ios - CFNetwork unexpectedly closes http connection -


i facing strange issue cfnetwork on ios simulator , on ios device.

i sending http requests remote server. sometimes, works correctly. cfnetwork opens socket remote server, sends http request in 1 packet , sends fin packet (after 1ms).

i don't see issue on mac os x, run similar code.

stream created cfreadstreamcreateforstreamedhttprequest() , put cfrunloop. if issue occurs, run-loop reports kcfstreameventopencompleted , subsequently reports kcfstreameventerroroccurred enotconn error.

it seems code behaves more stable if call:

cfwritestreamsetclient(stream, kcfstreameventnone, null, null);

before:

cfwritestreamunschedulefromrunloop(stream, ...);

it seems setting of empty client before stream unscheduled resolved hardly explain issues cfnetwork. maybe streams generating events after should cleaned up.
