In iOS 7.0.4 I created a custom header with it's own XIB. Nothing mentioned here before worked. It had to be the subclass of the UITableViewHeaderFooterView to work with the dequeueReusableHeaderFooterViewWithIdentifier: and it seems that class is very stubborn regarding the background color. So finally I added an UIView (you could do it either with code or IB) with name customBackgroudView, and then set it's backgroundColor property. In layoutSubviews: I set that view's frame to bounds. It work with iOS 7 and gives no glitches.
// in MyTableHeaderView.xib drop an UIView at top of the first child of the owner
// first child becomes contentView
// in MyTableHeaderView.h
@property (nonatomic, weak) IBOutlet UIView * customBackgroundView;
// in MyTableHeaderView.m
-(void)layoutSubviews;
{
[super layoutSubviews];
self.customBackgroundView.frame = self.bounds;
}
// if you don't have XIB / use IB, put in the initializer:
-(id)initWithReuseIdentifier:(NSString *)reuseIdentifier
{
...
UIView * customBackgroundView = [[UIView alloc] init];
[self.contentView addSubview:customBackgroundView];
_customBackgroundView = customBackgroundView;
...
}
// in MyTableViewController.m
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
MyTableHeaderView * header = [self.tableView
dequeueReusableHeaderFooterViewWithIdentifier:@"MyTableHeaderView"];
header.customBackgroundView.backgroundColor = [UIColor redColor];
return header;
}

在UITableViewHeaderFooterView上设置背景色已弃用。请使用contentView。写成backgroundColor代替。
我通过控制台日志从Xcode得到消息
[TableView]设置背景色 UITableViewHeaderFooterView已弃用。请设置自定义 带有你想要的背景颜色的UIView到backgroundView 财产。
然后我只需要创建一个新的UIView并将其作为HeaderView的背景。 这不是一个很好的解决方案,但正如Xcode所说的那样简单。
设置区域的背景和文本颜色:(感谢William Jockusch和Dj S)
- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{
if ([view isKindOfClass: [UITableViewHeaderFooterView class]]) {
UITableViewHeaderFooterView* castView = (UITableViewHeaderFooterView*) view;
castView.contentView.backgroundColor = [UIColor grayColor];
[castView.textLabel setTextColor:[UIColor grayColor]];
}
}
使用RubyMotion / RedPotion,将其粘贴到你的桌面屏幕:
def tableView(_, willDisplayHeaderView: view, forSection: section)
view.textLabel.textColor = rmq.color.your_text_color
view.contentView.backgroundColor = rmq.color.your_background_color
end
效果好极了!
Although func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) will work as well, you can acheive this without implementing another delegate method. in you func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? method, you can use view.contentView.backgroundColor = UIColor.white instead of view.backgroundView?.backgroundColor = UIColor.white which is not working. (I know that backgroundView is optional, but even when it is there, this is not woking without implementing willDisplayHeaderView
