ios - 更改 TableView 单元格颜色将不起作用

Question

尝试更改 UITableViewCell 文本 UIColour(服装单元格)将使文本变成白色且看不见，而不是仅在触摸 UITableViewCell 时，我可以看到文字。 为什么将 UIColour 设置为不是 blackColor 的 UITableViewCell 将不起作用？

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

    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = 
     [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier 
                                          forIndexPath:indexPath];       
    if (!indexPath.row) {
        NSDictionary *dic= [[GlobalData sharedGlobals].categories 
                             objectAtIndex:indexPath.section];
        cell.textLabel.text = [dic objectForKey:@"title"]; // only top row showing
        cell.textLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" 
                                              size:22];
        cell.textLabel.textColor = [UIColor colorWithRed:177 
                                                   green:218 
                                                    blue:229 
                                                   alpha:1];
        //cell.textLabel.backgroundColor = [UIColor colorWithRed:218 
                                                           green:241 
                                                            blue:245 
                                                           alpha:1];
    } else {
       NSMutableArray *typesOfSection = 
        [[GlobalData sharedGlobals].typesByCategories 
          objectAtIndex:indexPath.section];
        NSDictionary *type = [typesOfSection objectAtIndex:indexPath.row-1];
        NSString *titleOfType = [type objectForKey:@"title"];
        cell.textLabel.text = titleOfType;
        cell.textLabel.textColor = [UIColor colorWithRed:122 
                                                   green:181 
                                                    blue:196 
                                                   alpha:1];
        cell.textLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" 
                                              size:22];

        //cell.textLabel.text = @"check";
        cell.accessoryView = nil;
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

    return cell;
}

当这样做的时候:

cell.textLabel.textColor = [UIColor redColor];

它的工作..

Answer 1

您基本上是将单元格的文本颜色设置为白色。 RGB 值应介于 0.0 和 1.0 之间。

试试这个

[UIColor colorWithRed:122.0/255.0 green:181.0/255.0 blue:196.0/255.0 alpha:1.0];
