iOS Mapkit 自定义标注
这是一个示例自定义标注,我想要获得类似的样式。我正在考虑继承 MKAnnotation 但我不知道如何启动它,而且我不知道标注的设计是否可以被覆盖。
任意如何使用 ui 控件实现此自定义标注的想法 里面?
编辑:这是我的代码,来自类似的 StackOverflow 答案:
- (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
{
UIImage *img = [UIImage imageNamed:@"default_thumb.png"];
MKAnnotationView *annotationView =
[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
annotationView.canShowCallout = YES;
annotationView.image = img;
annotationView.draggable = YES;
/*
// change left accessory view button with image
UIImageView *leftAccView = [[UIImageView alloc] initWithImage:img];
annotationView.leftCalloutAccessoryView = leftAccView;
//include a right button to show more info
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:@selector(calloutSubMenu:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
annotationView.rightCalloutAccessoryView = rightButton;
*/
return annotationView;
}
return nil;
}
// Customize accessory view
- (void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
[mapview deselectAnnotation:view.annotation animated:YES];
PopOverCallout *popOverCallout = [[PopOverCallout alloc]init];
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:popOverCallout];
self.annotationPopoverController = popOver;
popOver.popoverContentSize = CGSizeMake(500, 500);
[popOver presentPopoverFromRect:view.bounds inView:view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
?
(void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
每当触摸 pin 时都应该调用以显示标注,对吗 但发生的情况是显示空白的常规标注。我可能做错了什么?
顺便说一句:UIViewController 子类在它的 XIB 上只有一个标签,几乎是空白的。
Here's a sample custom callout that I'd want to get a similar style of. I was thinking of inheriting from MKAnnotation but I'm lost how to start it and I don't know if the callout's design could be overridden.
Any ideas how to implement this custom callout with ui controls inside?
EDIT: Here's my code from following the similar StackOverflow answer:
- (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
{
UIImage *img = [UIImage imageNamed:@"default_thumb.png"];
MKAnnotationView *annotationView =
[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
annotationView.canShowCallout = YES;
annotationView.image = img;
annotationView.draggable = YES;
/*
// change left accessory view button with image
UIImageView *leftAccView = [[UIImageView alloc] initWithImage:img];
annotationView.leftCalloutAccessoryView = leftAccView;
//include a right button to show more info
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:@selector(calloutSubMenu:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
annotationView.rightCalloutAccessoryView = rightButton;
*/
return annotationView;
}
return nil;
}
// Customize accessory view
- (void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
[mapview deselectAnnotation:view.annotation animated:YES];
PopOverCallout *popOverCallout = [[PopOverCallout alloc]init];
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:popOverCallout];
self.annotationPopoverController = popOver;
popOver.popoverContentSize = CGSizeMake(500, 500);
[popOver presentPopoverFromRect:view.bounds inView:view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
The
(void)mapView:(MKMapView *)mapview annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
should be called whenever the pin is touched to show the callout right? but what happens is that a blank regular callout is shown. What might I be doing wrong?
BTW: the UIViewController subclass only has a label on it's XIB and is pretty much blank.

小睡几分钟后找到了答案。
使用 this 作为指南,我只需要覆盖
它显示注释标注。再次感谢安娜女士的回答。
Found out the answer after a few mins of nap.
using this as the guide, I just needed to override
which shows the annotation callout. Thanks again for the answer, Ms. Anna.
