// 1、获取沙盒根目录let homeDir = NSHomeDirectory() as String

// 2、获取 Documents 目录
let docDirs = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) as NSArray
let docDir = docDirs[0] as! String
print("[hybird]","docDirs",docDirs)
print("[hybird]","docDir",docDir)
// 3、获取 Caches 目录
let cachesDirs = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true) as NSArray

// 5、获取 tmp 目录

let tmpDir = NSTemporaryDirectory() as String

// 6、初始化 fileManager
let fileManager = FileManager.default

// 7、使用 fileManager 创建目录
let testDir = docDir + "/test"

fileManager.createFile(atPath: testFile1, contents: nil, attributes: nil)

// 9、使用 fileManager 获取目录下的文件名
var files = fileManager.subpaths(atPath: testDir)
print("[hybird]","files:",files ?? "")
// 10、使用 fileManager 删除文件
do {
    try fileManager.removeItem(atPath: testFile1)
