Is it possible to use AutoLayout with UITableView's tableHeaderView?

Question

Since I discovered AutoLayout I use it everywhere, now I\'m trying to use it with a tableHeaderView.

I made a subclass of

I know this is an old post but After going through all the SO posts regarding this and passing a whole afternoon playing with this, I finally came up with a clean and yet very simple solution

First of all, My view hierarchy looks like this:

1. Table View
   2. View tableHeaderView
      3. View with an outlet called headerView

Now inside the View (No.3), I set up all the constraints as I would normally including the bottom space to container. This will make the container (i.e. 3.View i.e. headerView) to size itself based on it's subviews and their constraints.

After that, I set the constraints between 3. View and 2. View to these:

1. Top Space to container: 0
2. Leading Space to container: 0
3. Trailing Space to container: 0

Notice that I omit intentionally the bottom space intentionally.

Once all of this is done in the storyboard, everything that's left to do is paste those three lines of codes:

if (self.headerView.frame.size.height != self.tableView.tableHeaderView.frame.size.height) {
    UIView *header = self.tableView.tableHeaderView;
    CGRect frame = self.tableView.tableHeaderView.frame;
    frame.size.height = self.headerView.frame.size.height + frame.origin.y;
    header.frame = frame;
    self.tableView.tableHeaderView = header;
}
