Hi, I've made a few simple apps before (with the help of some people on these forums) and I'm back with more problems.
I want to make an app for laser enthusiasts such as I, where one can type in/select the power and wavelength of their laser, then the program will display a page of information about that laser with a back button to start over again.
I have made a very simple mockup of what the app should look like (I will make it pretty later
) Included in the screenshots is what I have done.
So far all I want to test is when I click the button labeled "Green" it will go to the next page. I right clicked on the button "Green" and dragged a line to the second view controller and selected "Push". However, when I run the app all I get is an error after clicking the "Green Button". I have included the error message as well.
I have NOT written any code anywhere yet...and I'm assuming that's why this won't work, however I've been researching the internet and can't find a clear answer on how to accomplish this very simple task.
Any help would be GREATLY appreciated! Thanks!
