ios - UICollectionView Cell + UiLabel with AutoLayout -
i'm trying pin uilabel it's parent cell. added 4 constraints (top, leading, trailing, bottom) which works fine on ios 8.0 not on ios 7.x. please see image below:
what doing wrong? please advise!
edit #1
it seems it's broken since xcode 6 gm. approach working fine in xcode 6 beta 7.
moreover, if decrease inner view's width, throws following warning:

overriding custom cell's layoutsubviews possible workaround:
override func layoutsubviews() { contentview.frame = bounds super.layoutsubviews() }
