how can I make a popover and arrow with presentPopoverFromRect?

I don't understand how to define the (CGRect)rect in order to control the position of popover, and the position of the arrow.

For example, I have a 1004 x 768 view, how can I put the popover at lower right of the screen, and point the arrow at 700 (x) 1000 (y)?

Cgrectmake(700,1000,10,10) and uipopoverarrowdirectionleft sorry I'm on my iPad so I can't write the exact code but pass those in as the arguments for your presentpopoverfromrect method. The only thing is i think you're too far to the right to put a popover there unless I'm not understanding your question.
