无法在iOS中设置标签颜色

Question

我有一个包含两个单元格的tableview。现在这些单元格包含标签，我想更改这些标签的颜色。

我的代码：

    - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
 static NSString *CellIdentifier = @"CheckerCell";
CustomCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.titleLabel.text = [titleArray objectAtIndex:indexPath.row];
cell.subTitleLabel.text=[subTitleArray objectAtIndex:indexPath.row];

     if (indexPath.row == 0) {
            cell.textLabel.textColor = [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
        }
        else if(indexPath.row == 1)
        {
            cell.textLabel.textColor = [UIColor colorWithRed:167/255.0 green:19/255.0 blue:43/255.0 alpha:1.0];
        }
    }

我在这里缺少什么？此代码也在基类中。这有关系吗？

请指导。

Answer 1

您应该首先创建您的单元格：

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

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

 if( !cell ) {

     cell = [[UITableViewCell alloc] init];
 if (indexPath.row == 0) {
        cell.textLabel.textColor = [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
    }
    else if(indexPath.row == 1)
    {
        cell.textLabel.textColor = [UIColor colorWithRed:167/255.0 green:19/255.0 blue:43/255.0 alpha:1.0];
    }
   }
}

同时结帐other functions也可以将单元格出列，并在此处查看最符合您需求的内容。

修改

    - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
     static NSString *CellIdentifier = @"CheckerCell";
     CustomCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

     // See this missing piece of code to create a cell
     if( !cell ) {

             cell = [[[NSBundle mainBundle] loadNibNamed:@"SomeTableViewCellDesignedFromXIB" owner:nil options:nil] objectAtIndex:0]; 
     }
     // See this missing piece of code 

     cell.titleLabel.text = [titleArray objectAtIndex:indexPath.row];
     cell.subTitleLabel.text=[subTitleArray objectAtIndex:indexPath.row];

     if (indexPath.row == 0) {
            cell.textLabel.textColor = [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
        }
        else if(indexPath.row == 1)
        {
            cell.textLabel.textColor = [UIColor colorWithRed:167/255.0 green:19/255.0 blue:43/255.0 alpha:1.0];
        }
    }

Answer 2

试试这个

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }
    if (indexPath.row == 0) {
        cell.textLabel.textColor = [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
    }
    else if(indexPath.row == 1)
    {
       cell.textLabel.textColor = [UIColor colorWithRed:167/255.0 green:19/255.0 blue:43/255.0 alpha:1.0];
    }

    cell.textLabel.text = @"your text here";


    return cell;
}

Answer 3

您不是首先创建单元格，您需要这样做才能设置颜色

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString static * identifiderPlain = @"CellPlain";

    UITableViewCell * cell;


    cell = [tableView dequeueReusableCellWithIdentifier:identifiderPlain];
    if(!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifiderPlain];
    }

    if (indexPath.row == 0) {
        cell.textLabel.textColor = [UIColor colorWithRed:(78.0f/255.0f) green:(157.0f/255.0f) blue:(19.0f/255.0f) alpha:1.0f];
    }
    else if(indexPath.row == 1)
    {
        cell.textLabel.textColor = [UIColor colorWithRed:(167.0f/255.0f) green:(19.0f/255.0f) blue:(43.0f/255.0f) alpha:1.0f];
    }

    return cell;
}

Answer 4

使用此

cell.textLabel.backgroundColor =  [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
