为什么我看不到我的行动?

-(IBAction)slideDirections . 我现在愿意公开发帖,觉得自己很愚蠢。所以让我们扯开。

#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;
