didUpdatePushCredentials未被調用

Question

我想在我的iOS應用程序中實現VoIP通知，但是didUpdatePushCredentials方法永遠不會被調用，我無法獲得設備令牌。

我在應用程序中實現了APNS，這兩個服務可能會發生沖突嗎？

這是我的AppDelegate代碼

- (void)application:(UIApplication *)application
    didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    LOGI(@"%@", NSStringFromSelector(_cmd));

    //register for voip notifications
    self->pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
    [self->pushRegistry setDelegate:self];
    [self->pushRegistry setDesiredPushTypes:[NSSet setWithObject:PKPushTypeVoIP]];

    NSLog(@"VoIP push registered");

}

#pragma mark - VoIP push methods

- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type {
    NSLog(@"voip token: %@", credentials.token);
}

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {
    NSDictionary *payloadDict = [payload.dictionaryPayload valueForKey:@"aps"];
    NSString *message = (NSString *)[payloadDict valueForKey:@"alert"];

    if ([UIApplication sharedApplication].applicationState == UIApplicationStateBackground) {
        UILocalNotification *localNotification = [[UILocalNotification alloc] init];
        localNotification.alertBody = [message stringByAppendingString:@" - voip"];
        localNotification.applicationIconBadgeNumber = 1;
        localNotification.soundName = @"notes_of_the_optimistic.caf";

        [[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];
    } else {
        dispatch_async(dispatch_get_main_queue(), ^{
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"VoIP notification" message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
            [alert show];
        });
    }


    NSLog(@"incoming voip notfication: %@", payload.dictionaryPayload);
}

- (void)pushRegistry:(PKPushRegistry *)registry didInvalidatePushTokenForType:(NSString *)type {
    NSLog(@"Voip token invalidate");
}

• 我啟用了遠程通知，安裝了證書和配置文件。
• 我可以使用APNS推送標准通知。

任何解決方案讓它工作？

Answer 1

如果您正在運行較新的xcode（我在xcode 9上），那么VOIP不在Capabilities選項卡的Background部分中。 這樣可以防止didUpdatePushCredentials ！

訣竅是你必須進入你的plist，在Required Background Modes你需要添加App provides Voice over IP services 。

我無法相信Apple已經對我們這樣做了。 我浪費了8個小時的工作日來尋找這個簡單的解決方案。

使用下面的代碼並確保遵循以下事項。

**`**// Register for VoIP notifications**`**

- (void) voipRegistration {
    dispatch_queue_t mainQueue = dispatch_get_main_queue();
    // Create a push registry object
    _voipRegistry = [[PKPushRegistry alloc] initWithQueue: mainQueue];
    // Set the registry's delegate to self
    [_voipRegistry setDelegate:(id<PKPushRegistryDelegate> _Nullable)self];
    // Set the push type to VoIP
    _voipRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
}

在didFinishLaunchingWithOptions調用Below方法

其他刪除方法如下

- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials: (PKPushCredentials *)credentials forType:(NSString *)type {
    // Register VoIP push token (a property of PKPushCredentials) with server

    if([credentials.token length] == 0) {
        NSLog(@"voip token NULL");
        return;
    }
    NSLog(@"%@",credentials.token);
}

//在項目功能中確保這一點

1）背景模式為ON

2）VOIP

3）背景提取

4）remotenotification

5）別忘了導入代表

在背景模式中

證書存在問題。

已重新生成並重新導入的證書和問題已修復。

對我來說，解決方案是：

PS我沒有忘記啟用 但實現普遍推動也很重要。 所以完整的代碼是：

import UIKit
import PushKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        voipRegistration()

        return true
    }

    // Register for VoIP notifications
    func voipRegistration() {
        let mainQueue = DispatchQueue.main
        // Create a push registry object
        let voipRegistry: PKPushRegistry = PKPushRegistry(queue: mainQueue)
        // Set the registry's delegate to self
        voipRegistry.delegate = self
        // Set the push type to VoIP
        voipRegistry.desiredPushTypes = [.voIP]
    }

}

extension AppDelegate: PKPushRegistryDelegate {
    func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType) {
        let token = pushCredentials.token.map { String(format: "%02.2hhx", $0) }.joined()
        print("voip token = \(token)")
    }

    func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) {
        print("payload = \(payload.dictionaryPayload)")
    }
}
