Problem building the Random app



I just started going through the book this week and am having a bit of a problem. I am building the random number generator app and have done what I thought were all the steps through “Edit the Implementation File”.

After building the app the run running of it shows none of the objects placed into the app in the previous steps. When going back to see what I may have missed, I see in figure 2.15 that the push buttons created in the previous steps appear to be in the app as it should be when run (I hope this makes sense). However, my Xcode window does not show this. It shows the 3 push buttons on the grid and not within the “app”.

What did I miss?

Thanks for your help.



Hi, on page 13 the option “Class Prefix” must be empty !!
