How do I position views in Interface Builder for both 3.5” and 4” Retina?

Question

I want to position a UIView so it appears in the centre on both 3.5” and 4” Retina screens. What is the best way to do this? If I turn off all the Autosizing bars I would expect

Answer 1

To center view in its parent (container) view in IB with autolayout:

• Select you view
• go to menu and select Editor->Align->Horizontal/Vertical Center in Container option

However you can use autolayout only if you support iOS 6 and later, if you target earlier OS versions you'll have to use other approaches (e.g. setting centring view with code as Eric suggested)
