I designed the header of the tableview in such a way that it is being interactive through check boxes made from button by changing images. When I clicked a check box it is checked and unchecked correctly.
What I want is when I click the check box, if it gets checked the the rest of the two checkboxes should get unchecked automatically. Below is the code.
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
}
and this is the custom header class
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

Declare a variable to keep track of the selected checkbox and update its value depending on that variable's status.
Inside func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? modify the code like
var selectedCheckBoxIndex:Int?
headerCell.checkBox_PlannedisOn = selectedCheckBoxIndex == 0 ? true : false
headerCell.checkBox_unPlannedisOn = selectedCheckBoxIndex == 1 ? true : false
headerCell.checkBox_BothisOn = selectedCheckBoxIndex == 2 ? true : false
if type == "Planned"{
//Planned CallBack
if isCalled == true {
print("Planned selected")
self?.fetchPlannedData()
self?.tableView.reloadData()
selectedCheckBoxIndex = 0
} 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()
selectedCheckBoxIndex = 1
} 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()
selectedCheckBoxIndex = 2
} else {
self?.DeSelect()
self?.tableView.reloadData()
print("both Not selected")
}
self?.checkBox_BothisOn = isCalled
}
}
