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

Question

我创建了一个自定义的 UITableViewHeaderFooterView 并成功地从 nib 加载到我的 UITableView 但总是收到此消息

"Setting the background color on UITableViewHeaderFooterView has been deprecated. Please use contentView.backgroundColor instead."

这里是加载自定义 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 nib 的页脚 View 中设置了“背景颜色”属性？如果是这样，请将其设置为“默认”。

你也可以考虑做

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

并且根本不设置 backgroundColor。根据 this，这是 Apple 的首选方法。链接。
