Answer 1

试试这个:

UIActionSheet *popupSheet = [[UIActionSheet alloc] initWithTitle:@"Title" 
                                                        delegate:self 
                                               cancelButtonTitle:@"Cancel" 
                                          destructiveButtonTitle:@"No Way !" 
                                               otherButtonTitles:nil];

popupSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
UIButton * disclosureButton = (UIButton *)cell.accessoryView;

[popupSheet showFromRect:disclosureButton.bounds inView:cell.accessoryView animated:YES];
[popupSheet release];

UIActionSheet docs声明 showFromRect:inView:animated: 方法:

displays the action sheet in a popover whose arrow points to the specified rectangle of the view (in our case the detail disclosure button). The popover does not overlap the specified rectangle.
