如何在 Objective C 中使用 CallKit

Question

我正在使用 WWDC CallKit session，我对它的概念很满意，但不知道如何开始。

另外，我遵循了 Apple 开发人员的 CallKit 示例代码，即 SpeakerBox。但是这个在 Swift.

需要建议！！

提前致谢

给你。 Objective c.

中有完整示例

CallKit 框架提供对 VoIP 功能的编程访问，以及呼叫阻止和识别。注意：此示例需要构建设备。

首先在 App delegate 中添加以下代码。

 #import <Intents/Intents.h>
 #import <PushKit/PushKit.h>
 @interface AppDelegate () <PKPushRegistryDelegate>

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     // Override point for customization after application launch.
     PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
     pushRegistry.delegate = self;
     pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];

    return YES;
}

然后在app delegate中也添加以下方法。

 - (BOOL)application:(UIApplication *)application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray * _Nullable))restorationHandler {
    if ([userActivity.interaction.intent isKindOfClass:[INStartAudioCallIntent class]]) {
        INPerson *person = [[(INStartAudioCallIntent*)userActivity.interaction.intent contacts] firstObject];
        NSString *phoneNumber = person.personHandle.value;
        CallViewController *viewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil]instantiateViewControllerWithIdentifier:@"CallViewController"];
        viewController.phoneNumber = phoneNumber;
        UIViewController *mainViewController = self.window.rootViewController;
        [mainViewController presentViewController:viewController animated:YES completion:nil];
    }
    return YES;
}

#pragma mark - PKPushRegistryDelegate

 - (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type {
    if([credentials.token length] == 0) {
        NSLog(@"voip token NULL");
        return;
    }
}

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {
    NSString *uuidString = payload.dictionaryPayload[@"UUID"];
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:uuidString];
    NSString *phoneNumber = payload.dictionaryPayload[@"PhoneNumber"];
    CallViewController *viewController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil]instantiateViewControllerWithIdentifier:@"CallViewController"];
    viewController.phoneNumber = phoneNumber;
    viewController.isIncoming = YES;
    viewController.uuid = uuid;
    UIViewController *mainViewController = 
    self.window.rootViewController;
    [mainViewController presentViewController:viewController animated:YES completion:nil];
}
