The class reference documentation says:

Return Value

YES if the options menu was displayed or NO if it was not. The options menu may not be displayed in cases where there are no appropriate items to include in the menu.

I think your %3F1340297029 suffix on currentPDFPath may be preventing a UTI match.

Check the UTI property of docController and set to kUTTypePDF if it is nil.

Thanks for replying.My this problem is resolved. Now "BOOL success" is returning 1. But I am not able to open this pdf in iBook. – Priyanka Chhetri Jul 02 '12 at 16:19
Now the error is "*** Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible." – Priyanka Chhetri Jul 02 '12 at 16:21

Your crashing issue is probably because your docController has already been released. You'll need to retain it and then autorelease it later. Have a look here:

I modified your code a bit, not it is working for me, I am using ARC, so you have to change it to fit your non-ARC code.

BOOL success = [self.documentInteractionController presentOpenInMenuFromRect:rect inView:self.view animated:YES];

                if (success == NO) {
                    NSLog(@"No application was found");
                } else {

                    NSLog(@"Applications were found");
                }

The BOOL is either returning YES or NO, YES it the line behind the = is TRUE and NO if the line is FALSE.
