ios - Swift 3 - FTP 上传

Question

我已将 Rebekka 触摸框架添加到我的 Swift 3 项目中，以便通过 FTP 上传文件。

我在 xCode 中使用了 swift 3 转换工具，但只剩下一个错误

Value of type 'NSMutableData' has no member 'count'

这是它发生的地方:

let bytes = self.inputData!.bytes.bindMemory(to: UInt8.self, capacity: self.inputData!.count)

完整功能:

override func streamEventEnd(_ aStream: Stream) -> (Bool, NSError?) {
    var offset = 0
    let bytes = self.inputData!.bytes.bindMemory(to: UInt8.self, capacity: self.inputData!.count)
    let totalBytes = CFIndex(self.inputData!.length)
    var parsedBytes = CFIndex(0)
    let entity = UnsafeMutablePointer<Unmanaged<CFDictionary>?>.allocate(capacity: 1)
    var resources = [ResourceItem]()
    repeat {
        parsedBytes = CFFTPCreateParsedResourceListing(nil, bytes.advancedBy(offset), totalBytes - offset, entity)
        if parsedBytes > 0 {
            let value = entity.pointee?.takeUnretainedValue()
            if let fptResource = value {
                resources.append(self.mapFTPResources(fptResource))
            }
            offset += parsedBytes
        }
    } while parsedBytes > 0
    self.resources = resources
    entity.deinitialize()
    return (true, nil)
}

有人知道 self.inputData!.count 的 swift 3 等价物吗？

我正在使用 Swift3。我在 Rebekka 框架的源代码中做了以下更改，特别是文件 ResourceListOperation.swift。 (注意:高级(by:..)，.length)。

fileprivate var inputData: NSMutableData?
var resources: [ResourceItem]?

override func streamEventEnd(_ aStream: Stream) -> (Bool, NSError?) {
    var offset = 0
    let bytes = self.inputData!.bytes.bindMemory(to: UInt8.self, capacity: self.inputData!.length)
    let totalBytes = CFIndex(self.inputData!.length)
    var parsedBytes = CFIndex(0)
    let entity = UnsafeMutablePointer<Unmanaged<CFDictionary>?>.allocate(capacity: 1)
    var resources = [ResourceItem]()
    repeat {
        parsedBytes = CFFTPCreateParsedResourceListing(nil, bytes.advanced(by: offset), totalBytes - offset, entity)
        if parsedBytes > 0 {
            let value = entity.pointee?.takeUnretainedValue()
            if let fptResource = value {
                resources.append(self.mapFTPResources(fptResource))
            }
            offset += parsedBytes
        }
    } while parsedBytes > 0
    self.resources = resources
    entity.deinitialize()
    return (true, nil)
}

这是我在我的应用程序中用于在导入 RebekkaTouch 框架后列出目录的内容:

    var configuration = SessionConfiguration()
    configuration.host = "<ip-address:followed-by-port>"
    configuration.username = "uname"
    configuration.password = "password"
    configuration.encoding = String.Encoding.utf8
    self.session = Session(configuration: configuration)
    self.session.list("/") {
        (resources, error) -> Void in
        print("List directory with result:\n\(String(describing: resources)), error: \(String(describing: error))\n\n")
    }
