I want to restrict certain sections of my tableview to only allow 1 cell to be selected, as of right now all my cells can be selected regardless of the section it's in
There is a little twist however : My sections are an [array] and change dynamically depending on different variables.
My sections are themselves each, a Variable, so I can pinpoint to them programmatically like this :
var section1 = [NSDictionary(objects: [NSLocalizedString("Alcohol use less than 24 hours", comment:""), 2],
As said before however, section1 might need to be restricted while section4 might not.
Some code from the tableView :
// checkmarks when tapped
func tableView(_ tableView: UITableView, didSelectRowAtIndexPath indexPath: IndexPath) {
if let cell = tableView.cellForRow(at: indexPath) {
if self.selectedIndexPaths.contains(indexPath) {
cell.accessoryType = .none
cell.backgroundColor = UIColor.clear
self.selectedIndexPaths.remove(indexPath)
if CrewMembersNumber == "1" {
if((indexPath).section == 0) {
self.section1score -= section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section3score -= section3[(indexPath).row].object(forKey: "value") as! Int
}
} else if CrewMembersNumber == "2" {
if((indexPath).section == 0) {
self.section1score -= section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section2score -= section2[(indexPath).row].object(forKey: "value") as! Int
}
} else if CrewMembersNumber == "3" {
if((indexPath).section == 0) {
self.section1score -= section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section5score -= section5[(indexPath).row].object(forKey: "value") as! Int
}
} else {
// if crewmemebernumber doest return 1-2 or 3
if((indexPath).section == 0) {
self.section1score -= section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section4score -= section4[(indexPath).row].object(forKey: "value") as! Int
}
}
} else {
cell.accessoryType = .checkmark
cell.backgroundColor = UIColor (red:236/255.0, green: 236/255, blue: 236/255, alpha: 1.0)
self.selectedIndexPaths.add(indexPath)
if CrewMembersNumber == "1" {
if((indexPath).section == 0) {
self.section1score += section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section3score += section3[(indexPath).row].object(forKey: "value") as! Int
}
} else if CrewMembersNumber == "2" {
if((indexPath).section == 0) {
self.section1score += section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section2score += section2[(indexPath).row].object(forKey: "value") as! Int
}
} else if CrewMembersNumber == "3" {
if((indexPath).section == 0) {
self.section1score += section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section5score += section5[(indexPath).row].object(forKey: "value") as! Int
}
} else {
// if crewmemebernumber doest return 1-2 or 3
if((indexPath).section == 0) {
self.section1score += section1[(indexPath).row].object(forKey: "value") as! Int
} else if((indexPath).section == 1) {
self.section4score += section4[(indexPath).row].object(forKey: "value") as! Int
}
}
}
self.updateToolbarAndLabel(self.totalScore)
self.tableView.reloadData()
}
}
func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel!.text = self.textForIndexPath(indexPath);
cell.textLabel!.font = UIFont(name:"Avenir", size:19)
cell.textLabel!.numberOfLines = 0
cell.selectionStyle = UITableViewCellSelectionStyle.none;
if(self.selectedIndexPaths.contains(indexPath)) {
cell.accessoryType = .checkmark;
cell.backgroundColor = UIColor (red:236/255.0, green: 236/255, blue: 236/255, alpha: 1.0)
} else {
cell.accessoryType = .none;
cell.backgroundColor = UIColor.clear
}
return cell
}
Right now the code behaves the same in every section, and all cells are selectable no problem, I want to be able to select only 1 cell in section4 and section5
my question goes like this,
1st : how can I create a variable or something else that keeps track of which sections need to be restricted (like section4 section need to be restricted so I need a way to "flag" them)
2nd : how can I restrict a section to only allow for 1 cell to be selected (and automatically deselect the last one selected)
thanks
