Where should I be setting autolayout constraints when creating views programmatically

Question

I see different examples where constraints are set. Some set them in viewDidLoad / loadView (after the subview was added). Others set them in the m

Answer 1

This should be done in ViewDidLoad, as per WWDC video from Apple and the documentation.

No idea why people recommend updateConstraints. If you do in updateConstraints you will hit issues with NSAutoresizingMaskLayoutConstraint with auto resizing because your views have already taken into account the auto masks. You would need to remove them in updateConstraints to make work.

UpdateConstraints should be for just that, when you need to 'update' them, make changes etc from your initial setup.
