I've a scenario where 9 UICollectionViewCell are generated programmatically. It should be arranged in 3*3 format in all iPhone variant.
Also the button size to get increased or decreased based on iPhone device. For eg., In iPhone 4s it should be small so that 3*3 format is arranged properly and in iPhone 6 Plus it should be big enough so that 3*3 format is achieved.
I had tried setting constraints programmatically but didn't get desired result.
How to set constraints programmatically to UICollectionViewCell such that purpose is achieved?
