ios - ShouldAutoplay on MoviePlayerController -

-

i new developer, therefore i'm still learning , know i'm doing things wrong. have segmented control object in when user presses 1 of segments, goes play video. have setup press segment, have press play button video play. want cut out play button , have play automatically. i'm having trouble. found shouldautoplay option when use , cut out button, won't take me video @ all. i'm sure i'm not using shouldautoplay option correctly. hoping or @ least point in right direction. 

- (ibaction)playmovie:(id)sender;  {     nsbundle *bundle = [nsbundle mainbundle];     nsstring *moviepath = [bundle pathforresource:@"mytestimony" oftype:@"m4v"];     nsurl *movieurl = [[nsurl fileurlwithpath:moviepath] retain];     mpmovieplayercontroller *themovie = [[mpmovieplayercontroller alloc] initwithcontenturl:movieurl];     themovie.shouldautoplay = yes;     themovie.scalingmode = mpmoviescalingmodeaspectfill;     [themovie autorelease];     mpmovieplayerviewcontroller *movieplayer = [[mpmovieplayerviewcontroller alloc] initwithcontenturl:movieurl];     [self presentmovieplayerviewcontrolleranimated:movieplayer]; }

have tried [themovie play];?

update: noticed set shouldautoplay in themovie, presented instance of mpmovieplayerviewcontroller, movieplayer. that's why movie did not autoplay. should instead have:

[self presentmovieplayerviewcontrolleranimated:themovie];

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
