添加 AppDelegate 后应用程序为空白

Question

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

我已按照here给出的文档中的所有步骤进行操作

问题是，当我使用 XCode 安装应用程序时，应用程序会询问，

AppName 想给你发送通知

但在那之后一切都黑屏了。

我认为这是因为 AppDelegate.m 文件如下

    // Replace '11111111-2222-3333-4444-0123456789ab' with your OneSignal App ID.
    [OneSignal initWithLaunchOptions:launchOptions
                               appId:@"11111111-2222-3333-4444-0123456789ab"

                            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

我也更换了身份证。并且在 XCode 日志中显示很少的警告，即

Answer 1

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。如果您使用情节提要，您可以将所需的视图控制器设置为“初始视图控制器”。

或者你可以添加

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

到结尾：

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

就在return YES;上方

Answer 2

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
{

}
