使用Google地圖包

我有一個使用Google地圖包的應用程序。該接口在STMapView.h文件中定義：使用Google地圖包

@interface STMapView : GMSMapView

我想用我的STMapView.m觀，使我的標記反應，點擊，所以我也把這個功能：

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

但是，標記只顯示他們的信息，當我點擊它們時，didTapMarker函數從不使用，因爲NSLog沒有打印到輸出。我需要在別處定義函數嗎？此外，一旦我得到了響應點擊的功能，如何讓它響應一個小的彈出視圖或傳遞信息中的標記的新視圖？

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; 
}

標記被在.m文件一個單獨的函數以後加入。下面是該代碼的小大塊：

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; 
    }

你是如何分配一個委託給'STMapView'？ – 2014-10-17 09:15:40

@AnthonyKong STMapView作爲常規UIView元素，具有一些特定的增強功能。 – Becksters 2014-10-17 09:29:36

@AnthonyKong你究竟是什麼意思？像我的STViewController是什麼樣的？ – Becksters 2014-10-17 09:30:59

所有你必須把它添加到STMapView.h的第一個文件

@interface STMapView:UIViewController <GMSMapViewDelegate>

在STMapView.m文件：

@interface STMapView() { 
    GMSMapView *mapView_; 
}

然後在viewDidLoad中，您必須像這樣初始化您的地圖：

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

，並添加一個標誌無處不在，你想是這樣的：

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叫過。

如果您想添加一些功能來點擊標記的窗口，請檢查此功能。

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


}

還要檢查這個更多的文檔：

GMSMapView
