这是我为使其工作所做的工作：
!NoteThis also works for .xib files, which comes with React Native init
!注意这也适用于 React Native init 附带的 .xib 文件
Adding the image file
添加图像文件
1)Under image.xcassets, right click and choose New Image Set. Create three different sizes of your image (@1x, @2x, @3x) and add the images by dragging them into the slots for 1x, 2x, 3x. For 3x I suggest a size of more than 1200 px.
1)在 image.xcassets 下，右键单击并选择New Image Set。创建三种不同尺寸的图像（@1x、@2x、@3x）并通过将图像拖入 1x、2x、3x 的插槽来添加图像。对于 3x，我建议大小超过 1200 像素。
2)Name the new image set something, for intance: splash
2）命名新图像集的东西，例如：飞溅
Creating the launch screen

1)Right-click your project, click New File..., and add a Launch Screen.
1)右键单击您的项目，单击New File...，然后添加一个 Launch Screen。

10)Go to Size Inspector (ruler icon, see screenshot)and choose a width and a height that looks good (this will scale to other screen sizes).
10）转到尺寸检查器（标尺图标，见截图）并选择一个看起来不错的宽度和高度（这将缩放到其他屏幕尺寸）。
11)Drag your image into the center of the screen until you see both a horizontal and vertical blue line
11)将图像拖到屏幕中央，直到看到水平和垂直的蓝线
12)Lastly, under Autoresizingchange the window with the arrows, so it looks like in the screenshot above. All outer arrows should be deselected and all inner arrows selected.
12)最后，在Autoresizing下用箭头更改窗口，所以它看起来像上面的屏幕截图。应取消选择所有外部箭头并选择所有内部箭头。
