Receiving side at a MultiPeer Connectivity data stream always returns Stream.Event.hasBytesAvailable Swift4












0














Well I can start streaming data in peer to peer connection. I get first bunch of data without problem and use it.



The problem is only



    case Stream.Event.hasBytesAvailable:


is firing at receiver side so I can not know if received data is consumed or not at sender side.



Besides,



      self.outputStream?.streamStatus.rawValue


returns open.



Receiver continues receiving new data which is piling up in receivedData.
After every



      let writtenData = data.withUnsafeBytes { self.outputStream?.write($0, maxLength: data.count) } 


writtenData have been never 0 or -1 by the way. It is always a value seems to be right amount we are writing.



we are suppose to use data and reset receivedData and wait in sender till receiver side ready.



It feels receiver should inform sender that data is consumed and ready for more in streaming but I could not find how to do it till now.



  var receivedData = NSMutableData()

func stream(_ aStream: Stream, handle eventCode: Stream.Event){

switch(eventCode){

case Stream.Event.hasBytesAvailable:

let input = aStream as! InputStream
var buffer = [UInt8](repeating: 0, count: 2048)
let len = input.read(&buffer, maxLength: buffer.count)

receivedData.append(buffer, length: len)


case Stream.Event.endEncountered:

case Stream.Event.hasSpaceAvailable:

case Stream.Event.openCompleted:

case Stream.Event.errorOccurred:

default:

show(text: "default")

}

}
