Obj-C - Google Maps SDK 获取所选标记的数据？

Question

我正在尝试使用以下代码获取所选标记的数据：

-(void)viewDidLoad {

 NSMutableDictionary *viewParams3 = [NSMutableDictionary new];
     [viewParams3 setValue:@"breweries" forKey:@"view_name"];
     [DIOSView viewGet:viewParams3 success:^(AFHTTPRequestOperation *operation, id responseObject) {
         
         self.breweryLocations = [responseObject mutableCopy];
      
      
         int index = 0;
         
         for (NSMutableDictionary *brewInfo in self.breweryLocations) {
         
         NSString *location = brewInfo[@"address"];
         NSString *userNames = brewInfo[@"node_title"];
         NSString *firstRemoved = [userNames stringByReplacingOccurrencesOfString:@"&#039;" withString:@""];

          
         NSString *userBio = brewInfo[@"body"];
         

          
          CLGeocoder *geocoderFriend = [[CLGeocoder alloc] init];
          [geocoderFriend geocodeAddressString:location
            completionHandler:^(NSArray* placemarks, NSError* error){
            if (placemarks && placemarks.count > 0) {
           CLPlacemark *topResult = [placemarks objectAtIndex:0];
             MKPlacemark *placemark = [[MKPlacemark alloc] initWithPlacemark:topResult];
      
                
                
                CLLocationCoordinate2D position = placemark.coordinate;
                GMSMarker *marker = [GMSMarker markerWithPosition:position];
                marker.title = firstRemoved;
                marker.icon = [UIImage imageNamed:@"brewIconMax"];
                marker.map = self.mapView;
                marker.userData = self.breweryLocations;
               
                marker.map.selectedMarker.zIndex = index + 1;
                                                                               }
          
          }
                                                        ];
          
          }
      
         
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         NSLog(@"Failure: %@", [error localizedDescription]);
     }];


}

- (BOOL) mapView: (GMSMapView *)mapView didTapMarker:(GMSMarker *)marker
{

   self.venueCategory.text = marker.userData[mapView.selectedMarker.zIndex][@"type"];

}

也就是说，这行代码

self.venueCategory.text = marker.userData[mapView.selectedMarker.zIndex][@"type"];

returns 来自数组中第一个字典的数据，无论我点击哪个标记（zIndex 始终返回为 0）。我似乎无法在任何地方找到正确的代码来获取所选标记的数组数据。

知道该行应该是什么样子吗？

Answer 1

我不清楚“类型”是否是啤酒厂位置字典的一个元素，所以我在这里进行一些猜测。

我建议将 marker.userData 设置为 brewInfo 字典，而不是整个 breweryLocations 数组。

marker.userData = brewInfo;

然后从 brewInfo 字典中获取“类型”。

self.venueCategory.text = marker.userData[@"type"];
