LaunchScreen.storyboard bug in swift

Question

I was using LaunchScreen.storyboard without problems. but I changed LaunchScreen.storyboard file name to LaunchScreen2.storyboard since I hoped not to use the splash image. (I thought it could decrease loading time) However, I couldn't see the loading time differences.

So I renamed the file to LaunchScreen.storyboard to use splash image again. But the problem began from here.

Even though I change images in LaunchScreen.Storyboard:-

1. Only black screen is shown shortly when I run my app on simulators.
2. Old LaunscScreen.storyboard is shown when I run the app on my iPad.

I took some.. actions but it didn't work. (use image in Assets.cassettes, make sure Launch Screen File name in project option)

Is there anyone who can help me?

*I attached screenshots

(I'm using the latest Xcode, Version 9.1 (9B55))

Answer 1

这是iOS问题（操作系统级别）iOS缓存LaunchScreen.storyboard图像资源并重复使用

为什么你的行动不起作用，因为

模拟器上的
1. app尚未缓存LaunchScreen，因此显示黑屏（未找到LaunchScreen.storyboard）
2. iPad已缓存并使用了LaunchScreen资源（LaunchScreen.storyboard），因此显示了旧的资源

常见的解决方案是删除app或关闭，并在iPhone或iPad上删除兑现资源。 iOS在Srpingboard（操作系统级别）中管理此资源所以它不是一个完整的解决方案，但促使缓存从操作系统中快速删除。只是等待..直到iOS擦除它

Answer 2

看起来像LunchScreen没有正确显示。 可能的解决方案是：

1. 首先重新启动Xcode
2. 从模拟器和设备中删除应用
3. 重新打开Xcode构建并重新运行

希望它能奏效。

如果没有，请查看info.plist以获取LunchScreen.storyboard名称。将屏幕背景颜色设置为白色，并为启动屏幕图像设置另一种颜色。一次又一次检查。希望你能找到解决方案。

我想我发现问题的根本原因持续了一个多月。

至少在我的情况下，问题发生是因为LaunchScreen文件中没有入口点。 设置入口点后，我可以看到LaunchScreen。
