I'm trying to make two subclasses a class:
// Old code
- (void)setPaging {
[pagingScrollView addSubview:self.ImageScrollView];
}
@interface ImageScrollView : UIScrollView <UIScrollViewDelegate> {
UIView *imageView;
NSUInteger index;
}
@property (assign) NSUInteger index;
- (void)displayTiledImageNamed:(CGPDFPageRef)page size:(CGSize)imageSize;
@end
@implementation ImageScrollView
@synthesize index;
// ... my methods ...
@end
Changed to:
// NEW Code__________________________________________________________*
- (void)setPaging {
if (D == 1) {
// error: request for member 'ISVportrate' in something not a
// structure or union
[pagingScrollView addSubview:self.ISVportrate];
} else if (D == 2) {
//error: request for member 'ISVLandscape' in something not a
// structure or union
[pagingScrollView addSubview:self.ISVLandscape];
}
}
@class ISVportrate;
@class ISVLandscape;
@interface ImageScrollView : UIScrollView <UIScrollViewDelegate> {
UIView *imageView;
NSUInteger index;
}
@property (assign) NSUInteger index;
- (void)displayTiledImageNamed:(CGPDFPageRef)page size:(CGSize)imageSize;
@end
@interface ISVportrate : ImageScrollView {}
@end
@interface ISVLandscape : ImageScrollView {}
@end
@implementation ISVportrate : ImageScrollView
// error: property 'index' attempting to use ivar 'index' declared in
// super class of 'ISVportrate'
@synthesize index;
// ... my methods ...
@end
@implementation ISVLandscape : ImageScrollView
// error: property 'index' attempting to use ivar 'index' declared in
// super class of 'ISVLandscape'
@synthesize index;
// ... my methods ...
@end
I am not doing this right, am I? see above I have 4 errors… this is the first time I've made a class… help me understand, I think I've almost got it right.
