添加 AppDelegate 后应用程序为空

Question

我在 Cordova 中有一个 iOS 应用程序，它使用 OneSignal 实现推送通知。

我已按照给定的文档中的所有步骤进行操作 here

问题是，当我使用 XCode 安装应用程序时，应用程序询问，

AppName Would like to send you notification

但之后一切都黑屏了。

我假设是因为下面的AppDelegate.m文件

    // Replace '11111111-2222-3333-4444-0123456789ab' with your OneSignal App ID.
    [OneSignal initWithLaunchOptions:launchOptions
                               appId:@"11111111-2222-3333-4444-0123456789ab"
            handleNotificationAction:nil
                            settings:@{kOSSettingsKeyAutoPrompt: @false}];
    OneSignal.inFocusDisplayType = OSNotificationDisplayTypeNotification;

    // Recommend moving the below line to prompt for push after informing the user about
    //   how your app will use them.
    [OneSignal promptForPushNotificationsWithUserResponse:^(BOOL accepted) {
        NSLog(@"User accepted notifications: %d", accepted);
    }];

    return YES;
}

@end

ID我也换了。在 XCode 日志中它显示了一些警告，它们是

Answer 1

请在您的 appdelegate 中添加以下方法来处理通知。

   -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSLog(@"Application registered for notification");
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"Failed to register notification for application");
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{

}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{

}

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{

}

Answer 2

我认为有两个不同的问题。黑屏问题的原因可能是应用程序不知道要显示哪个 View Controller。如果您使用的是故事板，则可以将所需的视图控制器设置为 'Initial View Controller'。

或者您可以添加

self.window.rootViewController = self.viewController; [self.window makeKeyAndVisible];

到结尾：

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

就在return YES;
