我设计了tableview的页眉，使得它通过改变图像从按钮制作的复选框进行交互。当我点击一个复选框时，它会被正确选中并取消选中。带复选框的交互式表格视图页眉
我想要的是当我点击复选框，如果它被检查，其余的两个复选框应该自动取消选中。以下是代码。
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let identifierHeader:String = "SavedCallHeader"
let headerCell = tableView.dequeueReusableCell(withIdentifier: identifierHeader) as! SavedCallHeader
headerCell.checkBox_PlannedisOn = checkBox_PlannedisOn
headerCell.checkBox_unPlannedisOn = checkBox_unPlannedisOn
headerCell.checkBox_BothisOn = checkBox_BothisOn
headerCell.callBackForReload = { [weak self] (type,isCalled) -> Void in
print("is called Planned = \(type)")
print("is called Planned = \(isCalled)")
if type == "Planned"{
//Planned CallBack
if isCalled == true {
print("Planned selected")
self?.fetchPlannedData()
self?.tableView.reloadData()
} else {
self?.DeSelect()
self?.tableView.reloadData()
print("Planned Not selected")
}
self?.checkBox_PlannedisOn = isCalled
}else if type == "UnPlanned"{
//UnPlanned CallBack
if isCalled == true {
print("UnPlanned Selected")
self?.fetchUnPlannedData()
self?.tableView.reloadData()
} else {
self?.DeSelect()
self?.tableView.reloadData()
print("UnPlanned Not selected")
}
self?.checkBox_unPlannedisOn = isCalled
}else{
//Both CallBack
if isCalled == true {
print("Both Selected")
self?.fetchDate()
self?.tableView.reloadData()
} else {
self?.DeSelect()
self?.tableView.reloadData()
print("both Not selected")
}
self?.checkBox_BothisOn = isCalled
}
}
return headerCell
}
，这是自定义头类
class SavedCallHeader : UITableViewCell{
var callBackForReloadPlanned : ((Bool) ->())?
var callBackForReloadBoth : ((Bool) ->())?
var callBackForReloadUnPlanned : ((Bool) ->())?
var NameOfOnStatus : ((String) ->())?
var AnyOneIsOn:Bool = true
var callBackForReload : ((String,Bool) ->())?
// var checkBox_PlannedisOn:Bool = false
// var checkBox_BothisOn:Bool = true
// var checkBox_unPlannedisOn:Bool = false

可以为每个按键设置标签，当你点击某个按钮，然后取消选择基于标签的其他按钮。 –
