为什么IB没有看到我的IBAction？

Question

我一直盯着这个太久了.

这里没有任何花哨的事情发生,我已经做了好几次,但Interface Builder坚决拒绝为我提供行动目标-(IBAction)slideDirections.我正处于公开发布并感到愚蠢的地步.所以,让我们撕裂.

这是我的.h:

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface PulseDetailController : UIViewController {
    NSDictionary *pulse;
    IBOutlet MKMapView *map;
    IBOutlet UIWebView *directions;
    IBOutlet UIView *directionsSlider;
    BOOL directionsExtended;
    IBOutlet UILabel *vendor;
    IBOutlet UILabel *offer;
    IBOutlet UILabel *offerText;
    IBOutlet UILabel *hours;
    IBOutlet UILabel *minutes;
    IBOutlet UILabel *seconds;
    IBOutlet UILabel *distance
}
@property (nonatomic, retain) NSDictionary *pulse;
@property (nonatomic, retain) MKMapView *map;
@property (nonatomic, retain) UIWebView *directions;
@property (nonatomic, retain) UIView *directionsSlider;
@property (nonatomic) BOOL directionsExtended;
@property (nonatomic, retain) UILabel *vendor;
@property (nonatomic, retain) UILabel *offer;
@property (nonatomic, retain) UILabel *offerText;
@property (nonatomic, retain) UILabel *hours;
@property (nonatomic, retain) UILabel *minutes;
@property (nonatomic, retain) UILabel *seconds;
@property (nonatomic, retain) UILabel *distance;

-(IBAction)slideDirections;

不应该 IBAction有发送者参数吗？喜欢:

-(IBAction)slideDirections:(id)sender;
