MKAnnotationView自定義標註 - 處理觸摸按鈕

Question

我正在使用J4n0標註代碼（github）在MapKit中實現自定義註釋。

在我的註釋（MyCalloutView）中，我使用了一個按鈕和一個標籤。

當我點擊我的按鈕時，會調用方法handleTouch，但發件人對應的UITapGestureRecognizer和sender.view總是等於我的註釋視圖，而不是按鈕。

MyCalloutView.h

@interface MyCalloutView : CalloutView 

@property (nonatomic, retain) IBOutlet UILabel* title; 
@property (weak, nonatomic) IBOutlet UIButton *clickButton; 

- (IBAction) handleTouch:(id)sender; 

- (id) initWithAnnotation:(CalloutAnnotation*)annotation; 

- (IBAction)onClickButton:(id)sender; 

@end 

MyCalloutView.m

@implementation MyCalloutView 

-(IBAction) handleTouch:(UITapGestureRecognizer *)sender { 
    //LogDebug(@"touch from : %@", sender); 
    UIButton *senderButton = (UIButton *)sender.view; 
    LogDebug(@"Sender class : %@ - Sender Tag : %d - Sender View class : %@", [sender class], sender.view.tag, sender.view.class); 
    LogDebug(@"Tap postion : (%f, %f)", [sender locationInView:sender.view].x, [sender locationInView:sender.view].y); 
    if(senderButton == self.clickButton){ 
     LogDebug(@"le clique vient de click button !!"); 
    } 
} 
[...] 

CalloutView.h @class CalloutAnnotation;

@interface CalloutView : BaseCalloutView 

- (IBAction) handleTouch:(id)sender; 
- (id)initWithAnnotation:(CalloutAnnotation*)annotation; 

@end 

CalloutView.m @implementation CalloutView

-(IBAction) handleTouch:(id)sender { 
    LogDebug(@"touch %@", sender); 
} 


- (id)initWithAnnotation:(CalloutAnnotation*)annotation 
{ 
    NSString *identifier = NSStringFromClass([self class]); 
    self = [super initWithAnnotation:annotation reuseIdentifier:identifier]; 
    if (self!=nil){ 
     [[NSBundle mainBundle] loadNibNamed:identifier owner:self options:nil]; 
    } 

    // prevent the tap and double tap from reaching views underneath 

    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)]; 
    [self addGestureRecognizer:tapGestureRecognizer]; 
    UITapGestureRecognizer *doubletapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)]; 
    doubletapGestureRecognizer.numberOfTapsRequired = 2; 
    [self addGestureRecognizer:doubletapGestureRecognizer]; 


return self; 
} 
@end
