Remarks

Callbacks to the MCSessionDelegate object are likely to be made on background threads. Application developers who wish to update the display must use, for instance, InvokeOnMainThread(Selector, NSObject).

Properties

Name	Description
Handle	Handle (pointer) to the unmanaged object representation. (Inherited from INativeObject)

Methods

Name	Description
DidChangeState(MCSession, MCPeerID, MCSessionState)	Indicates that the `session` has transitioned to the new `state`.
DidFinishReceivingResource(MCSession, String, MCPeerID, NSUrl, NSError)	Indicates that the transfer of `resourceName` has completed.
DidReceiveCertificate(MCSession, SecCertificate[], MCPeerID, Action<Boolean>)	Indicates `peerID` wishes to join the `session`. `certificateHandler` must be called.
DidReceiveData(MCSession, NSData, MCPeerID)	Indicates the arrival of `data`.
DidReceiveStream(MCSession, NSInputStream, String, MCPeerID)	Indicates the arrival of `stream`.
DidStartReceivingResource(MCSession, String, MCPeerID, NSProgress)	Indicates that `resourceName` has begun to arrive.

Extension Methods

Name	Description
DidReceiveCertificate(IMCSessionDelegate, MCSession, SecCertificate[], MCPeerID, Action<Boolean>)	Indicates `peerID` wishes to join the `session`. `certificateHandler` must be called.
GetHandle(INativeObject)
