我的注释(homeMark)未显示在mapView中。 我做了我的viewController代表在IBXcode 4.3.3 Mapview,注释未显示
出于某种原因,在委托方法 如果([注释isKindOfClass:[HomeMark类]){
失败.....注释不是“部分Homemark“类...
我在做什么错?
代码...
- (IBAction)clubHouse:(id)sender{
MKCoordinateRegion region = { {0.0, 0.0 } , {0.0,0.0} };
region.center.latitude = 55.305858;
region.center.longitude = 12.386036;
CLLocationCoordinate2D coord = {
.latitude = region.center.latitude,
.longitude = region.span.longitudeDelta};
HomeMark *homeMark = [[HomeMark alloc]
initWithCoordinate:coord
andMarkTitle:@"Klubhus"
andMarkSubTitle:@"Stevns Cykel Motion"];
[mapMyView addAnnotation:homeMark];
[mapMyView setMapType:MKMapTypeStandard];
[mapMyView setZoomEnabled:YES];
[mapMyView setScrollEnabled:YES];
region.span.longitudeDelta = 0.007f;
region.span.latitudeDelta = 0.007f;
[mapMyView setRegion:region animated:YES];
//[mapMyView setDelegate:sender];
mapMyView.showsUserLocation = YES;
}
而且ViewForAnnotation。
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = @"MyLocation";
if ([annotation isKindOfClass:[HomeMark class]]) {
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
}
else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
return annotationView;
}
return nil;
}
我还是不明白为什么人们投票下来,不说为什么?就是刚刚#1全巨魔? – Sirens
