我使用下面的代碼在我的mapview中設置了一個自定義註釋。問題在於註釋圖像的位置不正確,它將它放在實際位置的右側而不是像使用常規引腳時一樣點。自定義註釋錯誤
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier];
if(annotationView)
return annotationView;
else
{
MKAnnotationView *annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:AnnotationIdentifier] autorelease];
annotationView.canShowCallout = YES;
annotationView.image = [UIImage imageNamed:[NSString stringWithFormat:@"townhouse.png"]];
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:@selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
annotationView.rightCalloutAccessoryView = rightButton;
annotationView.canShowCallout = YES;
annotationView.draggable = YES;
return annotationView;
}
return nil;
}
任何幫助都將不勝感激!
