didUpdatePushCredentials未被调用

Question

我想在我的iOS应用程序中实现VoIP通知，但 didUpdatePushCredentials 方法从未被调用，我无法获取设备令牌。

我在应用程序中实现了APNS，这两个服务可能冲突吗？

这是我的AppDelegate代码

- (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");
}

• 我已启用远程通知，已安装证书和配置文件。
• 我可以使用APNS推送标准通知。

任何让它运作的解决方案？

Answer 1

如果您正在运行较新的xcode（我在xcode 9上），则VOIP不在Capabilities选项卡的Background部分中。这样可以防止调用didUpdatePushCredentials！

诀窍是你必须进入你的plist，并且在Required Background Modes中你需要添加App provides Voice over IP services。

我无法相信Apple已经对我们这样做了。我浪费了8个小时的工作日来寻找这个简单的解决方案。

使用以下代码并确保遵循以下事项。

**`**// 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

中调用以下方法

其他删除方法如下

- (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);
}

//在项目能力中确保这一点

1）背景模式开启

2）VOIP

3）背景提取

4）remotenotification

5）别忘了导入代表

在背景模式

中

Answer 3

证书存在问题。

重新生成并重新导入证书并解决问题。

对我来说，解决方案是启用：

P.S。我没有忘记启用 但是，启用一般推动也很重要。完整的代码是：

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)")
    }
}
