使用自定义单元格在3个UITabBar之间传输数据

I have read a lot of similar topics questions but this one is different. I have 3 tab bar controller and each tab bar controller have many custom static cells. Each cell has data like UISwitch, UIDatePicker, UITextField. I would like all of that data to get transferred from tab 1 to tab 3 and tab 2 to tab 3, so I can use it to calculate information and display it on tab 3. I have tried few things, but I am having problems setting up the segue and getting data from many custom cells into the tab1 controller and send it to tab 3 controller and also the same with tab2 to tab 3. I am having problem because Tab1 have 11 different custom cell classes, where all the data is being set. Any help will be highly appreciated. ThanksI have read a lot of similar topics questions b
