Easy to use Expandable TableView with animated insertion and removal. The code is inspired by Apple's example DateCell
Copy JNExpandableTableView class into your project.
pod 'JNExpandableTableView'Replace your UITableView classes with JNExpandableTableView
To make a cell expandable just implement:
- (BOOL)tableView:(JNExpandableTableView *)tableView canExpand:(NSIndexPath *)indexPath
{
return YES;
}As there are no delegate interceptions you need to return the number of cells in this format:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return JNExpandableTableViewNumberOfRowsInSection((JNExpandableTableView *)tableView,section,20);
}To return an expanded Cell, check the indexPath and return the cell you need:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self.tableView.expandedContentIndexPath isEqual:indexPath])
{
static NSString *CellIdentifier = @"expandedCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
return cell;
}
else
{
NSIndexPath * adjustedIndexPath = [self.tableView adjustedIndexPathFromTable:indexPath];
static NSString *cellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.textLabel.text = [NSString stringWithFormat:@"Index: %ld",(long)adjustedIndexPath.row];
return cell;
}
}JNExpandableTableView is a subclass of UITableView and thus we are not replacing delegates and doing tricky interceptions. That is why you need to help this class in some datasource calls.
