Objective c 触摸覆盖

4个文件，用于2个视图控制器，firstviewcontroller和MyOverlayView。MyOverlayView只接收触摸并发送应由firstviewcontroller接收的通知。我在overlayview上收到触摸事件，但在firstviewcontroller上未收到通知。有什么想法吗

FVC头

#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#import "MyOverlayView.h"

extern NSString *const OverlayViewTouchNotification;

@interface FirstViewController : UIViewController {
    MPMoviePlayerViewController *mvc;
    MyOverlayView *overlayView;
    NSArray *keyArray;
    NSMutableDictionary *urlDic;
}

@property (nonatomic, retain) MPMoviePlayerViewController *mvc;
@property (nonatomic, retain) IBOutlet MyOverlayView *overlayView;
@property (nonatomic, retain) NSArray *keyArray;
@property (nonatomic, retain) NSMutableDictionary *urlDic;

-(void)playMovieAtURL:(NSDictionary *)dic:(NSArray *)array:(int) rand;
-(void)overlayViewTouches:(NSNotification *)notification;
-(void)loadArray;
-(void)reset;
@end

MyOverlayView标题

#import <UIKit/UIKit.h>


@interface MyOverlayView : UIView {
}

- (void)awakeFromNib;
- (void)dealloc;
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;

@end

我没有为通知添加观察员。一切都搞定了。
