I have had no compiler issues until now. beginning chapter 22 with the first lines of code:
boxLayer = [[CALayer alloc] init];
leads to two errors, the first of which is:
Apple Mach-O linker (id) error “objc_class$_calayer”, …
“OBJC_CLASS$_CALayer”, referenced from:
Objc-class-ref in HypnosisView.o
Symbol(s) not found for architecture i386
I can’t find anything on how to resolve this.
