从nib加载时,UITableViewHeaderFooterView无法更改自定义背景

Question

我已经创建了一个自定义的UITableViewHeaderFooterView并成功从nib加载到我的UITableView中,但始终收到此消息

"不推荐在UITableViewHeaderFooterView上设置背景颜色.请改用contentView.backgroundColor."

这里加载我的自定义UITableViewHeaderFooterView的代码:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
   KTHeaderFooterViewIphone customHeaderIphone* = [[[NSBundle mainBundle] loadNibNamed:@"KTHeaderFooterViewIphone" owner:self options:nil] objectAtIndex:0];
    customHeaderIphone.tintColor = [UIColor whiteColor];  // this code worked, but the message above always show
    customHeaderIphone.contentView.backgroundColor = [UIColor redColor];  // this code doesn't work, nothing's happened
    customHeaderIphone.contentView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"customHeader.png"]];  // this code doesn't work too, I can't change custom background image
    return customHeaderIphone;

}

您是否在笔尖的页脚视图中设置了"背景颜色"属性？如果是这样,请将其设置为"默认".

你也可以考虑这样做

customHeaderIphone.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"customHeader"]];

而根本没有设置backgroundColor.根据此链接,这是Apple的首选方法.
