iphone - 为什么 IB 看不到我的 IBAction？

Question

我已经盯着这个看了太久了。

这里没有什么奇怪的事情发生，我已经这样做了几十次，但 Interface Builder 坚决拒绝为我提供 -(IBAction)slideDirections 的操作目标。我现在愿意公开发帖，但又觉得自己很愚蠢。所以让我们撕裂吧。

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;

IBAction 不应该有一个发送者参数吗？喜欢:

-(IBAction)slideDirections:(id)sender;
