【问题描述】:
我的分段表格视图中有一个标题,其中包含一个按钮,点击时会扩展其单元格,我在标题中也有一个向右的箭头,当点击标题时,我想将该箭头图像更改为一个向下的箭头,如何更改该部分的标题?特别是arrowButton
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let header = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 50))
let button = UIButton(frame: CGRect(x: 0, y: 0, width: tableView.frame.width - 30, height: 50))
button.setTitle(tableDataSource[section][0].mod.modType!, for: .normal)
button.titleLabel?.font = UIFont(name: "Helvetica neue", size: 20)
button.addTarget(self, action: #selector(headerPressed(sender:)), for: .touchUpInside)
button.titleLabel?.textAlignment = .left
button.tag = section
let arrowButton = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
arrowButton.setImage(UIImage(systemName: "chevron.right", compatibleWith: nil), for: .normal)
header.addSubview(arrowButton)
header.addSubview(button)
header.backgroundColor = UIColor.green
return header
}
@objc func headerPressed(sender: UIButton){
if(tableDataSource[sender.tag][0].clicked == false){
tableDataSource[sender.tag][0].clicked = true
} else {
tableDataSource[sender.tag][0].clicked = false
}
let sections = IndexSet.init(integer: sender.tag)
tableView.reloadSections(sections, with: .fade)
}
