如何生成事件

Question

我創建了一個子類的UIView的

#import <UIKit/UIKit.h> 


@interface MeeSelectDropDownView : UIView { 
    UILabel *mainText; 
    UIImage *bgImg; 
    UIImageView *bgView; 
    UIImageView *originView; 
    NSMutableArray *labelArray; 
    int selectedItem; 
    BOOL inSelectTag; 
    float _defaultHeight; 
} 

@property (nonatomic , retain) UIImage *bgImg; 
@property (nonatomic , retain) UIImageView *bgView; 
@property (nonatomic , retain) NSMutableArray *labelArray; 
@property (nonatomic , retain) UIImageView *originView; 
@property (nonatomic , retain) UILabel *mainText; 
@property (nonatomic , readonly) int selectedItem; 


- (void) setViewHeight:(float)aheight; 
-(void) showDropList; 
-(void) hiddenDropList; 
-(void) setStringByArray:(NSArray*)array; 

-(void)hiddenLabels 
{ 
    for(UILabel *aLabel in labelArray){ 
     [aLabel removeFromSuperview]; 
    } 
} 

是否有可能生成功能的事件「hiddenLabels」通知，並做出頭

感謝

InterDev中

這是完全不清楚你想要做什麼。

建議：您可以考慮發佈NSNotification，或者使用KVO（Key Value Observing）註冊觀察員。
