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];

所述UIActionSheet文档指出的showFromRect:inView:animated:方法:

在弹出窗口中显示操作表,其中箭头指向视图的指定矩形(在我们的示例中为详细信息公开按钮).弹出窗口不与指定的矩形重叠.
