touches in landscape and portrait orientations

Question

Hi all,

i am developing a game for iPad, on Portrait and landscape orientations.

i am taking touches on four corners of the screen, touches is working properly on landscape mode, where as in Portrait mode actual problem, touches working on top corners but bottom corners touches is not working.

i think in portrait mode the view frame size is 748X1024 , but when i prints the frame size it is showing 1024X748.

How to solve this, need touches on four corners in landscape and portrait modes.

thank you
