反應本機應用程序停留在閃屏

Question

我有一個反應的本地應用程序編碼Ignite Red Boilerplate和應用程序有時只停留在啓動屏幕（啓動屏幕）。然後我回到之前的提交併再次啓動應用程序，並按預期開始工作。

爲了幫助您找出解決辦法：

1. 我使用這個閃屏模塊：React native splash screen
2. 點燃紅色帶有一個登錄Saga，我又增加註冊的傳奇，並且它的工作很好，直到我實際卸載應用程序並重新安裝它，然後當應用程序安裝，它永遠不會通過啓動畫面。
3. 我沒有看到任何日誌任何地方，試圖在Xcode中運行它，但沒有調試日誌，我怎麼看到以下事情在模擬器系統日誌中，我在這裏粘貼一些東西。希望有些身體可以幫助我解碼它。

正如你可以看到在系統日誌中，前6項是我開始了那些獲得了完美的射擊動作。然後這個沒有連接的處理程序。

Answer 1

您有一個例外：

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

搜索您的項目el.props.component - 這將是被啓動時更可能在安裝的組件。無論是或者你濫用擁有該代碼的第三方組件。
