コードスニペット(Push通知編 アプリ側）

Push通知のコードスニペット

実装手順

1. Push通知の設定
2. デバイストークンの送信
3. Push通知を受け取る

1. Push通知の設定

iOS7以下とiOS8以上で仕様が違う

import UIKit

class RemotePushManager {
    
    class func registerForRemoteNotifications(application: UIApplication) {
        
            if #available(iOS 8.0, *) {
                let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
                application.registerUserNotificationSettings(settings)
                application.registerForRemoteNotifications()
            } else {
                application.registerForRemoteNotificationTypes([.Alert, .Badge, .Sound])
            }
    }
}

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        RemotePushManager.registerForRemoteNotifications(application)
        return true
    }

2. デバイストークンの送信

自前サーバーへデバイストークンを送信する

    //MARK: - リモートプッシュ通知
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        
        let characterSet: NSCharacterSet = NSCharacterSet(charactersInString: "<>")
        
        let deviceTokenString: String = (deviceToken.description as NSString)
            .stringByTrimmingCharactersInSet(characterSet)
            .stringByReplacingOccurrencesOfString(" ", withString: "") as String
        print(deviceTokenString)

        //TODO : デバイストークンの送信        
    }
    
    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    }

3. Push通知を受け取る

import UIKit

class RemotePushManager {
        
    class func received(application: UIApplication, launchOptions: [NSObject: AnyObject]?) {
        
        if let launchOptions = launchOptions {
            
            if let aps = launchOptions["aps"] as? [NSObject: AnyObject] {
                
                print(aps["alert"])
                print(aps["sound"])
                print(aps["badge"])
            }
        }
    }
}

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        RemotePushManager.registerForRemoteNotifications(application)
        
        if let launchOptions = launchOptions {
            
            if let option : NSDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {
            
                self.application(application, didReceiveRemoteNotification: option as [NSObject : AnyObject])
            }
        }
        return true
    }

    //Push通知受信時とPush通知をタッチして起動したとき
    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        
        RemotePushManager.received(application, launchOptions: userInfo)
        
        switch application.applicationState {
         case .Inactive:
            break
        case .Active:
            break
        case .Background:
            break
        }
    }
}

APNSから受信するデータは、下記のようなイメージ

{
  "aps":{
    "alert": "New Message",
    "badge": 3,
    "sound": "sound1.aiff",
    "content-available": 1  // -> サイレントプッシュ
  },
  "name": "value"
}
