android - React-native Android：应用程序在恢复时卡在启动画面上

问题描述

恢复后我的应用卡在启动画面上：

这是我的依赖项：

这是问题期间来自 adb logcat 的日志：

任何想法？

谢谢 ！

解决方案

你应该SplashScreen.hide()从componentDidMount()函数中调用。

如果您愿意，可以添加延迟，例如：

import { InteractionManager } from 'react-native';

...

componentDidMount() {

  // Some code here if needed.

  InteractionManager.runAfterInteractions(() => {
    setTimeout(() => {
      SplashScreen.hide();
    }, 750);
  });
}

如果您必须从componentDidUpdate()（因为您需要准备一些数据）调用它，只需调用它，而不是从 if 语句内部。如果启动画面已经消失，SplashScreen.hide()不会造成任何伤害。

（记住这一点 -componentDidUpdate()在第一次渲染后不被调用，仅在第二次渲染之后）
