So I want to have a different type of custom cell but my problem is how can I add more if there is not enough space in a certain view in story board.
Select your view controller, and in the fourth tab of InterfaceBuilder, select 'freeform' in size.
OR
Inside the UIStoryboard, you can simply select your UIViewController and go directly to the fifth tab. Just change the Simulated Size from Fixed to Freeform .
It works for you
