在地图视图上点击注释时将数据传递给 detailView [英] Pass data to detailView when annotation tapped on mapview

问题描述

我有一个地图视图，有 10 个商店位置的数据来自网络服务.我只想推送到我的详细信息视图以显示点击商店的地址、电话和其他信息.

I have a map view and there are 10 store locations which data comes via webservice. I just want to push to my detail view to show address, telephone and other informations of the clicked store.

当用户点击或触摸 mapkit 上的注释时，我需要将数据传递到我的 detailview.我的 mapview 中有 10 个注释，首先我想知道，我如何理解或如何获取单击了哪个注释的 annotationID?

I need to pass data to my detailview when user tapped or touch up inside to a annotation on mapkit. There are 10 annotations in my mapview and first I want to know, how can I understand or how can I get the annotationID of which annotation is clicked?

这是我返回pins的方法

this is the method I return pins

 - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{

    if ([annotation isKindOfClass:[MKUserLocation class]]) return nil;

    static NSString* AnnotationIdentifier = @"AnnotationIdentifier";

    MKPinAnnotationView* pinView = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];

     pinView.animatesDrop=YES;
     pinView.canShowCallout=YES;
     pinView.pinColor=MKPinAnnotationColorPurple;

     UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
     [rightButton setTitle:annotation.title forState:UIControlStateNormal];

     [rightButton addTarget:self
     action:@selector(showDetails:)
     forControlEvents:UIControlEventTouchUpInside];

     pinView.rightCalloutAccessoryView = rightButton;

    return pinView;
}
   /* and my action method for clicked or tapped annotation: */

 - (IBAction)showDetails:(id)sender{

      NSLog(@"Annotation Click");

      [[mtMap selectedAnnotations]objectAtIndex:0];
      magazaDetayViewController *detail = [[magazaDetayViewController 
      alloc]initWithNibName:@"magazaDetayViewController" bundle:nil];

      detail.sehir=@"";
      detail.magazaAdi=@"";
      detail.adres=@"";
      detail.telefon=@"";
      detail.fax=@"";
      [self.navigationController pushViewController:detail animated:YES];

 }

如果我只能获得点击的注释索引，我可以用我的数组填充细节属性.如果这是不可能的，还有其他方法吗?

if i can just get the clicked annotation index no i can fill detail properties with my array. if this is impossible is there any other way to do it?

推荐答案

首先在你的 annotaion view delegat make a button to go in detail view like bellow:

First in your annotaion view delegat make a button to go in detail view like bellow:

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{

MKPinAnnotationView *mypin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"current"];
mypin.pinColor = MKPinAnnotationColorPurple;
mypin.backgroundColor = [UIColor clearColor];
UIButton *goToDetail = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
mypin.rightCalloutAccessoryView = myBtn;
mypin.draggable = NO;
mypin.highlighted = YES;
mypin.animatesDrop = TRUE;
mypin.canShowCallout = YES;
return mypin;
}

现在，每当 annotationView 中的按钮被点击时，请使用以下委托，将从您可以轻松获取点击哪个特定 annotaion 的按钮的位置调用以下委托

Now use the following delegate whenever the button in annotationView will get tapped the following delegate will be called from where you can easly get which particular annotaion's button is tapped

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view 
 calloutAccessoryControlTapped:(UIControl *)control
{
annotation *annView = view.annotation;
detailedViewOfList *detailView = [[detailedViewOfList alloc]init];
detailView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
detailView.address = annView.address;
detailView.phoneNumber = annView.phonenumber;
[self presentModalViewController:detailView animated:YES];
}

这里 annotaion 是一个导入 MKAnnotaion.h 的类，address 和 phonenumber 是 annotaion 类的属性，你可以做更多，而 detailView 类的 address 和 phoneNumber 属性很强.这样你就可以传递值了.希望能帮到你！

here annotaion is a class importing MKAnnotaion.h and address and phonenumber are properties of annotaion class you can make many more while the address and phoneNumber properties of detailView class are strong. So that you can pass values. Hope this will help you!
