Adding C++ Object to Objective-C Class
- by Winder
I'm trying to mix C++ and Objective-C, I've made it most of the way but would like to have a single interface class between the Objective-C and C++ code. Therefore I would like to have a persistent C++ object in the ViewController interface.
This fails by forbidding the declaration of 'myCppFile' with no type:
#import <UIKit/UIKit.h>
#import "GLView.h"
#import "myCppFile.h"
@interface GLViewController : UIViewController <GLViewDelegate>
{
myCppFile cppobject;
}
@end
However this works just fine in the .mm implementation file (It doesn't work because I want cppobject to persist between calls)
#import "myCppFile.h"
@implementation GLViewController
- (void)drawView:(UIView *)theView
{
myCppFile cppobject;
cppobject.draw();
}
