在ipad或iphone中打开UIImagePicker使用Bellow代码： -

#define isiPhone（UI_USER_INTERFACE_IDIOM（）== 0）？TRUE：FALSE

 UIImagePickerController *pckrImage = [[UIImagePickerController alloc] init];
    pckrImage.delegate = self;
if (isiPhone) {
                if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary])
                {
                    pckrImage.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                    [self presentModalViewController:pckrImage animated:YES];
                }
                else {

                }
            }
            else
            {
                popover = [[UIPopoverController alloc]initWithContentViewController:pckrImage];
                [popover presentPopoverFromRect:CGRectMake(450.0f, 825.0f, 10.0f, 10.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];


            }

解雇时选择UIImaegPicker： -

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
 if(isiPhone)
    {
        [self dismissViewControllerAnimated:YES completion:^{

        }];
    }
    else
    {
        [popover dismissPopoverAnimated:YES];


    }

}

在iPad中，您必须使用它：

UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController: picker];

[popover presentPopoverFromBarButtonItem: item
                permittedArrowDirections: UIPopoverArrowDirectionAny
                                animated: YES];

或

[popover presentPopoverFromRect: CGRectMake(0, 0, 100, 100)
                         inView: self.view
       permittedArrowDirections: UIPopoverArrowDirectionAny
                       animated: YES];
