如何获得uitableviewcell的detailtextlabel的默认CGRECT尺寸？

Question

我们希望添加一个UIextLabel来代替UITableViewCell的UITableViewCellStyleSubtitle的默认detailTextLabel。我可以显示UITextLabel，但是问题是我无法像对待detailTextLabel一样对齐它。我尝试过的以下代码是这样：

switch (indexPath.row) {
            case 1:{
                cell.accessoryType = UITableViewCellAccessoryNone;
                cell.detailTextLabel.numberOfLines = 1;
                //cell.detailTextLabel.text = @"Enter your display name";
                //self.displayNameTextField = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
                self.displayNameTextField = [[UITextField alloc] initWithFrame:CGRectMake(cell.detailTextLabel.frame.origin.x, cell.detailTextLabel.frame.origin.y, cell.detailTextLabel.frame.size.height, cell.detailTextLabel.frame.size.width)];
                self.displayNameTextField.placeholder = @"Enter your display name";
                self.displayNameTextField.autocorrectionType = UITextAutocorrectionTypeNo;
                [self.displayNameTextField setClearButtonMode:UITextFieldViewModeWhileEditing];
                [cell addSubview:self.displayNameTextField];

                break;
            }
            default:
                break;
        }

您的代码中的一个小更正。您可以使用自己的代码进行一些更改。

尝试一下。它将起作用。

 switch (indexPath.row){
        case 1:{
            cell.accessoryType = UITableViewCellAccessoryNone;
            cell.detailTextLabel.numberOfLines = 1;
            UITextField *displayNameTextField = [[UITextField alloc] initWithFrame:cell.detailTextLabel.frame];
            displayNameTextField.placeholder = @"Enter your display name";
            displayNameTextField.autocorrectionType = UITextAutocorrectionTypeNo;
            [displayNameTextField setClearButtonMode:UITextFieldViewModeWhileEditing];
            [cell addSubview:displayNameTextField];
            break;
        }
        default:
            break;
    }
