我有一个我创建的自定义 TableViewCell。每个单元格都有两个 UIlabels,我希望它们是不同的颜色。另外,我的 tableView 有一个部分,我想要不同的背景颜色和文本颜色。
现在,我无法使用我的 UILabel.textColor 更改文本颜色;虽然我确实让它与 cell.textLabel.textColor 一起使用。cell.background 颜色也不起作用。
如果我在底部的 switch 语句中执行此操作,我能够使单元格属性更改工作,但是单元格属性不会正确地去队列,因此当我向上和向下滚动时,随机单元格将变成红色背景上的白色文本。

static NSString *CellIdentifier = @"MyIdentifier";
UILabel* itemLabel;
UILabel* amountLabel;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
itemLabel = [[[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 220.0, 35.0)] autorelease];
itemLabel.tag = ITEMLABEL_TAG;
itemLabel.font = [UIFont systemFontOfSize:14.0];
itemLabel.textAlignment = UITextAlignmentLeft;
itemLabel.autoresizingMask = UIViewAutoresizingNone;
itemLabel.backgroundColor = [UIColor clearColor];
itemLabel.textColor = [UIColor blueColor]; //This doesn't work
if (indexPath.section == 4)
{
cell.textLabel.textColor = [UIColor whiteColor]; //This works
cell.backgroundColor = [UIColor redColor]; //This doesn't work
}
[cell.contentView addSubview:itemLabel];
cell.backgroundColor = [UIColor whiteColor];
amountLabel = [[[UILabel alloc]initWithFrame:CGRectMake(225.0, 0.0, 55.0, 35.0)] autorelease];
