Answer 1

You must be using data object whose data is used to show in table view just add one property in it isSelected . Lets name the array as "data".
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[data objectAtIndex:[indexPath row]].isSelected=YES;
[tableView reloadData];//or just row
}
And in didDeselectRowAtIndexPath
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
[data objectAtIndex:[indexPath row]].isSelected=NO;
[tableView reloadData];//or just row
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
//initial code
//addd this code
if([data objectAtIndex:[indexPath row]].isSelected){
//set checked image
}else {
//set unchecked image
}
}

you have to set property of cell
when you select the cell.
cell.selected = YES;
and when you deselect the cell then
cell.selected = NO;
if your tableview reload than you have to do this in cellForRowAtIndexPath Method
because when you reload the table than you have to remember the cell selection state.
In your code there is never called tableView didDeselect method
didDeselect only called when your tapped cell is selected.
Hope this will helps you
