    【解决方案1】:

    这是一个使用 UIActionSheet 在 UITextView 中显示弹出菜单以响应附件上的 longPress 的示例。

    - (void)attachmentActionSheet:(UITextView *)textView range:(NSRange)range {
    
        // get the rect for the selected attachment (if its a big image with top not visible the action sheet
        // will be positioned above the top limit of the UITextView
        // Need to add code to adjust for this.
        CGRect attachmentRect = [self frameOfTextRange:range inTextView:textView];
    
          _attachmentMenuSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                               delegate:self
                                                      cancelButtonTitle:@"Cancel"
                                                 destructiveButtonTitle:nil
                                                      otherButtonTitles:@"Copy Image", @"Save to Camera Roll", @"Open in Viewer", nil];
    
        // Show the sheet
        [_attachmentMenuSheet showFromRect:attachmentRect inView:textView animated:YES];
    }
    
    - (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
        if (actionSheet == _attachmentMenuSheet) {
            //FLOG(@"Button %d", buttonIndex);
            switch (buttonIndex) {
    
                case 0:
                    //FLOG(@" Copy Image");
                    [self copyImageToPasteBoard:[_attachment image]];
                    break;
    
                case 1:
                    //FLOG(@"  Save to Camera Roll");
                    [self saveToCameraRoll:[_attachment image]];
                    break;
    
                case 2:
                    //FLOG(@"  Open in Viewer");
                    [self browseImage:[_attachment image]];
                    break;
    
                default:
                    break;
            }
        }
    }
    

    这就是它在 iPad 和 iPhone (iOS7) 上的样子
