Instance Method


Open the flow, indicating to the system that the caller is ready to start receiving and sending data for the flow.


- (void)openWithLocalEndpoint:(NWHostEndpoint *)localEndpoint completionHandler:(void (^)(NSError *error))completionHandler;



An NWHostEndpoint object containing the port and address to set as the local port and local address of the socket associated with the flow.


A block that will be executed when the system is ready to handle the flow. If an error occurs while the flow is being opened then the error parameter will be set to a non-nil NSError object. See NEAppProxyFlowError below for a list of possible error codes. If the flow is opened successfully then the error parameter will be set to nil.


NEAppProxyFlow objects are received by the App Proxy Provider in an unopened state. The App Proxy Provider should take whatever steps are necessary to be ready to handle the flow’s data, and then call this method.
