字幕没有出现UITableView单元格

Question

I am new to app designing and Objective-C. I am writing a simple food app that has some food stored in an array with details of the food, food name, cook time and the file name which leads to a picture.

I am trying to get a subtitle to work but it isn't showing up. I've read various other posts and have tried to implement some of the answers but none have worked.

This is my code if there is anything obviously incorrect please let me know. Thank you.

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *CellIdentifier = @"FoodCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    if (cell == nil){
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }

    Food *current = [foodArray objectAtIndex:indexPath.row];


    [cell.textLabel setText:[current name]];
    [[cell detailTextLabel] setText:@[current cookTime]];
    cell.imageView.image = [UIImage imageNamed:[current fileName]];

    return cell;
}

Answer 1

Replace

[[cell detailTextLabel] setText:@[current cookTime]];

with

[[cell detailTextLabel] setText:[current cookTime]];

Note that this assumes cookTime is an NSString . If it is something else, like an integer representing minutes, you would do something like this:

[[cell detailTextLabel] setText:[NSString stringWithFormat:@"%d minutes", [current cookTime]]];

Additionally, you may find it easier to use this format:

cell.detailTextLabel.text = [NSString stringWithFormat:@"%d minutes", [current cookTime]];

Answer 2

Try to replace:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

with:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

Answer 3

试着用

cell.detailTextLabel.text = [current cookTime];
