Hi All,
I'm learning Obj-C, having mostly a Java background. Because of the large
differences between these two languages I'm experiencing some troubles. One
of those is the following:
Often the need arises to have classes import each others header files. When
this happens, the compiler throws up a compiling error. I was hoping the use
of 'import' instead of 'include' would solve this, but it apparently does
not. Still, I have found the following workarounds:
- mostly, only one class needs to create objects of the other's class. The
other class just needs a reference, and this reference can be 'NSObject' if
need be.
- use the @class directive so the compiler knows of the existence of the
class, without importing the header file.
These 'solutions' still result in comiler warnings.
- create a 'stub' header file to be imported by the class that only needs a
reference, which does not import its own header.
All of this seems quite complicated (I hope I'm making sense), and I'm sure
there is an elegant solution to this.
Please help this Obj-C newbie
