每个纬度经度的标记信息窗口 google 地图 ios

Question

我有经纬度和从 API 获得的其他信息，但我想动态地显示 markerinfowindow 并显示一些信息，例如姓名编号

if ([response count]>0)
     {
         NSArray *array = [response valueForKey:@"response"];

         for (int i=0; i<[array count]; i++)
         {
             [arrayLat addObject:[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"lat"]];
             [arrLong addObject:[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"longi"]];
             position = CLLocationCoordinate2DMake([[arrayLat objectAtIndex:i]floatValue],[[arrLong objectAtIndex:i]floatValue]);
             GMSMarker  *marker = [GMSMarker markerWithPosition:position];
             //marker.title = [titlearr objectAtIndex:i];
             // marker.snippet = @"Subtitle";
             marker.flat=YES;
             marker.map = mapView;
             mapView.delegate = self;
             //marker.title=[[[response valueForKey:@"response"] objectAtIndex:i] valueForKey:@"firstname"];
             marker.icon = [GMSMarker markerImageWithColor:[UIColor redColor]];
             mapView.delegate = self;
         }
     }

我有数字、名称、纬度和经度的数组，简而言之，这里有所有信息对于 markerinfowindow，我正在使用此委托方法，现在我添加静态视图，但我想根据数组

动态显示 markerinfowindow

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
{
    UIView *myview=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 170, 80)];
    myview.backgroundColor=[UIColor whiteColor];

    UILabel *lbl=[[UILabel alloc]initWithFrame:CGRectMake(10,0, 150, 28)];
    [lbl setFont:[UIFont fontWithName:@"Helvetica" size:13.0]];
    lbl.text=@"3.Gregor cleasgance";
    lbl.font = [UIFont boldSystemFontOfSize:13.0f];
    lbl.textColor=[UIColor blackColor];
    [myview addSubview:lbl];


    UILabel *lbl2=[[UILabel alloc]initWithFrame:CGRectMake(10,24, 100, 20)];
    [lbl2 setFont:[UIFont fontWithName:@"Helvetica" size:13.0]];
    lbl2.text=@"Monday 07/02";
    lbl2.textColor=[UIColor darkGrayColor];
    [myview addSubview:lbl2];

    UILabel *lbl3=[[UILabel alloc]initWithFrame:CGRectMake(120,24, 100, 20)];
    [lbl3 setFont:[UIFont fontWithName:@"Helvetica" size:13.0]];
    lbl3.text=@"14:00h";
    lbl3.textColor=[UIColor darkGrayColor];
    [myview addSubview:lbl3];

    UILabel *lbl4=[[UILabel alloc]initWithFrame:CGRectMake(0,0, 7, 80)];
    lbl4.backgroundColor=[UIColor colorWithRed:255.0/255.0 green:192.0/255.0 blue:1.0/255.0 alpha:1.0];
    [myview addSubview:lbl4];
    return myview;

}

Answer 1

您可以使用 GMSMarker

的属性 userData

示例：您有这样的数据

json = [{"id":1,"name":"demo", "city":"BOTAD"},{"id":2,"name":"demo2", "city":"SURAT"}]

如果您想显示 BOTAD 的数据，请将 userData 设置为

GMSMarker *marker = [[GMSMarker alloc] init];
marker.userData = [json objectAtIndex:0];

之后你可以在像

这样的委托方法下得到它

- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
{
    NSDictionary *data = marker.userData;

    return mapView;
}

现在很容易从字典中获取城市和姓名等数据，您可以在标签上设置文本。
