error: expected specifier-qualifier-list before...in Objective C ?
- by Ridwan
Hi guys. Whenever I build the following code, I get the error above.
//Controller.h
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "PolygonShape.h"
#import "PolygonView.h";
@interface Controller : NSObject
{
IBOutlet UIButton *decreaseButton;
IBOutlet UIButton *increaseButton;
IBOutlet UILabel *numberOfSidesLabel;
IBOutlet PolygonShape *shape;
IBOutlet PolygonView *shapeView;
}
- (IBAction)decrease;
- (IBAction)increase;
- (void)awakeFromNib;
@end
//Controller.m
#import "Controller.h"
@implementation Controller
@end
However, when I replace the import statement and put a forward class reference instead, the code compiles.
//Controller.h
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "PolygonShape.h"
@class PolygonView;
@interface Controller : NSObject
{
IBOutlet UIButton *decreaseButton;
IBOutlet UIButton *increaseButton;
IBOutlet UILabel *numberOfSidesLabel;
IBOutlet PolygonShape *shape;
IBOutlet PolygonView *shapeView;
}
- (IBAction)decrease;
- (IBAction)increase;
- (void)awakeFromNib;
@end
//Controller.m
#import "Controller.h"
#import "PolygonView.h"
@implementation Controller
@end
Can anyone explain?
