I did not find the answer to the question why I cannot add a data model to an existing project. Therefore, given the fact that creating a project from scratch using basic data for storage does create a data model, I am trying to move the entire project to a new project containing a data model.
No matter how I try to do this, at some point a new project will not be created. In my first attempt, I tried just to drag the drops from one to another, clear all the goals and build ... catastrophically.
Having tried several different approaches, the closest that I came to success was as follows:
created a new project (same name as my existing project)
tie the necessary structures
copy resources i.e. plists, icons, picts
create all classes in a new project
copy the contents of each .f and .m files of each class that does not refer to any other class. For each class, delete the .xib file and copy the .xib file from an existing project, clear all targets, check all the links in .xib, build.
work your way through the remaining classes, as in step 5, to ensure that all reference classes are always created first.
Following this methodology, I go to my last 2 classes and get the character (s) that did not find the error in the link to one of the first classes that I created. This error, as far as I can tell, has something to do with the fact that the framework is not connected correctly, but I cannot figure out how to fix it.
Is there a better way to do this.
