使用Google地图包

我有一个使用Google地图包的应用程序。该接口在STMapView.h文件中定义：使用Google地图包

@interface STMapView : GMSMapView

我想用我的STMapView.m观，使我的标记反应，点击，所以我也把这个功能：

-(BOOL) mapView:(GMSMapView *) mapView didTapMarker:(GMSMarker *)marker 
{ 
    NSLog(@"WHY IS THIS NOT WORKING"); 
    return YES; 
}

但是，标记只显示他们的信息，当我点击它们时，didTapMarker函数从不使用，因为NSLog没有打印到输出。我需要在别处定义函数吗？此外，一旦我得到了响应点击的功能，如何让它响应一个小的弹出视图或传递信息中的标记的新视图？

UPDATE：

STMapView.h

#import <GoogleMaps/GoogleMaps.h> 
@interface STMapView : GMSMapView 
- (void) updateShuttlesOnMap:(NSMutableData *) shuttleData; 
@end

STMapView.m

#import "STMapView.h" 
#import "STShuttleMarker.h" 
#import "STNetworkManager.h" 
#import <Foundation/Foundation.h> 

@interface STMapView() 

// This is where we will hold all our shuttles 
@property (strong, nonatomic) NSMutableDictionary *shuttleMarkers; 

// Used privately to add the shuttle stop icons to the map 
- (void) addShuttleStopsToMap; 
@end 
@implementation STMapView 

// Perform initial map setup as a View 
- (id)initWithFrame:(CGRect)frame { 
    // First run the super-class init 
    self = [super initWithFrame:frame]; 
    // Then do our setup if we actually have an object 
    if (self) { 
    // Start with room for 6 shuttles. Unsure if initial capacity helps performance or not. 
    self.shuttleMarkers = [[NSMutableDictionary alloc] initWithCapacity:6];  
    // We will handle the location stuff ourself. 
    self.myLocationEnabled = NO;  
    // Nice visuals 
    self.mapType = kGMSTypeHybrid;  
    // Move it to an initial location 
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:33.613341 
                  longitude:-84.496 
                   zoom:16.5]; 
    self.camera = camera; 
    //[self addShuttleStopsToMap]; 
    [self addPickupToMap]; 
    } 
return self; 
}

标记被在.m文件一个单独的函数以后加入。下面是该代码的小大块：

for (NSDictionary *shuttleStopMarker in shuttleStops) { 
     // Setup a set of coordinates to use for the marker 
     double mlat = [(NSNumber *)[shuttleStopMarker objectForKey:@"lat" ] doubleValue]; 
     double mlong = [(NSNumber *)[shuttleStopMarker objectForKey:@"long"] doubleValue]; 
     CLLocationCoordinate2D markerLocation = CLLocationCoordinate2DMake(mlat, mlong); 

     // Grab the meta data to use for the marker 
     NSString *shuttleStopName = (NSString *)[shuttleStopMarker objectForKey:@"name"]; 
     NSString *shuttleStopDescription = (NSString *)[shuttleStopMarker objectForKey:@"description"]; 

     // Create this marker with a position, title, and snippet/description 
     GMSMarker *marker = [GMSMarker markerWithPosition: markerLocation]; 
     marker.title = shuttleStopName; 
     marker.snippet = shuttleStopDescription; 
     marker.icon = [UIImage imageNamed:@"PassengerImage"]; 
     //[marker.map setSelectedMarker:marker]; 
     // Now add it to the map. 
     marker.map = self; 
    }

你是如何分配一个委托给'STMapView'？ – 2014-10-17 09:15:40

@AnthonyKong STMapView作为常规UIView元素，具有一些特定的增强功能。 – Becksters 2014-10-17 09:29:36

@AnthonyKong你究竟是什么意思？像我的STViewController是什么样的？ – Becksters 2014-10-17 09:30:59

所有你必须把它添加到STMapView.h的第一个文件

@interface STMapView:UIViewController <GMSMapViewDelegate>

在STMapView.m文件：

@interface STMapView() { 
    GMSMapView *mapView_; 
}

然后在viewDidLoad中，您必须像这样初始化您的地图：

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:36.4349631 
                 longitude:28.21748290000005 
                  zoom:9]; 
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera]; 
mapView_.delegate = self; 
self.view = mapView_;

，并添加一个标志无处不在，你想是这样的：

GMSMarker *marker = [GMSMarker markerWithPosition:first1]; 
    marker.title=first.title; 
    marker.icon=[UIImage imageNamed:@"hist.png"]; 
    marker.map = mapView_;

它可以正常工作，我和didTapMarker叫过。

如果您想添加一些功能来点击标记的窗口，请检查此功能。

- (void) mapView:(GMSMapView *) mapView didTapInfoWindowOfMarker:(GMSMarker *) marker 
{ 


}

还要检查这个更多的文档：
