谷歌地图在iOS中放置多个引脚

Question

我正在开发一个应用程序，在该应用程序中需要显示带有用户当前位置和检索地址的Google地图。我已经实现了该部分并且它正在工作，现在我需要找到最近的餐厅使用谷歌地方API的地方。我整合了它们，它向我展示了所有最近的餐厅。不过，我需要在该餐厅放置针脚。我使用GMSMarker来显示单个引脚，但是我需要在获取信息后显示多个引脚。以下是我的源代码。请帮助删除多个引脚。

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 

    CLLocationCoordinate2D coordinate; 

    locationManager = [[CLLocationManager alloc] init]; 
    locationManager.delegate = self; 
    locationManager.desiredAccuracy = kCLLocationAccuracyBest; 
    locationManager.distanceFilter = kCLDistanceFilterNone; 
    [locationManager startUpdatingLocation]; 
    currentLocation = [locationManager location]; 
    coordinate = [currentLocation coordinate]; 

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:coordinate.latitude longitude:coordinate.longitude zoom:15]; 

    GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectMake(0, 0, 320, 300) camera:camera]; 
    mapView.delegate = self; 

    // Creates a marker in the center of the map. 
    GMSMarker *marker = [[GMSMarker alloc] init]; 
    marker.position = CLLocationCoordinate2DMake(coordinate.latitude, coordinate.longitude); 
    marker.title = @"Current Location"; 
    marker.snippet = @"Test"; 
    marker.map = mapView; 

    [self.view addSubview:mapView];

Answer 1

for (int i=0; i<[youArray count]; i++) 
     {    
      CLLocationCoordinate2D position = CLLocationCoordinate2DMake(latitude,longitude); 
      GMSMarker *marker = [GMSMarker markerWithPosition:position]; 
      marker.title = @"Title"; 
      marker.snippet = @"Subtitle"; 
      marker.flat=YES; 
      marker.map = _mapView_results; 
     } 

这里是我用来做同样的代码。
