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

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

“Setting the background color on UITableViewheaderfooterView has been
deprecated. Please use contentView.backgroundColor instead.”

这里是加载我的自定义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;

}

解决方法

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.这是Apple根据this链接的首选方法.
