in iOS 7 viewForHeaderInSection section is starting from 1 not from 0
Just encountered exactly the same issue, and the resolution turns out very simple.
Just implement this delegate method:
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{ return 20;}Form Apple UITableViewDelegate Protocol Reference, it mentioned

The returned object can be a UILabel or UIImageView object, as well as a custom view. This method only works correctly when tableView:heightForHeaderInSection: is also implemented.
Swift 3 Version:
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat { return 60}
