iphone - 单击事件在 map View 中无法正常工作

Question

我使用下面的代码在mapView中添加按钮，但按钮单击事件仅适用于左侧尺寸，它不适用于右侧。

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 -> 左侧部分(0 到 20)按钮单击事件工作。 (调用detailBtnClk)
infoButton -> 右侧部分(21 至 40)按钮单击事件不起作用。 (无法调用detailBtnClk)

感谢任何帮助。

不要提供按钮类型 roundRect，而是提供 UIButtonTypeDetailDisclosure
