反应本机应用程序停留在闪屏

Question

我有一个反应的本地应用程序编码Ignite Red Boilerplate和应用程序有时只停留在启动屏幕（启动屏幕）。然后我回到之前的提交并再次启动应用程序，并按预期开始工作。

为了帮助您找出解决办法：

1. 我使用这个闪屏模块：React native splash screen
2. 点燃红色带有一个登录Saga，我又增加注册的传奇，并且它的工作很好，直到我实际卸载应用程序并重新安装它，然后当应用程序安装，它永远不会通过启动画面。
3. 我没有看到任何日志任何地方，试图在Xcode中运行它，但没有调试日志，我怎么看到以下事情在模拟器系统日志中，我在这里粘贴一些东西。希望有些身体可以帮助我解码它。

正如你可以看到在系统日志中，前6项是我开始了那些获得了完美的射击动作。然后这个没有连接的处理程序。

Answer 1

您有一个例外：

undefined is not an object (evaluating 'el.props.component') 

搜索您的项目el.props.component - 这将是被启动时更可能在安装的组件。无论是或者你滥用拥有该代码的第三方组件。
