ios4 - Realtime time message in iPhone SDK -

-

i'm finding way realtime messaging in iphone sdk. iphone safari doesn't support web socket. apple push notification working on application close. want make chat program real time. there other way except web socket ?

it's next version of ios (4.2) add websockets support. ios 4.2 should out month.

you might looked @ socket.io if control server side too. socket.io javascript library client , server uses best communication transport both ends support starting native websockets, flash based websockets fallback, various long-poll/comet options. api on client , server sides normal websockets api regardless of underlying transport used. allow use websockets protocol when available , fall still works when don't have websockets (without requiring use different api).
