iOS 13> swift 5
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){视图。tintColor = UIColor。红}
其他回答
基于@Dj的回答,使用Swift 3。这在iOS 10上运行得很好。
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
// Background color
view.tintColor = UIColor.black
// Text Color
let headerView = view as! UITableViewHeaderFooterView
headerView.textLabel?.textColor = UIColor.white
}
希望UITableViewDelegate协议中的这个方法能让你开始:
objective - c:
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
if (section == integerRepresentingYourSectionOfInterest)
[headerView setBackgroundColor:[UIColor redColor]];
else
[headerView setBackgroundColor:[UIColor clearColor]];
return headerView;
}
迅速:
func tableView(_ tableView: UITableView!, viewForHeaderInSection section: Int) -> UIView!
{
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))
if (section == integerRepresentingYourSectionOfInterest) {
headerView.backgroundColor = UIColor.redColor()
} else {
headerView.backgroundColor = UIColor.clearColor()
}
return headerView
}

{
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: 30))

headerView.backgroundColor = UIColor.red

替换[UIColor redColor]与任何你想要的UIColor。您可能还希望调整headerView的尺寸。
你可以这样做,如果你想头部自定义颜色。自iOS 6.0以来,这个解决方案工作得很好。
Objective - C:
[[UITableViewHeaderFooterView appearance] setTintColor:[UIColor redColor]];
迅速:
UITableViewHeaderFooterView.appearance().tintColor = .white
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;
}
使用UIAppearance,你可以为你的应用程序中的所有头部更改它,如下所示:
UITableViewHeaderFooterView.appearance()。backgroundColor = theme.subViewBackgroundColor
