
      function(error) {
        console.log("Error while listing Calendars: " + error);
      }
  )

deleteCalendar

TypeScript

import * as Calendar from "nativescript-calendar";

Calendar.deleteCalendar({
  name: "My Calendar name"
}).then(id => {
  // id is null if nothing was deleted
  console.log(`Deleted Calendar with id ${id}`);
});

使用案例

react-native-webview与前端的交互

使用方法使用npm或者yarn安装react-native-webview。基本使用 <WebView //html文件放在Android --> app --> src --> main --> assets文件夹下，html代码下面会给出来可以参考 source={{uri: 'file:///android_asset/index.html'}}
