Xcode 9，iOS 10资产问题 [英] Xcode 9, iOS 10 issue with Assets

问题描述

我在使用iOS 10的设备上运行资产和Xcode 9 beta时遇到问题，它没有上传资产中的任何图像，因此在手机上我看不到任何资产！

I'm having a problem with assets and Xcode 9 beta running on devices with iOS 10. It doesn't upload any image from assets, so on the phone I can't see any asset!

如果我在情节提要中加载图像，则在我执行某些操作时，它只是不会在电话上显示任何图像(但会在情节提要中显示).

If I load images in the storyboard, it just doesn't show any image on the phone (but it shows in the storyboard), if I do something:

UIImage(named:"imageName")!

它崩溃并显示日志消息:

It crashes with log message:

***-[_ CUIThemePixelRendition _initWithCSIHeader:]，/BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreUI/CoreUI-428.6/CoreTheme/ThemeStorage/CUIThemeRendition.m:3788中的断言失败 无法加载从标识符为"myIdentifierName"的捆绑包中的笔尖引用的"imageName"图像

*** Assertion failure in -[_CUIThemePixelRendition _initWithCSIHeader:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreUI/CoreUI-428.6/CoreTheme/ThemeStorage/CUIThemeRendition.m:3788 Could not load the "imageName" image referenced from a nib in the bundle with identifier "myIdentifierName"

这很奇怪，因为在具有iOS 11 beta的另一台设备上运行的相同代码可以正常工作，而且我可以看到图像.

This is strange as the same code running on another device with iOS 11 beta works and I can see the images.

推荐答案

在iOS 10上测试应用程序时遇到了同样的问题. 查看Xcode 9 Beta发行说明，发现有关的已知问题:

I got same problem when I test app on iOS 10. Check the Xcode 9 beta release note and found known issues about that:

资产目录

对于使用Xcode 9构建的应用程序，在iOS 10或更早版本上找不到资产目录中的Jpeg资产.用于访问图像的API调用，例如UIImage.imageNamed:返回nil. (32524123) 解决方法:使用png资源或将应用测试限制为运行iOS 11或更高版本的设备.

• Jpeg assets in asset catalogs are not found on iOS 10 or earlier for apps built with Xcode 9. API calls for accessing the image such as UIImage.imageNamed: return nil. (32524123) Workaround: Use png resources or limit app testing to devices running iOS 11 or later.

将我所有的jpg素材资源转换为png后.很好哦...

After convert all my jpg asset to png. It's works well. Oh...
