[UIView hash]: message sent to deallocated instance 0x6eef8a0 error

i am trying to jump to one viewControllers view from another viewContro开发者_StackOverflow社区llers view and during this phase im getting a crash on the device. I have my NSZombieEnabled and it is giving a error message as [UIView hash]: message sent to deallocated instance 0x6eef8a0

Can anyone throw some light on this please..... Thankyou

can you tell , when this exception occurs? I mean when it "jump" (push or present) the controller from A to B, or when it return back from controller B to A.?
