So, after I scratched my head silly for several minutes, it suddenly
came to me. If I'm going to use a property, I *must* refer to it as
object.property rather than simply as property. In the specific
example I had, I should not have replaced all those repeated chunks
of code with
textFieldPreviousContent = textField.text;
but with
self.textFieldPreviousContent = textField.text;
This is why I never use the same property name as ivar name.
Many people use the _ prefix for ivars, but whatever prefix or suffix
you choose, give the ivar a different name, and then you know when
you're accessing the ivar and when you're using the setter/getter.
@synthesize textFieldPreviousContent = _textFieldPreviousContent;
Enjoy,
Peter.
