if (ISIPAD)

    {
        
        [[NSOperationQueue mainQueue] addOperationWithBlock:^{
            

// UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
// m_pPopoverController= popover;
// [m_pPopoverController presentPopoverFromRect:CGRectMake(0, 0, 500, 500) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
// imagePicker.view.transform = CGAffineTransformMakeRotation(M_PI*3/2);

            [self presentViewController:imagePicker animated:YES completion:nil];

        }];
