iOS7中带有取消按钮的弹出框内的UIImagePickerController

Question

我在iPad中的popover中显示UIImagePickerController类型UIImagePickerControllerSourceTypePhotoLibrary。我初始化并呈现这样的popover：

popoverController = [[UIPopoverController alloc]
                               initWithContentViewController:imagePicker];
[popoverController presentPopoverFromRect:popoverRect
                                   inView:self.view
                 permittedArrowDirections:UIPopoverArrowDirectionUp
                                 animated:YES]

在iOS 7的popover顶部栏上显示“取消”按钮，直到“照片”标题。点击此按钮什么都不做，我找不到处理它的方法，如何管理点击事件以解除弹出窗口，或者只是删除这个“取消”按钮？

您需要添加以下内容：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{

//DO WHATEVER WHEN YOU PRESS CANCEL BUTTON (PROBABLY DISMISSING THE POPOVER
[picker dismissViewControllerAnimated:YES completion:NULL];

}
