iPhone SDK Tableview Datasource singleton error

Question

I basically followed apple "TheElements" sample and changed "PeriodicElements" .h & .m to my own "SortedItems" .h & .m

During compile I get this error:

"Undefined symbols:
"_OBJC_CLASS_$_SortedItems", referenced from: __objc_classrefs__DATA@0 in SortedByNameTableDataSource.o ld: symbol(s) not found collect2: ld returned 1 exit status "

How do i figure this out? hehe

Answer 1

That's a linker error. Most likely you forgot to add SortedItems.m to your project so it's not compiling and linking the implementation of SortedItems.

The other possibility is that you misspelled SortedItems in your @implementation statement.
