Question

我正在尝试传递我创建的uitableviewcell中的文本标签，但我不确定执行此操作所需的参数。

我有一个NSObject，其方法有一个NSString对象作为参数，这也是我想从我的uitableviewcell标签传递信息的地方......

我有#imported .h文件并在视图tableViews：didSelectRowAtIndexPath方法中设置对象但是我不知道如何将文本从标签传递给我，这是我尝试过但我有兼容性警告..

   - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {        
        //initalize object to hold search parameters
        VehicleSearchObject *vehicleSearchObject = [[VehicleSearchObject alloc] init];


        [self.navigationController popViewControllerAnimated:YES]; //pops current view from the navigatoin stack

        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

        //--- this if block allows only one cell selection at a time and is passing the text in the cells label back to the object
        if (oldCheckedData == nil) { // No selection made yet
            oldCheckedData = indexPath;
            [cell setAccessoryType:UITableViewCellAccessoryCheckmark];
            [vehicleSearchObject GetManufacturers:[[cell textLabel] objectAtIndex:[indexPath row]] // This is where I try to pass the text back but not sure how to do it..

        }
        else {
            UITableViewCell *formerSelectedcell = [tableView cellForRowAtIndexPath:oldCheckedData]; // finding the already selected cell
            [formerSelectedcell setAccessoryType:UITableViewCellAccessoryNone];

            [cell setAccessoryType:UITableViewCellAccessoryCheckmark]; // 'select' the new cell
            oldCheckedData=indexPath;
        }   
    }

Answer 1

您只需执行以下操作即可引用单元格标签文本：

cell.textLabel.text

即。

[vehicleSearchObject GetManufacturers:cell.textLabel.text];

Answer 2

你必须这样做。

[vehicleSearchObject GetManufacturers:cell.textLabel.text];

Answer 3

[[cell textLabel] setText:[vehicleSearchObject GetManufacturers:[[cell textLabel] text]];
