You need add one key your datasource array and modify that key value depend upon button state on click action. Check below code for your reference
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
MyCustomTableViewCell *cell = (MyCustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"MyCustomTableViewCell"];
[cell.btnSelect addTarget:self action:#selector(btnSelectClick:) forControlEvents:UIControlEventTouchUpInside];
cell.btnSelect.selected = [[[self.arraySource objectAtIndex:indexPath.row] valueForKey:#"isSleected"] boolValue];
cell.btnSelect.tag = indexPath.row;
return cell;
}
- (void)btnSelectClick:(UIButton *)sender {
sender.selected = !sender.selected;
NSMutableDictionary *dicTemp = [NSMutableDictionary dictionaryWithDictionary:[self.arraySource objectAtIndex:sender.tag]];
[dicTemp setValue:[NSNumber numberWithBool:sender.selected] forKey:#"isSleected"];
[self.arraySource replaceObjectAtIndex:sender.tag withObject:dicTemp];
}
Here is arraySource in view did load
self.arraySource = [NSMutableArray array];
[self.arraySource addObject:#{#"name":#"name-1"}];
[self.arraySource addObject:#{#"name":#"name-2"}];
[self.arraySource addObject:#{#"name":#"name-3"}];
