取得路径下的paths，判断是文件还是文件夹

查看Bundle下Doc目录下的文件

class ViewController: UIViewController {
    override func touchesBegan(_ touches: Set, with event: UIEvent?) {
        let basePath = Bundle.main.bundlePath+"/Doc"
        let vc = ListTVC()
        vc.fullPath = basePath
        navigationController?.pushViewController(vc, animated: true)
    }

FileModel.swift

import Foundation

struct FileModel {
    ///完整路径
    var path = ""
    ///是否文件夹
    var isDirectory = false
    
    init(_ path: String, isDirectory: Bool) {
        self.path = path
        self.isDirectory = isDirectory
    }
}

FileMgr.swift

let fileMgr = FileManager.default
    
/**
 let fm = FileMgr()
 fm.getSubWithPath(Bundle.main.bundlePath+"/Doc")
 */
class FileMgr {
}

extension FileMgr {
    
    func getSubWithPath(_ fullPath: String) -> [FileModel] {
        
        var result: [FileModel] = []
        
        if let contents = try? fileMgr.contentsOfDirectory(atPath: fullPath) {
            DebugLog(contents)
            for content in contents {
                var isDir = ObjCBool(false)
                let path = fullPath.appending("/")+content
                DebugLog(path)
                
                if fileMgr.fileExists(atPath: path, isDirectory: &isDir) {
                    //DebugLog(isDir.boolValue, path)
                    result.append(FileModel(path, isDirectory: isDir.boolValue))
                }
            }
        }
        
        return result
    }
}

展示文件/夹列表ListTVC.swift

import UIKit

class ListTVC: UITableViewController {

    var fullPath = ""
    var dataList: [FileModel] = []
    let fileMgr = FileMgr()
    
    override func viewDidLoad() {
        super.viewDidLoad()

        initView()
        initData()
    }

    fileprivate func initView() {
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
    }

    fileprivate func initData() {
        dataList = fileMgr.getSubWithPath(fullPath)
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return dataList.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)

        let model = dataList[indexPath.row]
        let text = (model.path as NSString).lastPathComponent
        cell.textLabel?.text = (model.isDirectory ? "" : "")+text

        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
        
        let model = dataList[indexPath.row]
        if model.isDirectory {
            let vc = ListTVC()
            vc.navigationItem.title = (model.path as NSString).lastPathComponent
            vc.fullPath = model.path
            navigationController?.pushViewController(vc, animated: true)
        } else {
            
        }
    }
}
