UITableViewDataSource’s cellForRowAtIndexPath
For a certain row, use your custom cell that has the tableview.

UITableViewDelegate’s heightForRowAtIndexPath
Make sure your table view delegate method heightForRowAtIndexPath is appropriate so people can see your custom cell.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if(indexPath.row==0) { return 300.0f; } else { return 86.0f; |
The cell that contains the inner table
Create your tableview with its associated data array, then add it to the cell’s view hierarchy.
