用于关闭灯箱的完成块

Question

有没有办法在lightBox被解雇后立即执行代码？我正在寻找相当于完成块：

Navigator.dismissLightBox();
//wait for it to dismiss and execute code

Answer 1

您可以在passProps中传递回调并在componentwillunmount

中调用该回调

Navigation.showLightBox({
  screen: "example.LightBoxScreen",
  passProps: {
    onDismiss: () => console.log('dismissed')
  }
});
