objective c - iOS 9 iPad split screen completion/finished notification -


i implementing new feature in ios 9 new ipads of having multitasking of 2 apps split screen.

i can't seem find completion method of when split screen adjustment has finished after user has dragged app view size handle.

how notify app app being run in split screen?

note: different uisplitviewcontroller. referring multitasking of 2 apps in split screen, not uisplitviewcontroller

when user alters split screen sizes root view layout it's subviews new size, can implement viewdidlayoutsubviews in view controller.

-(void)viewdidlayoutsubviews {     if(!cgsizeequaltosize(self.lastframesize,self.view.frame.size))     {         nslog(@"size changed:(%f x %f)",self.view.frame.size.width, self.view.frame.size.height);     }     self.lastframesize=self.view.frame.size; }
