MCSession

A MCSession facilitates communication among all peers in a multipeer session.

To start a multipeer session with remote peers, a MCPeerID that represents the local peer needs to be supplied to the init method.

Once a peer is added to the session on both sides, the delegate callback -session:peer:didChangeState: will be called with MCSessionStateConnected state for the remote peer.

Data messages can be sent to a connected peer with the -sendData: toPeers:withMode:error: method.

The receiver of data messages will receive a delegate callback -session:didReceiveData:fromPeer:.

Resources referenced by NSURL (e.g. a file) can be sent to a connected peer with the -sendResourceAtURL:toPeer:withTimeout:completionHandler: method. The completionHandler will be called when the resource is fully received by the remote peer, or if an error occurred during transmission. The receiver of data messages will receive a delegate callbacks -session:didStartReceivingResourceWithName:fromPeer: withProgress: when it starts receiving the resource and -session: didFinishReceivingResourceWithName:fromPeer:atURL:withError: when the resource has been fully received.

A byte stream can be sent to a connected peer with the -startStreamWithName:toPeer:error: method. On success, an NSOutputStream object is returned, and can be used to send bytes to the remote peer once the stream is properly set up. The receiver of the byte stream will receive a delegate callback -session:didReceiveStream: withName:fromPeer:

Delegate calls occur on a private serial queue. If your app needs to perform an action on a particular run loop or operation queue, its delegate method should explicitly dispatch or schedule that work.

                                                                       java.lang.String resourceName,
                                                                       MCPeerID peerID,

Send a resource referenced by an NSURL to a remote peer. The resource can be a file or an HTTP document. The completionHandler is called when the resource is received by the remote peer or if an error occurred. The remote peer will get a -session:didStartReceivingResourceWithName: fromPeer:withProgress callback when it starts receiving the resource and a -session:didFinishReceivingResourceWithName:fromPeer:atURL:withError: when the resource has been fully received.

The primary mechanism for observing progress of the send should be to create an NSProgress using +progressWithTotalUnitCount, -becomeCurrentWithPendingUnitCount:, invoking this method, then calling -resignCurrent. This is described in the NSProgress documentation. Alternatively, if you wish to observe the progress directly instead of incorporating it into a larger operation, you may observe the NSProgress returned from this method.

public NSOutputStream startStreamWithNameToPeerError(java.lang.String streamName,
