使用Google Map sdk在ios中从GMSMapview中删除特定的GMSMarker [英] Remove particular GMSMarker from GMSMapview using Google Map sdk in ios

问题描述

我正在整合Google地图sdk。它的一切正常。但是如何在第二个出现时删除特定标记（Pin Point）（我没有使用Mapkit）

我想要下列内容：

如果我点击地图，那么现在在该位置生成一个标记针，如果我点击地图上的另一个位置，则会显示两个针，但是我想移除旧的标记针。

我也使用，

  [self.mapView clear]; 
  

但是很清楚GMSMapview的所有其他标记点。

以下是在Map上添加pin的代码：

  GMSMapView * mapView; 
 GMSMarker * currLocMarker = [[GMSMarker alloc] init]; 
 currLocMarker.map = nil; 
 [currLocMarker setTitle：NSLocalizedString（@current_location_title，nil）]; 
 currLocMarker.icon = [UIImage imageNamed：@pin_fetch_location.png]; 
 currLocMarker.position = CLLocationCoordinate2DMake（pCoordinate.latitude，pCoordinate.longitude）; 
 currLocMarker.map = self.mapView; 
  

请帮我解决这个问题.. !!

在此先感谢..：）

解决方案

是的，我找到了解决方案。
添加以下引脚：

   - （void）mapView：（GMSMapView *）mapView didTapAtCoordinate :( CLLocationCoordinate2D）坐标{
 
 pCoordinate.latitude = coordinates.latitude; 
 pCoordinate.longitude = coordinates.longitude; 
 
 [[GMSGeocoder geocoder] reverseGeocodeCoordinate：CLLocationCoordinate2DMake（coordinates.latitude，coordinates.longitude）completionHandler：^（GMSReverseGeocodeResponse * resp，NSError * error）
 {
 [currLocMarker setTitle： NSLocalizedString（@current_location_title，nil）]; 
 currLocMarker.icon = [UIImage imageNamed：@pin.png]; 
 currLocMarker.position = CLLocationCoordinate2DMake（coordinates.latitude，coordinates.longitude）; 
 currLocMarker.map = self.mapView;}];} 
  

请删除以下行如果你在上面使用过：

  GMSMarker * currLocMarker = [[GMSMarker alloc] init]; 
  

I am integrating google maps sdk. Its all work fine. But how to remove particular Marker(Pin Point) when second will appear.(I am not using Mapkit)

I want the following:

If i tap on map then one marker pin is generate at that location now if i tap on another location on map then two pins are displayed but i want to remove the old marker pin.

I also use,

[self.mapView clear];

But it was clear all other marker points from GMSMapview.

Following is the code to add pin on Map:

            GMSMapView *mapView;
            GMSMarker *currLocMarker = [[GMSMarker alloc] init];
            currLocMarker.map  = nil;
            [currLocMarker setTitle:NSLocalizedString(@"current_location_title", nil)];
            currLocMarker.icon = [UIImage imageNamed:@"pin_fetch_location.png"];
            currLocMarker.position = CLLocationCoordinate2DMake(pCoordinate.latitude, pCoordinate.longitude);
            currLocMarker.map = self.mapView;

Please help me to solve out this stuff..!!

Thanks in advance..:)

解决方案

Yes, I got that solution. Add pin like the following:

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinates {

pCoordinate.latitude =coordinates.latitude;
pCoordinate.longitude =coordinates.longitude;

[[GMSGeocoder geocoder] reverseGeocodeCoordinate:CLLocationCoordinate2DMake(coordinates.latitude, coordinates.longitude) completionHandler:^(GMSReverseGeocodeResponse *resp, NSError *error)
                {
     [currLocMarker setTitle:NSLocalizedString(@"current_location_title", nil)];
     currLocMarker.icon = [UIImage imageNamed:@"pin.png"];
     currLocMarker.position = CLLocationCoordinate2DMake(coordinates.latitude,       coordinates.longitude);
     currLocMarker.map = self.mapView;} ] ;}

Please remove the following line if you used in the above:

GMSMarker *currLocMarker = [[GMSMarker alloc] init];
