定位到用戶文檔目錄

  let manager = FileManager.default
  let url = manager.urls(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask).first as NSURL!

創(chuàng)建文件

 func createFile(name:String, baseUrl:NSURL){
        let manager = FileManager.default
        let fileUrlPath = baseUrl.appendingPathComponent(name)
        
        let exist = manager.fileExists(atPath: (fileUrlPath?.path)!)
        if !exist {
            manager.createFile(atPath:(fileUrlPath?.path)!, contents: nil, attributes: nil)
        }
    }

創(chuàng)建文件夾

// 創(chuàng)建文件夾
    func createFolder(name:String, baseUrl:NSURL) {
        let manager = FileManager.default
        let folderUrlPath = baseUrl.appendingPathComponent(name)
        
        let exist = manager.fileExists(atPath: (folderUrlPath?.path)!)
        if !exist { // 判斷是否已存在此文件夾,若不存在則創(chuàng)建文件夾
            // withIntermediateDirectories為ture表示路徑中間如果有不存在的文件夾都會創(chuàng)建
            try? manager.createDirectory(at: folderUrlPath!, withIntermediateDirectories: true, attributes: nil)
        }
    }

使用方法

（1）創(chuàng)建文件
self.createFile(name: "test.txt", baseUrl: url as NSURL!)
(2)創(chuàng)建文件夾
self.createFolder(name: "folder", baseUrl: url as NSURL!)

運行結(jié)果
