autolayout - Detecting iOS 8 Orientation change in UIView -


i detecting regular , compact size classes traitcollectiondidchange in ios8.

i trying fit particular set of data horizontally across screen , not fit in horizontal class regular on portrait ipad mini there plenty of space in landscape.

the problem horizontal sizeclass regular in portrait , landscape traitcollectiondidchange not fire , don't told orientation change.

i have heard reference viewwilltransitiontosize not available in uiview.

are apple saying not want ui layout diffs horizontal class regular - portrait , horizontal class regular - landscape?

if it's ok how told, in uiview, orientation change?

just add method -(void) layoutsubviews uiview subclass. called time view's dimensions change. don't forget call [super layoutsubviews] inside new method.

then can check self.traitcollection.verticalsizeclass , self.traitcollection.horizontalsizeclass see you're looking at.

-(void) layoutsubviews {     [super layoutsubviews];      //   code here... }
