iOS Cordova崩溃：应用程序试图以模态方式呈现活动控制器UIViewController

几周来，我一直在解决这个问题，不知道是什么导致了这次崩溃

用户报告：我的一些用户报告应用程序一启动就会崩溃。甚至在登录屏幕出现之前

崩溃报告：我在我的应用程序中心看到很多崩溃报告，其中有这样一条消息：

SIGABRT：应用程序试图以模态方式呈现活动控制器。

设备和用户：似乎只有大约10%的我的用户会发生这种崩溃。他们都是iOS用户。Android用户没有这个问题

尝试的步骤：

> cordova plugin ls
code-push 3.0.1 "CodePushAcquisition"
cordova-plugin-android-permissions 1.0.2 "Permissions"
cordova-plugin-appcenter-analytics 0.5.1 "App Center Analytics for Cordova"

cordova-plugin-splashscreen 5.0.3 "Splashscreen"
cordova-plugin-statusbar 2.4.4-dev "StatusBar"
cordova-plugin-whitelist 1.3.4 "Whitelist"
cordova-plugin-zip 3.1.0 "cordova-plugin-zip"
ionic-plugin-deeplinks 1.0.15 "Ionic Deeplink Plugin"
onesignal-cordova-plugin 2.7.0 "OneSignal Push Notifications"

老实说，我不知道从哪里开始。我不知道从哪里开始寻找，什么可能导致问题。我怀疑问题来自其中一个插件，但它是哪个插件？此外，到目前为止，我跟踪的插件作者中没有一个对我的问题做出回应。更令人沮丧的是，我根本无法复制这个问题。我在模拟器中尝试了几乎所有报告的设备和它们的iOS，但对我来说一切都很好。我也在iPhone8上试用过，效果很好。尽管一些用户继续报告它不断崩溃，但他们不知道如何解决这个问题，也不知道是哪个插件导致了这个问题

有人能帮我看看下一步我能做些什么吗？任何建议都是有益的。您是否怀疑我的应用程序中的任何插件会导致此问题？我的应用程序是在爱奥尼亚科尔多瓦开发的（爱奥尼亚v1）。我知道代码的角度部分，但不知道目标C

下面是我从应用中心得到的撞车报告截图，它似乎没有指出太多的来源

我遇到的问题是由于我的ionic cordova应用程序中使用了一个插件（MediaPicker）。这是该插件最近的一次提交，在某些iOS中导致了此崩溃错误。我把这个插件恢复到订单版本，似乎可以解决这个错误。我已经向插件的作者报告了这一点，这样他就可以研究它了
