Center page control in its frame #4

Closed amarcadet closed 8 years ago

amarcadet commented 8 years ago

I'm facing an issue with the FilledPageControl where the items are not centered horizontally in the frame of the page control.

IB displays an error if I don't set a width or x constraint so the page control can't center itself in its superview. If I apply a center horizontally constraint it doesn't fix the error either.

@amarcadet Each page control has a calculated intrinsicContentSize and therefore doesn't need width or height constraints, setting a top constraint and horizontally centered constraint will do the trick. If for some reason you are unable to get IB to cooperate, you can set a placeholder size w/in IB and the intrinsicContentSize will be respected at runtime.

Nice catch on the placeholder size, because it looks like the intrinsicContentSize is not working.
