[iOS] AppDelegateのPush通知用メソッドチートシート

毎回コピペするので。

AppDelegate.swift

class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        registerForRemoteNotifications(application)

        if let userInfo = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] {
            // アプリが起動していない時にpush通知が届き、push通知から起動した場合
        }

        //...
    }

    //...
}

AppDelegate+RemoteNotifications.swift

import Foundation

extension AppDelegate {

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

    // Push通知登録完了
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData ) {
        print("deviceToken: \(deviceToken.description)")
        let deviceTokenString: String = deviceToken.description
            .stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
            .stringByReplacingOccurrencesOfString(" ", withString: "")
        print("deviceTokenString \(deviceTokenString)")
    }

    // Push通知利用不可
    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
        print("devideToken register error: " + "\(error)")
    }

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        switch application.applicationState {
        case .Active:
            // アプリ起動中にPush通知を受信したとき
            break
        default:
            // アプリがバックグラウンドにいる状態で、Push通知から起動したとき
            break
        }
    }
}
