[英]application:didFinishLaunchingWithOptions is not being called
我正在使用推送通知。 我通读了Apple的编程指南，以了解在发出远程或本地通知的情况下，将调用application：didFinishLaunchingWithOptions并将有效负载保存在launchOptions中。 如果有通知，我可以从那里响应推送。 我正在测试两个设备上的推送。 一个发出推送，第二个收到推送。 我在两台设备上都运行了该应用程序，第二台设备保持打开状态，第二台设备退出到主屏幕，然后关闭了手机以等待通知（尽管我没有在xcode上关闭该应用程序）。 我发出了一个推送，并且在接收器设备上收到了推送，但是使用NSLog时，似乎在打开推送时未调用application：didFinishLaunchWithOptions，并且在应用程序首次启动时仅调用了一次。 我没有提供代码，因为除了可以正常工作的推送之外，没有太多可用来测试的代码了。 有什么事吗 是在后台运行时响应打开的通知的正确方法吗？
如果仅通过按主屏幕按钮关闭应用程序，则该应用程序实际上不会再次启动，因此第二次将不会调用application:didFinishLaunchWithOptions
相反，将被称为- (void)applicationWillEnterForeground:(UIApplication *)application和- (void)applicationDidBecomeActive:(UIApplication *)application因此我建议处理applicationDidBecomeActive必要的任何事情，因为打开应用程序时会调用该方法＆回到前台。
如果您的应用程序在推送通知到达时在后台（或前台）运行，则获取通知有效负载的方法是application:didReceiveRemoteNotification:
