如何在Array（或某些数据结构？）中获取Assets.xcassets文件名？ [英] How to get Assets.xcassets file names in an Array (or some data structure?)

问题描述

我正在尝试使用Swift迭代我放入Assets文件夹的图像。我想迭代它们并稍后将它们插入到 .nib 文件中，但到目前为止我找不到如何得到类似的东西：

I'm trying to use Swift to iterate over the images I have put into my Assets folder. I'd like to iterate over them and insert them into a .nib file later, but so far I cannot find how to get something like:

让assetArray = [image1.gif，image2.gif，...]

这可能吗？我一直在玩 NSBundle.mainBundle（），但在这上面找不到任何东西。请告诉我。谢谢！

Is this possible? I've been playing with NSBundle.mainBundle() but couldn't find anything on this. Please let me know. Thanks!

推荐答案

Assets.xcassets不是文件夹，而是包含使用Assets.car作为其文件名的所有图像的存档。

Assets.xcassets is not a folder but an archive containing all the images using Assets.car as its filename.

如果你真的想读取资产文件，那么你需要使用一些可以提取文件内容的库，如下所示 one 。

If you really want to read the assets file then you need to use some library that can extract the contents of the file like this one.

或者您可以在项目中创建一个包并拖动你在那里的所有图像。就我而言，我的项目中有Images.bundle。要获取文件名，您可以执行以下操作：

Or you can create a bundle in your project and drag all the images you have there. In my case, I have Images.bundle in my project. To get the filenames you can do the following:

let fileManager = NSFileManager.defaultManager()
let bundleURL = NSBundle.mainBundle().bundleURL
let assetURL = bundleURL.URLByAppendingPathComponent("Images.bundle")
let contents = try! fileManager.contentsOfDirectoryAtURL(assetURL, includingPropertiesForKeys: [NSURLNameKey, NSURLIsDirectoryKey], options: .SkipsHiddenFiles)

for item in contents
{
  print(item.lastPathComponent)
}

SWIFT 3版本：

SWIFT 3 Version:

let fileManager = FileManager.default
let bundleURL = Bundle.main.bundleURL
let assetURL = bundleURL.appendingPathComponent("Images.bundle")
let contents = try! fileManager.contentsOfDirectory(at: assetURL, includingPropertiesForKeys: [URLResourceKey.nameKey, URLResourceKey.isDirectoryKey], options: .skipsHiddenFiles)

for item in contents
{
    print(item.lastPathComponent)
}
