如何从.bin文件中快速读取数据

Question

我必须从.bin文件中读取数据。但是我没有找到任何文件或其他东西

我有一个bin文件，我将其复制到项目文件夹中。

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    //setSettings()
    let fileName = "MLM_FW_Ver1.3.4.bin"
    var filePath = ""

    // Fine documents directory on device
    let dirs : [String] = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.allDomainsMask, true)

    if dirs.count > 0 {
        let dir = dirs[0] //documents directory
        filePath = dir.appending("/" + fileName)
        print("Local path = \(filePath)")
    } else {
        print("Could not find local directory to store file")
        return
    }

    // Read file content. Example in Swift
    do {
        let contentFromFile = try NSString(contentsOfFile: filePath, encoding: String.Encoding.utf8.rawValue)
        print(contentFromFile)
    }
    catch let error as NSError {
        print("An error took place: \(error)")
    }


}

构建该项目并运行代码，然后我看到此错误；

Code = 260“由于没有这样的文件，因此无法打开文件“ MLM_FW_Ver1.3.4.bin”。” UserInfo = {NSFilePath = / var / mobile / Containers / Data / Application / DB021CBC-E3A9-4403-A360-1736ED4A691B / Documents / MLM_FW_Ver1.3.4.bin，NSUnderlyingError = 0x282e82100 {Error Domain = NSPOSIXErrorDomain Code = 2“没有此类文件或目录“}}
