Question

在我的地图上，我有rightCalloutAccessoryView个UIButtonTypeDetailDisclosure。我想检测用户是否点击注释的中心或UIButtonTypeDetailDisclosure。例如，如果他点击中心：执行名为XYZ的segue，如果UIButtonTypeDetailDisclosure上的点击：执行一个名为ABC的序列。

这是我的代码。问题是UIButtonTypeDetailDisclosure和注释执行名为＆＃34; infoDetail＆＃34;的相同segue。我尝试使用rightCalloutAccessoryView和leftCalloutAccessoryView上的标记进行不同配置，以检测哪一个被点按，但如何在右侧使用UIButtonTypeDetailDisclosure检测注释的中心？

- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {
    MKAnnotationView *aView;
    for (aView in views) {
        if (![aView.annotation isKindOfClass:[MKUserLocation class]]) {
            MKAnnotationView* annotationView = aView;

            annotationView.rightCalloutAccessoryView = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
            annotationView.rightCalloutAccessoryView.tag = 1;

            annotationView.leftCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeContactAdd]; 
            annotationView.leftCalloutAccessoryView.tag = 2;
        }
    } }


- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
    if ([control tag] == 1) {
        // Right Accessory Button Tapped
        [self performSegueWithIdentifier:@"infoDetail" sender:self];

    } else if ([control tag] == 2) {
        // Left Accessory Button Tapped
        [self performSegueWithIdentifier:@"contactDetail" sender:self];
    } }

我在mapView上使用带触摸手势的自定义按钮制作了这个。我不认为这是处理你的项目的干净方式，但它对我有用。我用自定义注释视图SMCalloutView做了这个。 https://github.com/nfarina/calloutview

UIButton *leftDisclosure = [UIButton buttonWithType:UIButtonTypeCustom];
 leftDisclosure.backgroundColor = [UIColor clearColor];
topDisclosure.frame = theframeYouWant;

[topDisclosure addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(disclosureTapped:)]];

annotationView.rightAccessoryView = topDisclosure;

这很棘手，我希望它会对你有所帮助。

检测用户是否点击注释的中心或右侧的UIButtonTypeDetailDisclosure？
