ios 启动屏幕故事板不显示图像

Launch Screen storyboard not displaying image

提问by shadowarcher

I'm trying to get an image to display as the launch screen from my Launch Screen.storyboard file, however the image never displays. I have labels that show up fine, but the image doesn't appear.

我试图从我的 Launch Screen.storyboard 文件中获取一个图像作为启动屏幕显示，但是该图像永远不会显示。我有显示正常的标签，但图像没有出现。

This is how the launch screen looks in the Launch Screen.storyboard file:

这是启动屏幕在 Launch Screen.storyboard 文件中的外观：

However when I run the app on the simulator (as well as on the physical device) this is what shows up:

但是，当我在模拟器（以及物理设备上）上运行该应用程序时，会显示以下内容：

As you can see, the label "Test" shows up fine, however the image does not display. I'm really not sure why this is happening and nothing I try seems to work. If anyone has any ideas of how to fix this it would be greatly appreciated.

如您所见，标签“Test”显示正常，但图像不显示。我真的不确定为什么会发生这种情况，而且我尝试的任何方法似乎都不起作用。如果有人对如何解决此问题有任何想法，将不胜感激。

After restarting Xcode, cleaning the build and a number of the other suggestions on SO about this problem. What actually fixed it for me was a hard reboot of the device. (I wasted over an hour on this)

重新启动 Xcode 后，清理构建和一些关于此问题的其他建议。实际上为我修复的是设备的硬重启。（我浪费了一个多小时）

I suppose it just goes to show that the old saying have you turned it off and on again is still true for the latest gadgets!

我想这只是表明，对于最新的小工具来说，您是否将其关闭并再次打开这句老话仍然适用！

I was messing around with this for hours too. But i found the solution now. You need to add the image to your projectand also to the assets.xcassets via drag and drop.

我也在这个问题上折腾了好几个小时。但我现在找到了解决方案。您需要将图像添加到您的项目以及通过拖放操作添加到 assets.xcassets 中。

Had the same issue, adding the image to the "Build Phases -> Copy Bundle Resources" fixed it for me.

有同样的问题，将图像添加到“构建阶段 - > 复制捆绑资源”为我修复了它。

If not working, delete derived data. Xcode Preference->Locationtab->Derived data. Then do follow above steps.

如果不起作用，请删除派生数据。Xcode Preference->Locationtab->Derived data。然后按照上面的步骤操作。

It happened to me and makes me crazy, beyond get me lose some minutes 'til I figure it out.

它发生在我身上，让我发疯，除了让我失去几分钟，直到我弄清楚为止。

So, like was said before:

所以，就像之前说的：

1. Import the desired image to your Xcode project (just drag and drop it)
2. Change its Constraints and Alignment
3. Update frames resolving Auto Layout issues
4. In the Attributes inspector tab menu (generally in right corner menu xCode), on Image view > Image, remove image extension (.png or .jpg) - that's the trick

1. 将所需的图像导入您的 Xcode 项目（只需拖放即可）
2. 改变它的约束和对齐
3. 更新框架以解决自动布局问题
4. 在属性检查器选项卡菜单（通常在右上角菜单 xCode）中，在图像视图 > 图像上，删除图像扩展名（.png 或 .jpg） - 这就是诀窍

On the design screen, it will not appear, but when you run your app, it will be shown.

在设计屏幕上，它不会出现，但是当您运行您的应用程序时，它会显示出来。

I hope it can help!

我希望它能有所帮助！

At last, restart the phoneworks for me!!

最后，重启手机对我有用！！

I have spent hours on this issue. Had tried change the images name, delete the whole image assets, modify info.plist, restart Xcode and even tried to set all the attributes of the images(which you can tell how desperate I was).

我在这个问题上花了几个小时。曾尝试更改图像名称，删除整个图像资产，修改 info.plist，重新启动 Xcode，甚至尝试设置图像的所有属性（您可以看出我有多绝望）。

This issue is related to the Assets.xcassetsto fix it you must add the image as resource but not in the xcassetsfolder and then should work just fine

此问题与Assets.xcassets相关以修复它您必须将图像添加为资源但不在xcassets文件夹中，然后应该可以正常工作

In my case, resetting content and settings for simulator fixed the problem.

就我而言，重置模拟器的内容和设置解决了这个问题。
