title: Autoresize UICollectionViewCells for different IPhones devices
body: <p>Some time ago i upgrade xcode and found some changes in storyboard designing. So before, I just create UICollectionView controller with UICollectionViewCell. I set manualy width and height of the cell on it and for all subItems in cell. So, when I run app on different iphones it always have different size, but same spaces between cells. And It also resize cells and content in it. See screenshots for Iphone5S and iphone6<img src="https://i.stack.imgur.com/uvxz4.png" alt="enter image description here"></p>

  <p>Sa U can see spaces between cells are different in iphone5S and Iphone6. So how can I set regular size for space between cells and make cells bigger for different iphones. My app is only for Iphones with portrait mode</p>
