如何从特定组加载图像?
在Xcode4中，我使用组来对我的东西进行分组，例如，对于各种图像，我有一个像树的树状层次结构.有趣的是，我可以直接访问图像而无需指定组.
In Xcode4, I use groups for grouping my stuff, for example I have a tree like group hierarchy for my various images. The interesting part is that I can access an image directly without specifying a group.
UIImage *img = [UIImage imageWithName:@"image1.png"];
我有两个问题.首先，如何定义所有需要的图像所在的组的具体路径(例如，对于"Img/Enemy/"组树)?第二，如何遍历该组路径以加载该组中的所有图像?恕我直言，组与捆绑包有关，但我发现它们非常令人困惑:(
I have two questions. First, how to define concrete path of groups where resides all needed images (for example for the group tree "Img/Enemy/")? And a second, how to iterate through that group path to load all the images from that group? IMHO groups are related to bundles but I found them very confusing :(
使用组时，实际上并没有创建文件夹，因此在构建应用程序时，所有内容都放在捆绑包的根目录中.这就是为什么您无需指定组名即可访问它们的原因.如果要使用文件夹，则可以在Finder中创建文件夹并将其添加到项目中(请确保选中为任何添加的文件夹创建文件夹引用"！).
When you use groups, you are not actually creating folders, so when you build your app everything is put at the root of the bundle. This is why you can access them without specifying the group name. If you want to use folders, you can create folders in Finder and add them to the project (make sure to check "create folder references for any added folders"!).
