ios - UICollectionViewCell height increase incorrectly on iPhone 6 -

i using uicollectionview , using custom uicollectionviewcell. user created posts showed on news feed screen. based on length of text, increasing height of cell. there strange spacing appears under "say something" text field.

when user enters text pressing enter, it's works well. if user enters number of lines without pressing enter issue occurs.

this code works on iphone 5 not on iphone 6 , 6 plus. stuck on issue since last 1 week. issue related iphone 6 , 6 plus only?

i didn't find relevant question problem that's why asking new question.
