Multiple selection with multiple sections in UItableview - ios

Question

If I select the first indexPath of first section , all the first indexPath of different sections gets selected like the image. How to rectify it?
if ([arraySelectedValue‌​s containsObject:array‌​StateNames[indexPath.‌​row]]) {
cell.imageCheck.imag‌​e =[UIImage imageNamed:#"check"]‌​;
} else {
cell.imageCheck.imag‌​e =[UIImage imageNamed:#"uncheck‌​"];
}

Answer 1

Change your code to the following.
if ([arraySelectedValue‌​s containsObject:indexPath])
{
cell.imageCheck.imag‌​e =[UIImage imageNamed:#"check"]‌​;
}
else
{
cell.imageCheck.imag‌​e =[UIImage imageNamed:#"uncheck‌​"];
}
and in didSelectRow method write the below code
if ([arraySelectedValues containsObject:indexPath])
{
[arraySelectedValues removeObject:indexPath];
}
else
{
[arraySelectedValues addObject:indexPath];
}
and reload the section or row

Answer 2

For this you need create a global arr to hold selected indexPath in your h file
NSMutable *arrSelectedIndex;
in your didSelectItemAtIndexPath you need to write below code.
-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
[self selectDeselectIndexpath:indexPath];
[collectionView reloadData];
}
// this method is used to toggle between selection and deselection
-(void) selectDeselectIndexpath : (NSIndexPath *) indexPath{
for (int i=0; i < arrSelectedIndex.count; i++) {
NSIndexPath *index = [arrSelectedIndex objectAtIndex:i];
if (index.row == indexPath.row && index.section == indexPath.section) {
[arrSelectedIndex removeObject:index];
return ;
}
}
[arrSelectedIndex addObject:indexPath];
}
// this method is used to select any indexPath
-(void) selectIndexpath : (NSIndexPath *) indexPath{
for (int i=0; i < arrSelectedIndex.count; i++) {
NSIndexPath *index = [arrSelectedIndex objectAtIndex:i];
if (index.row == indexPath.row && index.section == indexPath.section) {
return ; // This means indexPath already selected
}
}
[arrSelectedIndex addObject:indexPath];
}
// this method is used to deselect any indexPath
-(void) deselectIndexpath : (NSIndexPath *) indexPath{
for (int i=0; i < arrSelectedIndex.count; i++) {
NSIndexPath *index = [arrSelectedIndex objectAtIndex:i];
if (index.row == indexPath.row && index.section == indexPath.section) {
[arrSelectedIndex removeObject:index];
return ; // Indexpath found and remove from array
}
}
// Reaching over here means this indexpath not selected;
}
You can use any the above method as per you need.
