UItableView：无法更改单元格的颜色(UItableView: unable to change color of a cell)

我是iPhone编程的新手，我无法更改表格视图单元格的背景

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; if((indexPath.row%2)!=0) { [cell setBackgroundColor:[UIColor clearColor]]; [cell setBackgroundColor:[UIColor redColor]]; //[cell ]; } else { [cell setBackgroundColor:[UIColor whiteColor]]; } } // Configure the cell... [cell setText:[menuItems objectAtIndex:indexPath.row]]; return cell;

}

请帮我理解为什么??

好的，得到了​​答案

- (void)tableView: (UITableView*)tableView willDisplayCell: (UITableViewCell*)cell forRowAtIndexPath: (NSIndexPath*)indexPath { cell.backgroundColor = indexPath.row % 2 ? [UIColor colorWithRed: 0.0 green: 0.0 blue: 1.0 alpha: 1.0] : [UIColor whiteColor]; cell.textLabel.backgroundColor = [UIColor clearColor]; cell.detailTextLabel.backgroundColor = [UIColor clearColor]; }

Ok got the answer

- (void)tableView: (UITableView*)tableView willDisplayCell: (UITableViewCell*)cell forRowAtIndexPath: (NSIndexPath*)indexPath { cell.backgroundColor = indexPath.row % 2 ? [UIColor colorWithRed: 0.0 green: 0.0 blue: 1.0 alpha: 1.0] : [UIColor whiteColor]; cell.textLabel.backgroundColor = [UIColor clearColor]; cell.detailTextLabel.backgroundColor = [UIColor clearColor]; }
