我添加了带有两个按钮的自定义tableview标头,但是按钮被禁用,无法进行控件事件。我想要这样的布局。我是开发新手。任何建议或解决方案
我试图在ViewforHeaderSection函数的视图内部添加带有按钮的视图
func tableView(_ tableView:UITableView,viewForHeaderInSection部分:Int)-> UIView? {
let inviteSectionHeaderview = UIView.init(frame: CGRect(x:0, y:0, width: self.view.bounds.width, height: self.view.bounds.height))
let selectAllBtn = UIButton.init(frame:CGRect(x:16, y: inviteSectionHeaderview.bounds.height/2, width:130, height:20))
let sendButton = UIButton.init(frame:CGRect(x:inviteSectionHeaderview.bounds.width - 30, y: inviteSectionHeaderview.bounds.height/2, width:60, height:20))
selectAllBtn.setTitle("select all/Cancel", for: .normal)
selectAllBtn.backgroundColor = .black
sendButton.backgroundColor = .black
sendButton.setTitle("SEND", for: .normal)
self.contactsTable.addSubview(inviteSectionHeaderview)
inviteSectionHeaderview.addSubview(selectAllBtn)
inviteSectionHeaderview.addSubview(sendButton)
return inviteSectionHeaderview
}

您有两个选择:
UIView
选项2
创建您的UIView
。
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 30.0))
// Button1
let button1 = UIButton(frame: CGRect(x: 15.0, y: 0, width: 100, height: 28.0)
button1.setTitle("Button 1", for: .normal)
button1.addTarget(self, action: #selector(selectorButton1), for: .touchUpInside)
// Button2
let button2 = UIButton(frame: CGRect(x: tableView.frame.width-150, y: 0, width: 150, height: 30.0))
button2.setTitle("Button2", for: .normal)
button2.addTarget(self, action: #selector(selectorButton2), for: .touchUpInside)
button2.semanticContentAttribute = UIApplication.shared
.userInterfaceLayoutDirection == .rightToLeft ? .forceLeftToRight : .forceRightToLeft
headerView.addSubview(button1)
headerView.addSubview(button2)
return headerView
}
@objc func selectorButton1(_ sender : Any) {
}
@objc func selectorButton2(_ sender : Any) {
}
在这种情况下,创建y
和x
时必须正确设置UIView(frame: CGRect())
和UIButton(frame: CGRect())
的位置
编辑
从您的代码中,您只需要添加目标:
selectAllBtn.addTarget(self, action: #selector(selectorAllBtn), for: .touchUpInside)
sendButton.addTarget(self, action: #selector(selectorSendButton), for: .touchUpInside)
@objc func selectorAllBtn(_ sender : Any) {
}
@objc func selectorSendButton(_ sender : Any) {
}

您可以尝试使用此代码。
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
var headerView = tableView.dequeueReusableHeaderFooterView(withIdentifier: "headerView")
if headerView == nil {
headerView = UITableViewHeaderFooterView(reuseIdentifier: "headerView")
let button1 = UIButton(frame: CGRect(x: 8, y: 8, width: 80, height: 40))
button1.setTitle("Select", for: .normal)
button1.addTarget(self, action: #selector(self.buttonAction), for: .touchUpInside)
headerView?.addSubview(button1)
}
return headerView
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50 // set a height for header view
}
@objc func buttonAction(_ sender: UIButton) {
// write your code...
}
