在Objective C中的Google Map上显示多个标记 [英] Display multiple markers on the Google Map in Objective C

问题描述

如何在iOS的Google地图上显示多个标记？
我使用了以下方法，但它不起作用。

How can I display multiple markers on the Google Map in iOS? I used the following approach, but it didn't work.

for (int i = 0; i < [array count]; i++)
{
     pointsToUse[i] = CLLocationCoordinate2DMake([[[[array objectAtIndex:0]  componentsSeparatedByString:@","] objectAtIndex:0] floatValue],[[[[array objectAtIndex:0]  componentsSeparatedByString:@","] objectAtIndex:1] floatValue]);
     [_map animateToLocation:pointsToUse[i]];
      GMSMarkerOptions *options = [[GMSMarkerOptions alloc] init];
      options.position = pointsToUse[i];
    [_map animateToLocation:pointsToUse[i]];
    [_map addMarkerWithOptions:options];
}

推荐答案

试试这个：

-(void)plotMutliplePinsonMap
{
    mapView_ = [[GMSMapView alloc]initWithFrame:CGRectMake(0, 96, 320, 450)];
    for(int i=0;i<[arrTobeShown count];i++)
    {
        double_lat = [[[arrTobeShown objectAtIndex:i]valueForKey:@"latitude"] doubleValue];
        double_long = [[[arrTobeShown objectAtIndex:i]valueForKey:@"longitude"] doubleValue];
        GMSMarker *mkr = [[GMSMarker alloc] init];
        if (double_lat !=0 && double_long!=0) 
        {        
            [mkr setPosition:CLLocationCoordinate2DMake(double_lat, double_long)];
            [mkr setTitle:[[arrTobeShown objectAtIndex:i] valueForKey:@"name"]];
            [mkr setSnippet:[[arrTobeShown objectAtIndex:i] valueForKey:@"address"]];
            [mkr setMap:mapView_];

            GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:double_lat longitude:double_long zoom:5];
        mapView_.camera=camera;
        }
    }
    [self.view addSubview:mapView_];
    [mapView_ setHidden:YES];
    [self.view layoutIfNeeded];
}
