获取位于 Assets.xcassets 的数据集中文件的路径 [英] Get path of a file in a data set located in Assets.xcassets

问题描述

我的 Assets.xcassets 中有一组音频文件:

I have a data set of audio files in my Assets.xcassets:

我正在尝试获取其中一个音频文件的路径，如下所示:

I'm trying to get the path of one of those audio files like this:

let path: String = Bundle.main.path(forResource: "acoustic_grand_piano/A4", ofType: "f32")!

但我得到一个EXC_BAD_INSTRUCTION.我试图在互联网上查看，但在数据集上找不到任何内容.

But I get a EXC_BAD_INSTRUCTION. I tried to look on the internet but I don't find anything on Data Sets.

如何获取这些文件之一的内容?

How can I get the content of one of these files?

谢谢！

推荐答案

试试这个:

• 手动将您的文件放入一个文件夹中，并命名为您想要的任何名称.
• 将.bundle"附加到文件夹以创建包.你会收到警告，接受它.恭喜，您刚刚创建了您的第一个捆绑包！:-)
• 手动将该文件夹拖到您的应用中.

• 使用以下代码获取您的文件....

• Manually put your files into a folder, named anything you want.
• Append ".bundle" to the folder to create a bundle. You'll get a warning, accept it. Congrats, you've just created your first bundle! :-)
• Manually drag that folder into your app.

• Get at your files by using the following code....

public func returnFile(_ named:String) -> String {
    let path: String = Bundle.main.path(forResource: "myAudioFiles", ofType: "bundle")! + "/" + name + ".f32"        
    do {
        return try String(contentsOfFile: path)
    }
    catch let error as NSError {
        return error.description
    }
}

现在，我的文件是 CIKernel 代码的文本文件.由于您的文件是音频文件，您可能需要将字符串返回更改为其他内容.

Now, my files are text files of CIKernel code. Since your's are audio files you may need to change the String return to something else.

就我而言，我使用的是框架，因为我希望与扩展程序和其他应用程序共享这些文件/图像.如果您在这样的设置中工作，这里是未更改的代码:

In my case I'm using a framework, as I wish to share these files/images with extensions and other apps. If you are working in such a set up, here's the unaltered code:

public func returnFile(_ resource:String, _ fileName:String, _ fileType:String) -> String {
    let identifier = "com.companyname.appname" // replace with framework bundle identifier
    let fileBundle = Bundle.init(identifier: identifier)
    let filePath = (fileBundle?.path(forResource: resource, ofType: "bundle"))! + "/" + fileName + "." + fileType
do {
    return try String(contentsOfFile: filePath)
}
catch let error as NSError {
    return error.description
}

}
