iOS Xcode：我是否需要在xcode捆绑包中保留所有初始屏幕和应用程序图标图像的两个副本？

Question

I am little bit confused about whether I have to keep the splash screen and app icon images both in the root folder of xcode and inside resources folder or I need to put those in one place only. Currently I am storing the images at both the places as shown below.

As you can see here in the screenshot, there are two copies of all the splash screen and app icon images inside xcode bundle. Because of this I am getting copyPNGFileLib error while building the app.

Please advise me which is the correct approach to store splash screen and app icon related images inside xcode bundle.. THANKS in advance... :-)

Answer 1

Since Xcode 5 you should use the Asset Catalog feature, which removes the need for references to images, including App icons/launch images, in the project. This makes managing images much simpler and makes things more organized in the filesystem too.

The only limitation is images in the catalog are not localizable, AFAIK. So if you actually need diferent images for different locales, you have to keep these outside of the xcassets file.

You can convert your targets to using Asset Catalog by selecting your Project, then for each target in the Info tab you have options to migrate the Launch Images / App Icons to xcassets. I had issues with the automatic conversion though, so I just added an Asset Catalog to the project via New File and then added my images to it.

I actually don't have an answer for Xcode 4.x, but I strongly suggest you to move to Xcode 5 if possible. The reason is that it comes with a new feature, Asset catalogs which organizes all your start images and app icons easily. It's a bit confusing in the very beginning but when you are used to it, all your assets will be more organized.
