推荐答案

网络上的数据总是以字节为单位，无论是否有任何平台。在发送之前，NSData最终会转换为字节数据它通过网络..在更高级别，您的数据应该是NSData格式，但在较低级别它的字节数。所以在ios中它将是数据字节（如果您使用NSInputstream上传数据）或NSData（最终将再次转换为字节并通过网络发送）

The data on a network always flows in Bytes irrespective of any platform.. NSData will finally be converted to bytes data before sending it over network.. On higher level your data should be in NSData format but on lower level its on Bytes.. So in ios it will be either Bytes of Data (if you are using NSInputstream to upload data) or NSData (which will finally converted to Bytes again and sent over the Network)
