如何以编程方式选择地图引脚 [英] How to select a map pin programmatically

问题描述

我很喜欢Maps Concept。

请查看附件一次。

当我点击pin我收到消息说欣赏你的笑容或任何文本.....现在我想要...当我们选择表视图时，我需要提出该引脚的消息（与该引脚的用户交互）...

我正在使用这个地图和引脚的代码。

   - （void）viewWillAppear：（BOOL ）动画
 {
 [super viewWillAppear：YES]; 
 customLocation.latitude = [casesobjc.latitude_string doubleValue]; 
 customLocation.longitude = [casesobjc.longitude_string doubleValue]; 
 MapViewAnnotation * newAnnotation = [[MapViewAnnotation alloc] initWithTitle：casesobjc.locationForMap_string andCoordinate：customLocation]; 
 [mapView addAnnotation：newAnnotation]; 
} 
  - （MKAnnotationView *）mapView：（MKMapView *）mapView viewForAnnotation :( id< MKAnnotation>）注释{
 MKPinAnnotationView * pin =（MKPinAnnotationView *）[mapView dequeueReusableAnnotationViewWithIdentifier：@annotation_ID ]; 
 if（pin == nil）{
 pin = [[MKPinAnnotationView alloc] initWithAnnotation：annotation reuseIdentifier：@annotation_ID]; 
} else {
 pin.annotation = annotation; 
} 
 pin.pinColor = MKPinAnnotationColorPurple; 
 pin.animatesDrop = YES; 
 pin.canShowCallout = YES; 
返回针; 
} 
  

现在我将显示所有的针脚，如下所示。

如何做当我们点击表格视图时，我需要显示该引脚的标题，就像我们选择一个引脚时的显示方式一样？

感谢

解决方案

您要查找的方法是 selectAnnotation：。

在您的 didSelectRowAtIndexPath 中，您必须找到与表格行相关联的注释。

pre $ [mapView selectAnnotation：foundAnnotation animated：

是]; 
  

I am new to Maps Concept.

Please find the attached image once.

when i click the "pin" i am getting message says "Admire your smile" or any text..... Now i want like... when we select the table view, i need to raise that message for that pin(with out user interaction for that pin)...

I am using below code for This maps and pins.

    -(void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:YES];
customLocation.latitude=[casesobjc.latitude_string doubleValue];
        customLocation.longitude=[casesobjc.longitude_string doubleValue];
 MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:casesobjc.locationForMap_string andCoordinate:customLocation];
[mapView addAnnotation:newAnnotation];
}
- (MKAnnotationView *) mapView: (MKMapView *) mapView viewForAnnotation: (id<MKAnnotation>) annotation {
 MKPinAnnotationView *pin = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier: @"annotation_ID"];
if (pin == nil) {
        pin = [[MKPinAnnotationView alloc] initWithAnnotation: annotation reuseIdentifier: @"annotation_ID"];
    } else {
        pin.annotation = annotation;
    }
    pin.pinColor = MKPinAnnotationColorPurple;
    pin.animatesDrop = YES;
    pin.canShowCallout=YES;
return pin;
}

Now i will show all the pins once like below.

How to do When we click on table view i need to show the title for that pin like how we show when we select a pin?

Thanks in Advance

解决方案

The method that you are looking for is selectAnnotation:.

In your didSelectRowAtIndexPath, you have to find the annotation associated with the table row.

Once you find it, you can tell it, to select it by using:

[mapView selectAnnotation:foundAnnotation animated:YES];
