问题解答

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];}]; }else if (ISIPHONE) {[self presentViewController:imagePicker animated:YES completion:nil]; }
