My game doesn't work correctly for IOS

Hi,
I’m newbie and i’ve done my game. It work correctly in android and WP, but in IOS it doesn’t
screen stutters, i think physics, touch all wrong and fps is about 30
i don’t know how to fix. Please help me!
and sorry about my english

Don’t know if it’s the case anymore, but unless you set Application.targetFramerate = 60 it won’t run at 60fps.

oh i fixed it…thanks anyway
