VoIP-Pushes

In iOS 8 hat Apple PushKit und VoIP-Pushes eingeführt – eine neue Art von Push-Benachrichtigungen. Zusätzlich zur Standard-Push-Funktionalität ermöglicht ein VoIP-Push der App, Code auszuführen, bevor die Benachrichtigung dem Benutzer angezeigt wird.

1. Fügen Sie das PushwooshVoIP-Modul zu Ihrem Projekt hinzu.

Swift Package Manager

Cocoapods

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  pod 'PushwooshXCFramework'
  pod 'PushwooshFramework/PushwooshVoIP'

end

2. Fügen Sie im Tab Signing & Capabilities die Fähigkeit Voice over IP hinzu, indem Sie das Kontrollkästchen aktivieren, wie im folgenden Screenshot gezeigt:

3. Initialisieren Sie das PushwooshVoIP-Modul, wie im folgenden Code gezeigt.

import UIKit
import PushwooshFramework
import PushwooshVoIP
import CallKit
import PushKit

@main
class AppDelegate: UIResponder, UIApplicationDelegate, PWVoIPCallDelegate {

    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        /// Initializes the Pushwoosh VoIP module.
        ///
        /// - Parameters:
        ///   - supportVideo: A Boolean value indicating whether video calls are supported.
        ///   - ringtoneSound: The name of the custom ringtone sound file to be used for incoming calls (e.g. `"mySound.caf"`).
        ///   - handleTypes: The type of call handle to support. Possible values:
        ///     - `1` – Generic
        ///     - `2` – Phone number
        ///     - `3` – Email address
        Pushwoosh.VoIP.initializeVoIP(true, ringtoneSound: "mySound.caf", handleTypes: 1)

        // Set delegate to receive VoIP call events
        Pushwoosh.VoIP.delegate = self

        return true
    }

    // MARK: - Required PWVoIPCallDelegate Callbacks

    func voipDidReceiveIncomingCall(payload: PushwooshVoIP.PWVoIPMessage) {
        // Handle incoming VoIP push
    }

    func pwProviderDidReset(_ provider: CXProvider) {
        // Handle provider reset
    }

    func pwProviderDidBegin(_ provider: CXProvider) {
        // Handle provider activation
    }
}

4. Das PWVoIPCallDelegate-Protokoll definiert erforderliche und optionale Callbacks zur Handhabung des VoIP-Anruf-Lebenszyklus und der CallKit-Interaktionen.

@objc public protocol PWVoIPCallDelegate: NSObjectProtocol {

    /// Called when an incoming VoIP push is received.
    @objc func voipDidReceiveIncomingCall(payload: PushwooshVoIP.PWVoIPMessage)

    /// Optional: Called when the incoming call was successfully reported to CallKit.
    @objc optional func voipDidReportIncomingCallSuccessfully(voipMessage: PushwooshVoIP.PWVoIPMessage)

    /// Optional: Called when reporting the incoming call to CallKit failed.
    @objc optional func voipDidFailToReportIncomingCall(error: Error)

    /// Optional: Called when a new outgoing call is started.
    @objc optional func startCall(_ provider: CXProvider, perform action: CXStartCallAction)

    /// Optional: Called when an active call is ended.
    @objc optional func endCall(_ provider: CXProvider, perform action: CXEndCallAction, voipMessage: PushwooshVoIP.PWVoIPMessage?)

    /// Optional: Called when an incoming call is answered.
    @objc optional func answerCall(_ provider: CXProvider, perform action: CXAnswerCallAction, voipMessage: PushwooshVoIP.PWVoIPMessage?)

    /// Optional: Called when the call is muted or unmuted.
    @objc optional func mutedCall(_ provider: CXProvider, perform action: CXSetMutedCallAction)

    /// Optional: Called when the call is held or unheld.
    @objc optional func heldCall(_ provider: CXProvider, perform action: CXSetHeldCallAction)

    /// Optional: Called when a DTMF tone is played.
    @objc optional func playDTMF(_ provider: CXProvider, perform action: CXPlayDTMFCallAction)

    /// Called when the CallKit provider is reset.
    @objc func pwProviderDidReset(_ provider: CXProvider)

    /// Called when the CallKit provider begins.
    @objc func pwProviderDidBegin(_ provider: CXProvider)

    /// Optional: Provides the CallKit call controller instance.
    @objc optional func returnedCallController(_ controller: CXCallController)

    /// Optional: Provides the CallKit provider instance.
    @objc optional func returnedProvider(_ provider: CXProvider)

    /// Optional: Called when the audio session is activated.
    @objc optional func activatedAudioSession(_ provider: CXProvider, didActivate audioSession: AVAudioSession)

    /// Optional: Called when the audio session is deactivated.
    @objc optional func deactivatedAudioSession(_ provider: CXProvider, didDeactivate audioSession: AVAudioSession)
}

5. Laden Sie Ihr VoIP-Zertifikat gemäß der Konfigurationsanleitung in das Pushwoosh Control Panel hoch und wählen Sie das Produktions-Gateway.

Das war’s!
