Thanks to all who replied to my pleas for help.
I took Bill and Scott's suggestions to heart and produced the answer
I needed: Dynamic Typing which allows me to avoid circularity etc.
Good. BTW: Nice paintings.
I post the complete solution as an example and to check that I'm not
running close to the wind by using a dummy class definition. The
code gets no compiler warnings.
You don't need the dummy class.
I'd do it something like this (Mail Code -- this probably won't
compile).
Only I'd also pull out all of the #imports and move to using a shared
precomp for the project...
// AnonTargetClass.h
#import <Cocoa/Cocoa.h>
@interface AnonTargetClass : NSObject {
}
- (void) printFloat:(float)pF;
// AnonTargetClass.m
#import "AnonTargetClass.h"
@implementation AnonTargetClass
- (void) printFloat:(float)pF {
NSLog(@"%7.3f",pF);
}
// CallingClass.h
#import <Cocoa/Cocoa.h>
@class AnonTargetClass;
@interface CallingClass : NSObject {
}
- (void) callPrintConstFloat:(AnonTargetClass *)pId;
- (void) callPrint:(id)pId zFloat:(float)pF;
// CallingClass.m
#import "CallingClass.h"
#import "AnonTargetClass.h"
@implementation CallingClass
- (void) callPrintConstFloat:(AnonTargetClass *)pId {
[pId printFloat:99.99];
}
- (void) callPrint:(id)pId zFloat:(float)pF {
[pId printFloat:pF];
}
// main.m
#import <Cocoa/Cocoa.h>
#import "AnonTargetClass.h"
#import "CallingClass.h"
int main(int argc, char *argv[])
{
AnonTargetClass * atcObj = [[AnonTargetClass
alloc]init];
CallingClass * callingObj = [[CallingClass
alloc]init];
[callingObj callPrintConstFloat:atcObj];
[atcObj printFloat:88.88];
}
