Hi all, I'm wanting to make a simple iOS app for work wherein employees get given an iPad mini and then each time they sell an item, they use the app to keep track of what they've sold. I'm using the Single-View application mode in Xcode 7, then using buttons with a modal link to each separate story board, here's an example. If an employee sells a t-shirt, this would be the process: 1) Press 'T-Shirt' button (modal link to the Design name story board) 2) Press 'Design Name' (modal link to Size story board) 3) Select the Size It is at this point I want to tell Xcode to +1 to the total of that size t-shirt to the days running total, but I'm not sure what the best way to hold that data would be. Does anybody have any suggestions? I'm relatively new to Xcode but I've done bits of light coding in the past. I'm not exactly fluent in any coding languages which I why I'm using the GUI in Xcode as apposed to just writing out the relevant strings of code. Any help would be appreciated! Thanks in advance to anyone who has spared some of there time to read this!
