我正在 iPhone 应用程序的 MapView 中开发自定义引脚。
这是代码：
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString *AnnotationViewID = @"annotationViewID";
MKAnnotationView *annotationView = (MKAnnotationView *)[myMapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];
if (annotationView == nil)
{
annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
}
if ([[annotation title] isEqualToString:NSLocalizedString(@"Current Location",@"")]) {
MKPinAnnotationView *pin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
//pin.pinColor = MKPinAnnotationColorRed;
annotationView = pin;
}
else
{
NSString *pin = [NSString stringWithFormat:@"pin%i.png",[[annotation imgNumber] intValue]];
annotationView.image = [UIImage imageNamed:pin];//Canviar la chincheta per numero
UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[annotationView setRightCalloutAccessoryView:button];
annotationView.annotation = annotation;
annotationView.canShowCallout = YES;
/********* Imagen a la izquierda en la burbuja *********/
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
// Set up the Left callout
UIButton *myDetailButton = [UIButton buttonWithType:UIButtonTypeCustom];
myDetailButton.frame = CGRectMake(0, 0, 23, 23);
myDetailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
myDetailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
// Set the image for the button
//[myDetailButton setImage:[UIImage imageNamed:@"botocorreu.png"] forState:UIControlStateNormal];
NSString *detailButton = [NSString stringWithFormat:@"%i",[[annotation imgNumber] intValue]];
[myDetailButton setImage:[UIImage imageNamed:detailButton] forState:UIControlStateNormal];
// Set the button as the callout view
annotationView.leftCalloutAccessoryView = myDetailButton;
annotationView.canShowCallout = YES;
}
return annotationView;
}
这很好用，但用红色图钉向我显示用户位置。
我检查了 IB 中的“显示用户位置”。
我想使用默认的蓝点，当用户移动时它会自动移动，这不正确吗？
我怎样才能做到这一点？
多谢。
将其添加到top of the viewForAnnotation method:
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
特殊的用户位置注释是类型MKUserLocation在这种情况下返回 nil 告诉地图视图为其绘制默认视图，即蓝点。
你也可以remove这些行，因为不再需要它们：
if ([[annotation title] isEqualToString:NSLocalizedString(@"Current Location",@"")]) {
MKPinAnnotationView *pin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
//pin.pinColor = MKPinAnnotationColorRed;
annotationView = pin;
}
else
