Re: Syntax error in header file

usually when you implemented your own objects like :

@interface MyOwnObject

{

MyOwnSecondObject *lpSO;

}

@end

you need to tell the compiler that MyOwnSecondObject is a class you implemented yourself with the following line before the interface:

@class MyOwnSecondObject; //to specify you implements elsewhere

@interface MyOwnObject

{

MyOwnSecondObject *lpSO;

}

@end

so in your example, why not trying declare before your interface :

@class KCLine;

@class KCLineFactory;

@class KCColor;

what's the result ???

I'm sure this is simple, but I'm new to Obj-C, so I can't figure it out.

I've modified the QuartzLines Cocoa project to test drawing lines as flyweights.  I've created a singleton factory called KCLineFactory that stores an NSMutableDictionary of KCLine objects

I'm getting the following compiler error:

/Users/ryan/Downloads/QuartzLines/KCLineFactory.h:20: error: syntax error before 'KCLine'

and here is KCLineFactory.h:

10: #import "KCLine.h"

11: #import "KCColor.h"

12:

13: @interface KCLineFactory : NSObject 

14: {

15: NSDictionary *linesByColor;

16: }

17:

18: + (KCLineFactory *)sharedKCLineFactory;

19:

20: - (KCLine *)getLineWithColor:(KCColor *)color;

21:

22: @end

KCLine and KCColor are objects defined in KCLine.m and KCColor.m

Where is the syntax error?

Thanks
