XCode 控制台：警告！唯一的人格是模糊的；这可能会导致不稳定的行为 - 在键盘扩展中

Question

我有一个 iOS 应用程序，其中包含自定义键盘扩展及其容器应用程序。当我尝试调试自定义键盘扩展时，我在 XCode 控制台中收到以下相当令人不安的日志：

EasyType Keyboard[84937:5754706] [lifecycle] [u 9061FF85-F4D2-401A-94C2-73377E20E419] [com.easytype.EasyType.Keyboard(1.7.1)] WARNING! Sole personality is ambiguous; this may lead to erradic behavior; personalities: {
    "com.easytype.EasyType.Keyboard" =     {
        685 = "<PKServicePersonality: 0x283175340; core = <PKPlugInCore: 0x283175340; uuid = [9061FF85-F4D2-401A-94C2-73377E20E419], identifier = [com.easytype.EasyType.Keyboard(1.7.1)], isAppExtension = 1, onSystemVolume = 0, containingBundle = [(null)], lastModified = 0, discoveryInstanceUUID = [(null)], path = [/private/var/containers/Bundle/Application/762C0B3C-A600-4AB4-AB84-AB2019FA053C/EasyType.app/PlugIns/EasyType Keyboard.appex]>, host pid = 685>";
        84881 = "<PKServicePersonality: 0x2831782a0; core = <PKPlugInCore: 0x2831782a0; uuid = [DAEEF528-9AB6-4482-95E9-03E6BB353BBD], identifier = [com.easytype.EasyType.Keyboard(1.7.1)], isAppExtension = 1, onSystemVolume = 0, containingBundle = [(null)], lastModified = 0, discoveryInstanceUUID = [(null)], path = [/private/var/containers/Bundle/Application/762C0B3C-A600-4AB4-AB84-AB2019FA053C/EasyType.app/PlugIns/EasyType Keyboard.appex]>, host pid = 84881>";
    };
}

com.easytype.EasyType.Keyboard

是键盘扩展的捆绑 ID。该项目休眠了一段时间，当我再次开始工作时，此日志开始显示。我该如何解决这个问题？

还有另一个版本的日志，有时出现在更常见的日志之上：

EasyType Keyboard[85190:5767015] [lifecycle] WARNING! Sole personality requested when nil; THIS MAY BE A SPURIOUS LAUNCH OF THE PLUGIN due to a message to an XPC endpoint other than the main service endpoint; personalities: {

    };
}

Answer 1

该警告似乎不会造成任何问题，只是给开发人员的一条消息。

但是，自定义键盘之间切换的生命周期是您可能需要关注的事情，特别是如果有需要加载/释放的服务。

以下是我为可能需要的人记录的生命周期：

出现系统级警报（即连接到设备）：

willResignActive => didBecomeActive

切换到首页

willResignActive => viewWillDisappear => viewDidDisappear

关闭自定义键盘：

viewWillDisappear => viewDidDisappear => viewWillDisappear => viewDidDisappear => deinit

切换到其他未打开自定义键盘的应用程序：

`willResignActive => viewWillDisappear => viewDidDisappear => deinit`

使用打开的自定义键盘在应用程序之间切换：

    `willResignActive => [Erratic behavior warning listed] => viewDidLoad
 => viewWillAppear => didBecomeActive => viewWillDisappear => didEnterBackground
 => viewDidDisappear => first keyboard may not deinit`
