Question

我在mapView中使用下面的代码添加按钮，但是按钮点击事件只在左侧工作，它在右侧不起作用。

MKPinAnnotationView *pinAnnotation = nil;
if(annotation != beerMapView.userLocation)
{
    static NSString *defaultPinID = @"myPin";
    pinAnnotation.pinColor = MKPinAnnotationColorRed;
    pinAnnotation = (MKPinAnnotationView *)[beerMapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
    if ( pinAnnotation == nil )
        pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
    NSLog(@"PinAnnotation: %@",NSStringFromCGRect(pinAnnotation.frame));
    pinAnnotation.canShowCallout = YES;
    pinAnnotation.image = [UIImage imageNamed:@""]; //Set blank pin image

    UIImageView *pinImage = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 40, 40)];
    pinImage.image = [UIImage imageNamed:@"ic_pin.png"];

    UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [infoButton setImage:[UIImage imageNamed:@"ic_pin.png"] forState:UIControlStateNormal];
    infoButton.frame = CGRectMake(0, 0, 40, 40);
    pinAnnotation.rightCalloutAccessoryView = infoButton;
    [infoButton addTarget:self action:@selector(detailBtnClk:) forControlEvents:UIControlEventTouchUpInside];
    [pinAnnotation addSubview:infoButton];
}

infoButton - ＆gt;左侧部分（0到20）按钮单击事件工作。（调用detailBtnClk）
infoButton - ＆gt;右侧部分（21到40）按钮单击事件不起作用。（不能调用detailBtnClk）

感谢任何帮助。
