Question

看看这段代码，看看你是否可以帮我修复它：

- (void)viewDidLoad
{
//Initialize the array and add annotations for the location on the map

annotations = [[NSMutableArray alloc] init];    
CustomAnnotation *annotation;
CLLocationCoordinate2D coordinate;

//1
coordinate.latitude = 25.220390105797264;

annotation.annotationIndex = @"123";

[annotations addObject:annotation];

[annotations addObject:annotation];

[annotations addObject:annotation];
//Set the region and zoom factor of the map view
MKCoordinateRegion region;

region.span.latitudeDelta = 0.01f;
region.span.longitudeDelta = 0.01f;
region.center.latitude = 25.216050105797264;
    region.center.longitude = 55.27905199798584;
    [sheikhZayedRoadMapView addAnnotations:annotations];

static NSString * const kPinAnnotationIdentifier = @"PinIdentifier";
MKAnnotationView *annotationView;

 //CustomAnnotation *customAnnotation =nil
annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:kPinAnnotationIdentifier];
if (!annotationView) {

    annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:kPinAnnotationIdentifier];
        annotationIndexLabel = [[Myriadproregular alloc] initWithFrame:CGRectMake(0, 3, 25 , 20)];
        annotationIndexLabel.font = [UIFont boldSystemFontOfSize:12];
        [annotationIndexLabel setBackgroundColor:[UIColor clearColor]];
        [annotationIndexLabel setTextColor:[UIColor whiteColor]];
        [annotationIndexLabel setTextAlignment:UITextAlignmentCenter];
        [annotationView addSubview:annotationIndexLabel];
        annotationView.canShowCallout = YES;
    annotationView.calloutOffset = CGPointMake(-5, 5);

}else {

    //Get the label if exists
    for (UIView *labelView in annotationView.subviews) {
        if ([labelView isKindOfClass:[UILabel class]]) {
            annotationIndexLabel = (Myriadproregular *) labelView;
            break;
        }
    }
}

if ([annotation isKindOfClass:[MKUserLocation class]]) {

    [annotationView setImage:[UIImage imageNamed:@"map_notify_bg.png"]];

}else {
    CustomAnnotation *customAnnotation = (CustomAnnotation *) annotation;
    [annotationIndexLabel setText:customAnnotation.annotationIndex];

    [annotationView setImage:[UIImage imageNamed:@"ico_inspector.png"]];
}

return annotationView;
}

问题是：

当我点击提供给didSelectAnnotationView的自定义图片时，我没有调用MKAnnotationView委托方法。

任何形式的帮助都将受到赞赏。

由于

Answer 1

[annotationView setCanShowCallout:NO]

这解决了我的问题，因为我不想在点击引脚时发出标注，但我想调用didSelectAnnotationView委托来调用。

由于

Answer 2

您是否在注释中添加title属性？您确定[annotationView setCanShowCallout:YES]设置正确吗？

Answer 3

创建mapview后是否设置了MKMapView的委托？

点击MKAnnotationView不会调用didSelectAnnotationView委托
