内存泄漏_ContiguousArrayStorage？

Question

我是swift的新手.我正在运行内存泄漏的仪器工具.我发现了泄漏 "_ContiguousArrayStorage<String>"

它导致下面部分代码

let myData = NSData(data: request.value!)
let buffer = Array(UnsafeBufferPointer(start: UnsafePointer<CUnsignedChar>(myData.bytes), count: myData.length))

谁能帮我吗？.

上面的代码有什么问题吗？

编辑:添加更多代码.

let myData = NSData(data: request.value!)
var buffer = Array(UnsafeBufferPointer(start: UnsafePointer<CUnsignedChar>(myData.bytes), count: myData.length))

let responseArray: [CUnsignedChar] = Array(buffer)

let responseValue = BluetoothCommunicationManager.sharedInstance.parseData(responseArray,length: myData.length).0

let responseName = BluetoothCommunicationManager.sharedInstance.parseData(responseArray,length: myData.length).1

NSNotificationCenter.defaultCenter().postNotificationName(responseName, object: request, userInfo: responseValue as [NSObject : AnyObject])

singleton类的parseData方法返回NSMutableDictionary.

func parseData(responseData: [CUnsignedChar]) -> NSMutableDictionary
{
        let infoDictionary = NSMutableDictionary()
        let subIndexValue = Int(responseData[5])
        infoDictionary.setValue(subIndexValue, forKey: KEY_SUB_INDEX)
        return responseData
}

提前致谢.

看起来您正在尝试将 转换NSData为 的数组CUnsignedChar。您不需要使用UnsafeBufferPointer或UnsafePointer执行该转换。我怀疑您使用不安全指针是内存泄漏的根本原因。

Data您可以通过向数组传递一个对象而不是对象来创建数组NSData。试试这个：

let myData = NSData(data: request.value!) as Data
let responseArray = [CUnsignedChar](myData)

let responseValue = BluetoothCommunicationManager.sharedInstance.parseData(responseArray, length: responseArray.count).0

let responseName = BluetoothCommunicationManager.sharedInstance.parseData(responseArray, length: responseArray.count).1
