app store - Restore used to restore purchases for different accounts in ios app -

-

i had implemented restore button in our app causing issue if member created account our app , pays through appstore. if creates member in our app , restores purchase tapping restore button , putting in app id in fashion using 1 apple app id able have multiple platinum members buying once fo 1 single member , restoring multiple times diferent members.

this upcoming website , app have free/basic plan registers , upgradable 1 time/lifetime platinum plan. in ios app have received message apple in resolution center "to restore purchased in-app purchase products, appropriate provide "restore" button , initiate restore process when "restore" button tapped user."

now if member has upgraded 1 device , logging in ios device not basic member platinum member per our database , hence not see buy/upgrade platinum scene in our app.

basically can avoid rejection removing restore button. solution the above case

i have selected non-consumable purchase

is platinum membership associated specific login server? if so, on server, when process in-app purchase receipt , associated user account record receipt id. every time process receipt, check , see if user has claimed purchase first, , don't honor if it's repeat. replay attacks pretty classic ploy , defeated if purchase tied user login...

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
