Change the sections header background color in UITableView using an array of headers
提问by Jp4Real
I have a array of headers that I use
我有一个我使用的标题数组
let sectionHeaderTitleArray = ["test1","test2","test3]
and they are showed using
它们显示使用
func tableView[tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return self.sectionHeaderTitleArray[section] as String
}
Now all of this works fine but I would like to modify the background color of the headers so that they are more visible (Darker Color)
现在所有这些工作正常，但我想修改标题的背景颜色，使它们更明显（深色）
any idea if I can do this in a simple line or do I need to use a custom cell to create this
任何想法我是否可以在一条简单的行中做到这一点，或者我是否需要使用自定义单元格来创建它
thanks
谢谢

func tableView(tableView: UITableView, ViewForHeaderInSection section: Int) -> UIView? {
return self.tableView.backgroundColor = UIColor.lightGrayColor()
}

Instead of using the
而不是使用
func tableView(_ tableView: UITableView,titleForHeaderInSection section: Int) -> String?
data source method, you can use the
数据源方法，您可以使用
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
delegate method and simply customize the UIViewreturned as you wish.
委托方法并根据需要简单地自定义UIView返回的值。
For example set the text of the UILabeltextLabelto your desired value and the backgroundColorto the desired UIColor.
例如，将 的文本设置UILabeltextLabel为您想要的值，并将backgroundColor设置为所需的UIColor。
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let returnedView = UIView(frame: CGRectMake(x, y, width, height)) //set these values as necessary
returnedView.backgroundColor = UIColor.lightGrayColor()
let label = UILabel(frame: CGRectMake(labelX, labelY, labelWidth, labelHeight))
label.text = self.sectionHeaderTitleArray[section]
returnedView.addSubview(label)
return returnedView
}

let label = UILabel(frame: CGRect(x: x, y: y, width: width, height: height))
label.text = self.sectionHeaderTitleArray[section]
returnedView.addSubview(label)
return returnedView

If you're using only titleForHeaderInSection :
如果您只使用 titleForHeaderInSection ：
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
(view as! UITableViewHeaderFooterView).contentView.backgroundColor = UIColor.black.withAlphaComponent(0.4)
(view as! UITableViewHeaderFooterView).textLabel?.textColor = UIColor.white
}

And, if you want different header background (and/or text) colors for each section:
而且，如果您想要每个部分的标题背景（和/或文本）颜色不同：
override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {

switch section {
case 0:
headerView.backgroundView?.backgroundColor = .red

case 1:

headerView.textLabel?.textColor = .white
case 2:
headerView.backgroundView?.backgroundColor = .yellow
headerView.textLabel?.textColor = .black

If you are using titleForHeaderInSection, then the easiest way is to add in viewDidLoad():
如果您正在使用titleForHeaderInSection，那么最简单的方法是在 viewDidLoad() 中添加：
self.tableView.backgroundColor = UIColor.clear
For some reason, setting ClearColor for Background in the View section for the TableView in the Interface Builder doesnt always set it to transparent. But adding this one line in the code (for me at least) does.
出于某种原因，在 Interface Builder 中为 TableView 的 View 部分中的 Background 设置 ClearColor 并不总是将其设置为透明。但是在代码中添加这一行（至少对我而言）确实如此。
