Question

尝试更改UITableViewCell文字UIColour（服装单元格）会使文字变为白色且看不见，而只有在触摸UITableViewCell时，我才会看到文字。为什么将UIColour设置为不是UITableViewCell的{{1}}不起作用？

blackColor

这样做的时候：

- (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;
}

它的工作..

Answer 1

您基本上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];

Answer 2

使用它你没有在每个参数后面添加.0f（float），你没有得到单元格文本颜色。

[UIColor colorWithRed:122.0f/255.0f green:181.0f/255.0f blue:196 .0f/255.0f alpha:1.0f];

更改TableView单元格颜色将不起作用
