sorry, i wrong definition path for my PDF file, now it's OK

second question is: how to play multimedia content such as audio and video..??

i so sorry to many ask

- thanks for fast reply

i never coding for multimedia.
there are some SDKs, i heard:
--AudioToolbox framework
--AVFoundation framework
--MediaPlayer framework
it seems you need add some frameworks

No, i mean how SDK recognise that video or audio attachment

like android PDF SDK, if open video or audio attachment they will call function onOpenMovie(String file_name) or onOpenSound(int[] paras, String file_name)

what iOS call function like that..??
