Im trying to pass an array between two VC. I understand how we are suppose to pass data forwards and backwards using segue, but for a tab bar controller you would have to pass data forwards and backwards? My storyboard flows like this Tab bar controller -> VC1/ VC2 im trying to pass data from VC1 to VC2, more specifically an array.

Have a look at this question: iPhone: How to Pass Data Between Several Viewcontrollers in a Tabbar App

Also the imho cleanest way is to use the NSNotificationcenter. It's simple: How to use NSNotificationcenter
