Answer 1

When adding a subview to UITableView there are some specific requirements for the subview. Consider adding the subview to another view(superview) in your controller instead of UITableView.

"Auto Layout still required after executing -layoutSubviews" with UITableViewCell subclass

Answer 2

As a general solution to this problem, or at least a way of finding the cause of it:

• Turn on exception breakpoints
• Subclass UITableView and override layoutSublayersOfLayer:, just calling super
• Run your app - you will stop in your new method
• In the debugger, type po [self _autolayoutTrace]

This will show you a printout of every view in the window, with the views where auto layout has not been able to come up with a solution highlighted by asterisks or AMBIGUOUS LAYOUT. These are the views you need to investigate the constraints for.
