How to call .dylib

Its in the h Class file: @interface DebenuPDFLibraryCPLiteDylibObjC1115 : NSObject {
@private
void *dylibHandle;
int instanceID;
BOOL loadError;

and then the methods,example:

DebenuPDFLibraryFuncType119 DebenuPDFLibraryAddImageFromFile;
DebenuPDFLibraryFuncType46 DebenuPDFLibraryAddLinkToWeb;
DebenuPDFLibraryFuncType69 DebenuPDFLibraryAddStandardFont;
DebenuPDFLibraryFuncType22 DebenuPDFLibraryAddToBuffer;
DebenuPDFLibraryFuncType20 DebenuPDFLibraryAnsiStringResultLength;
DebenuPDFLibraryFuncType4 DebenuPDFLibraryCreateBuffer;

I think the dylib you downloaded cannot be used through declares as it seems it is intended for static linking into an Objective C project.
