ExpandableTableView: Only 1 row can be expanded at any one time - ios

Question

I am using ExpandableTableView.
Here's a link!
Only 1 row can be expanded at any one time while other should collapsed.
When a row is expanded, any tap on the screen will collapse the expanded row.
How can i get that?

Answer 1

In ExpandableTableView.h
Take previous section variable
NSInteger presection;
In ExpandableTableView.m
in - (id)initWithCoder:(NSCoder *)aDecoder Method set presection intial Value
presection=-1;
Replace didSelectRowAtIndexPath
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// either expand the section or call the delegates method if already expanded
if ([_expandedSectionIndexes containsIndex:indexPath.section]) {
// we're already expanded
[self contractSection:presection]; // Contrace Previos Section
if (indexPath.row == 0) {
// close the section
[self contractSection:indexPath.section];
[super deselectRowAtIndexPath:indexPath animated:YES];
} else {
if ([_expandableDelegate respondsToSelector:#selector(tableView:didSelectRowAtIndexPath:)]) {
[_expandableDelegate tableView:self didSelectRowAtIndexPath:[NSIndexPath indexPathForRow:indexPath.row - 1 inSection:indexPath.section]];
}
}
} else if (indexPath.row == 0 && _ungroupSingleElement && [_expandableDataSource tableView:self numberOfRowsInSection:indexPath.section] == 1) {
if ([_expandableDelegate respondsToSelector:#selector(tableView:didSelectRowAtIndexPath:)]) {
[_expandableDelegate tableView:self didSelectRowAtIndexPath:indexPath];
}
} else {
if (presection!=-1) {
[self contractSection:presection];
}
presection=indexPath.section;
[self expandSection:indexPath.section];
[super deselectRowAtIndexPath:indexPath animated:YES];
}
}
