如何获取主包中子文件夹的路径? [英] How to get path to a subfolder in main bundle?

问题描述

我有一个项目，我要从 Obj-C 迁移到 Swift 3.0(我是 Swift 的菜鸟).

I have a project which I am migrating from Obj-C to Swift 3.0 (and I am quite a noob in Swift).

如何翻译这一行?

NSString *folder = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myfolder"];

我设法获得了资源路径:

I managed to get resource path:

let resoursePath = Bundle.main.resoursePath;

但是如何获取名为myfolder"的子文件夹的路径?我需要获取子文件夹的路径，而不是其中文件的路径.

But how do I get path to a subfolder named "myfolder"? I need to get a path the subfolder, not path to the files inside it.

推荐答案

在Swift-3中制作URL，并调用appendingPathComponent:

In Swift-3 make URL, and call appendingPathComponent:

let resourcePath = Bundle.main.resourcePath
let subdir = URL(fileURLWithPath:resourcePath!).appendingPathComponent("sub").path

或者干脆

let subdir = Bundle.main.resourceURL!.appendingPathComponent("sub").path
