本クイックスタートではNotifyとTwilio NotifyサンプルiOS Appを使用してプッシュ通知を送信する方法をご紹介します。
To complete this guide you will need to have an Apple developer account, run Xcode on your machine, and have iOS Push Notifications configured.
コンソールでは、Notifyサービスを作成します。 SIDを書き留めておいてください！ 後ほどコードを記述する際に使用します。
We need to get the necessary information from our Twilio account. Here's what we'll need:
You will also need to create a push credential on the Twilio Console, and then configure it on your Notify service. You can upload your push credentials here. If you haven't set up the Apple Push Notification Service (APNS) for your app, you can do so by following the iOS push notification guide.
Functions is Twilio's serverless code execution environment that lets you write Node.js code that can respond to Twilio webhooks or to regular HTTP POST or GET requests.
You can also always write your own server code using any of Twilio's supported server side languages (Node.js, Python, Ruby, C#, Java, or PHP) - check out how to register bindings or how to send a notification in those languages.
The sample mobile app is already set up to communicate with Twilio Functions to register a device for notifications. You just need to create two Functions in your account from a template, and then specify the URL for one of those Twilio Functions in the source code to the app.
To get started with this, create a new Twilio Function on the Twilio Console's Manage Functions page. Choose the Twilio Notify Quickstart template from the list of templates.
After choosing the Twilio Notify Quickstart template, you'll be asked for one piece of configuration information - the Notification Service instance SID that you created at the beginning of this quickstart.
After entering that SID as the value, and clicking create, you will see two new Twilio Functions on your Functions page.
The first function is Register Binding - available at the /register-binding path. The quickstart mobile app sends an identity and the device token that it gets from the Apple Push Notification service to this function to create a binding. Notify uses these bindings to map the device that someone is using to their identity when you send a notification.
The second function is Send Notification - this is available at the /send-notification path. The mobile app does not use this function - instead you can use it to send notifications to yourself on the quickstart app.
If you select either function, you can see the Node.js source code, if you are curious to see how these are implemented.
Lastly, copy the URL for the register binding function - you will need that for the iOS app. Each account has a different subdomain for Twilio Functions - for instance, yours might be something like this:
Now that you have the Twilio Functions created, it's time to set up the iOS app!
To be able to receive Push Notifications, we need to run the Twilio Notify sample iOS app on a device, as Push Notifications do not work on the iOS Simulator.
To have the mobile app, running on your device, talking to your Twilio Functions, replace the server URL at the top of the
ViewController file with your Twilio Functions subdomain URL.
Next we need to create a Binding between user Identity and the device running the app. User Identity can be any unique identifier you choose, like a GUID, or a primary key. User identity should not be personally identifiable information (PII), such as a name or an email address.
In the Twilio Console, navigate to the
Twilio Notify Quickstart (Register Bindings) Function that you just created, and leave that web page open while you register with the app. That way, you can see logging information from your function.
If the binding request wasn't successful, you'll see an error message printed in the Twilio Function logs instead. If there was a problem with the iOS app connecting to the Twilio Function, the error message may be printed out to Xcode's console by the iOS app.
Identity as a unique identifier of a user. You should not use directly identifying information (aka personally identifiable information or PII) like a person's name, home address, email or phone number as
Identity because the systems that will process this attribute assume it is not directly identifying information.
To send a notification, you can use the
Twilio Notify Quickstart (Send Notification) Twilio Function you just created.
You can either send an HTTP GET or an HTTP POST request to the function. Typically, you would send a POST request to the function from your application (as you are performing an action, not retrieving information). If you don't have an easy way to POST a request (like Postman or curl), using GET is fine for testing your quickstart app.
For instance, you might make a request like:
Use the identity you used in the app. Because you registered a binding with Twilio, the server will send your device the 'Hello' message as a notification.
