[英]application:didFinishLaunchingWithOptions is not being called
我正在使用推送通知。 我通讀了Apple的編程指南，以了解在發出遠程或本地通知的情況下，將調用application：didFinishLaunchingWithOptions並將有效負載保存在launchOptions中。 如果有通知，我可以從那里響應推送。 我正在測試兩個設備上的推送。 一個發出推送，第二個收到推送。 我在兩台設備上都運行了該應用程序，第二台設備保持打開狀態，第二台設備退出到主屏幕，然后關閉了手機以等待通知（盡管我沒有在xcode上關閉該應用程序）。 我發出了一個推送，並且在接收器設備上收到了推送，但是使用NSLog時，似乎在打開推送時未調用application：didFinishLaunchWithOptions，並且在應用程序首次啟動時僅調用了一次。 我沒有提供代碼，因為除了可以正常工作的推送之外，沒有太多可用來測試的代碼了。 有什么事嗎 是在后台運行時響應打開的通知的正確方法嗎？
如果僅通過按主屏幕按鈕關閉應用程序，則該應用程序實際上不會再次啟動，因此第二次將不會調用application:didFinishLaunchWithOptions
相反，將被稱為- (void)applicationWillEnterForeground:(UIApplication *)application和- (void)applicationDidBecomeActive:(UIApplication *)application因此我建議處理applicationDidBecomeActive必要的任何事情，因為打開應用程序時會調用該方法＆回到前台。
如果您的應用程序在推送通知到達時在后台（或前台）運行，則獲取通知有效負載的方法是application:didReceiveRemoteNotification:
