如何在objective-c中进行子视图，比如溢出：隐藏在CSS中？

When i tap on the view, it grow and its height is 187 and image is loaded and visible. When i tap on view second time, view is 43 pixel height but this image on this view is stil visible (content after y = 43 is visible). Is it possible to hide this content which is above 43 pixel height? (out of view).I've got view in XIB which has on start 43 pixe
