Unfortunately, the cold hard truth is that users will sometimes have to close the app and perform other activities. Laundry doesn’t fold itself, you know . In i. OS 9, push notifications can: Display a short text message. Play a notification sound. Set a badge number on the app’s icon. Provide actions the user can take without opening the app. Be silent, allowing the app to wake up in the background and perform a task. This push notifications tutorial will go over how push notifications work, and let you try out their features. Before you get started, you will need the following to test push notifications: An i. OS device. Push notifications do not work in the simulator, so you’ll need an actual device. Since Xcode 7, you can now test apps on your device without a program membership. However, to configure push notifications you need a push notification certificate for your App ID, which requires the program membership. Sending push notifications is a responsibility of the app’s server- component and is usually implemented differently from one app to the next. Many apps use third- parties (ex. Parse. com or Google Cloud Messaging) to send push notifications, while others use custom solutions and/or popular libraries (ex. Houston). To get started, download the starter project of Wender. Cast. Wender. Cast is everyone’s go- to source for raywenderlich. Open Wender. Cast. Xcode and take a peek around. Build and run to see the latest podcasts: The problem with the app is that it doesn’t let users know when a new podcast is available. It also doesn’t really have any news to display.

This is quite important, since you don’t want anyone else to send push notifications to your users. What this means is that there are quite a few hoops to jump through to configure apps for push notifications. Enabling the Push Notification Service. The first step is to change the App ID. Go to App Settings - > General and change Bundle Identifier to something unique: Next, you need to create an App ID in your developer account that has the push notification entitlement enabled.

That’s all you need to configure for now. Registering for Push Notifications. There are two steps to register for push notifications. First, you must obtain the user’s permission to show any kind of notification, after which you can register for remote notifications. If all goes well, the system will then provide you with a device token, which you can think of as an “address” to this device. In Wender. Cast, you will register for push notifications immediately after the app launches. Open App. Delegate. App. Delegate: func register. For. Push. Notifications(application: UIApplication). Under Mobile phone notifications, clear the box next to the notification service you want to disable, and then click Save. Keep in mind: If you turn off push notifications, users still receive all alerts when they start up.For the UIUser. Notification. Types, you can use any combination of the following. Badge allows the app to display a number on the corner of the app’s icon. Sound allows the app to play a sound. Alert allows the app to display text. The set of UIUser. Notification. Categorys that you currently pass nil to allows you to specify different categories of notifications your app can handle. This becomes necessary when you want to implement actionable notifications, which you will use later. Add a call to register. For. Push. Notifications(. When the app launches, you should receive a prompt that asks for permission to send you notifications: Tap OK and poof! The app can now display notifications.

This one is very different from the previous one you passed in. That one specified the settings you want, while this one specifies the settings the user has granted. It’s extremely important to call register. User. Notification. Settings(. This is because the user can, at any time, go into the Settings app and change the notification permissions. This is slightly easier, since you don’t need more permissions from the user. Add the following two methods to App. Delegate: func application(application: UIApplication, did. Register. For. Remote. Notifications. With. Device. Token device. Token: NSData). The device token is the fruit of this process. It is a token provided by APNS that uniquely identifies this app on this particular device. When sending a push notification, the app uses device tokens as “addresses” to direct notifications to the correct devices. Note: There are several reasons why registration might fail. Most of the time it’s because the app is running on a simulator, or because the App ID configuration was not done properly. The error message generally provides a good hint as to what is wrong. That’s it! Make sure you are running on a device, and you should receive a device token in the console output. Here’s what mine looks like: Copy this token somewhere handy.

Token to the one you received earlier, and $passphrase to the password you gave your push certificate when exporting: // Put your device token here (without spaces): $device. Token='4. 3e. 79. Put your private key's passphrase here: $passphrase='Wender. Cast. Push'; Open your terminal, cd to the folder containing newspush. Breaking News''https: //raywenderlich. If all goes well, your terminal should display: Connected to APNS. Message successfully delivered. You should receive your first push notification: Note: You won’t see anything if the app is open and running in the foreground. The notification is delivered, but there’s nothing in the app to handle it yet. Simply close the app and send the notification again. Common Issues. There are a couple problems that might arise: Some notifications received but not all: If you! That is intended behaviour. APNS maintains a Qo. S (Quality of Service) queue for each device with a push app. The size of this queue is 1, so if you send multiple notifications, the last notification is overridden. Problem connecting to Push Notification Service: One possibility could be that there is a firewall blocking the ports used by APNS. Make sure you unblock these ports. Another possibility might be that the private key and CSR file are wrong. Remember that each App ID has a unique CSR and private key combination. Anatomy of a Basic Push Notification. Before you move on to Task 3, handling push notifications, take a look at newspush. Pay attention to lines 3. Here the payload body is created and encoded as JSON. This is what actually gets sent to APNS. In this case, the payload looks like this. In this example, “aps” contains the fields “alert,” “sound,” and “link. You can add custom fields to the payload like this and they will get delivered to your application. Since you aren’t handling it inside the app yet, this key/value pair currently does nothing.
