您当前的位置: - C/C++ code
- (MKAnnotationView *)mapView:(MKMapView *)aMapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if(![annotation isKindOfClass:[MyAnnotation class]]) // Don't mess user location
return nil;
MKAnnotationView *annotationView = [aMapView dequeueReusableAnnotationViewWithIdentifier:@"spot"];
if(!annotationView)
{
annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"spot"];
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[(UIButton *)annotationView.rightCalloutAccessoryView addTarget:self action:@selector(openSpot:) forControlEvents:UIControlEventTouchUpInside];
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
annotationView.centerOffset = CGPointMake(7,-15);
annotationView.calloutOffset = CGPointMake(-8,0);
}
// Setup annotation view
annotationView.image = [UIImage imageNamed:@"pinYellow.png"]; // Or whatever
return annotationView;
}

取坐标区域，放大这个区域，放在一个View上显示在最上层。OK了

楼主想说地图上有一个蓝点，有淡蓝色光圈的那个效果吗？如果是那个的话，可以在ib中将你的mkmapview控件中的shows user location勾选，或者在你定义的mkmapview对象中：你的地图对象.showsUserLocation = YES;

楼上正解 地图对象.showsUserLocation = YES;

虚拟机好像默认是显示在欧洲还是美国的某个地方，不过真机可以显示你当前的位置
