I'm trying to have an info box, same one as the standard for markers, to appear when a my polyline is tapped. I've gotten a NSLog to output when the line is tapped, but now I need to have the infobox appear instead of the NSLog. I've seen some Javascript examples but no objective c ones.

Check the Events guide from the iOS Maps tutorial.
Here's a snippet in Objective-C:
- (void)loadView {
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:1.285
longitude:103.848
zoom:12];
GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView.delegate = self;
self.view = mapView;
}
#pragma mark - GMSMapViewDelegate
- (void)mapView:(GMSMapView *)mapView
didTapAtCoordinate:(CLLocationCoordinate2D)coordinate {
NSLog(#"You tapped at %f,%f", coordinate.latitude, coordinate.longitude);
}
Here's an SO thread demonstrating the use of GMSMapViewDelegate:
1.conform to the GMSMapViewDelegate protocol.
#interface YourViewController () <GMSMapViewDelegate>
// your properties
#end
2.set your mapView_ delegate.
mapView_.delegate = self;
3.implement the GMSMapViewDelegate method
- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker {
// your code
}
Addition: marker.userData is useful. you can set your needed data into it and use it in - mapView:didTapInfoWindowOfMarker:
For some reason, I can't seem to get tap and longtap and all the other delegate events to work in my simulator. I think I installed everything correctly because the map shows up on the screen, with a custom button click I can put a marker on the map, but it will not recognize the delegate events. Am I doing something wrong???

The only thing that works is the IBAction. Also my location and compass buttons do not show up. Any ideas of why it's not working? I declared the delegates...
You need to set all properties after the object initialization.
- (void)viewDidLoad {
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86 longitude:151.20 zoom:15];
mapView = [GMSMapView mapWithFrame:CGRectMake(0, 0, self.mapContainer.frame.size.width, self.mapContainer.frame.size.height) camera:camera];
mapView.delegate = self;
mapView.myLocationEnabled = YES;
mapView.settings.myLocationButton = YES;
mapView.settings.compassButton = YES;
[self.mapContainer addSubview:mapView];
}
I implementing Google maps with factory design pattern. But map is not displayed when i load the map view. When i implemented the same without using factory pattern, i could get it loaded successfully. please help me to fix this issue. Below shown is the code.

marker.map = mapView_;
return mapView_;
}
MapBuilderDelegate
#protocol MapBuilderDelegate <NSObject>
-(void)initMapWithApiKey:(NSString*)apiKey;

is the problem with the view or is the map configuration? I dont see where the frame is specified. below i've added a setframe in your viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
id<MapBuilderDelegate> mapBuilder=[MapBuilderFactory mapWithName:GoogleMaps];
[mapBuilder initMapWithApiKey:kGoogleMapsApiKey];
UIView *mapView= [mapBuilder mapView];
[mapView setFrame:CGRectMake(0.0, 0.0, 320.0, 500.0)];
[self.view addSubview:mapView];
}
I am using the Google Maps iOS API. None of the delegate methods are firing. How do I make them work?

I think you are setting the delegate property to early
try this :
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:10
longitude:10
zoom:15];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
mapView_.delegate = self;
self.view = mapView_;
Set the delegate in the ViewDidLoad
I am making an iPhone application that uses a GMSMapView and I want to be able to add a toolbar on top of the map. This is my code:

#end
#implementation MapViewController
{
GMSMapView *mapView_;
id<GMSMarker> myMarker;
}

{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {

}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)back:(id)sender
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
// You don't need to modify the default initWithNibName:bundle: method.
- (void)loadView
{
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:30.616083 longitude:-96.338908 zoom:13];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
mapView_.delegate = self;
self.view = mapView_;
GMSMarkerOptions *options = [[GMSMarkerOptions alloc] init];
options.position = CLLocationCoordinate2DMake(30.616083, -96.338908);
options.title = #"College Station";
options.snippet = #"Texas";
[mapView_ addMarkerWithOptions:options];
}
#pragma mark - GMSMapViewDelegate
- (void)mapView:(GMSMapView *)mapView
didTapAtCoordinate:(CLLocationCoordinate2D)coordinate
{
[myMarker remove];
NSLog(#"You tapped at %f,%f", coordinate.latitude, coordinate.longitude);
GMSMarkerOptions *marker = [[GMSMarkerOptions alloc] init];
marker.position = CLLocationCoordinate2DMake(coordinate.latitude, coordinate.longitude);
marker.title = #"Tap Event";
// (icon for marker) marker.icon = [UIImage imageNamed:#"house"];
myMarker = [mapView_ addMarkerWithOptions:marker];
}
#end
In my storyboard i have a toolbar but I do not know how to get it to be displayed over the GMSMapView. Im new to iOS and have searched for solutions online but haven't had any luck with GMSMapView.
Because you set the view to the mapView_, the view made in StoryBoard is overriden. I've added a toolbar with an Segmented Control and an button using the following code:
CGRect screenBounds = [[UIScreen mainScreen] bounds];
UINavigationBar *navBar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, screenBounds.size.width, 44)];
UINavigationItem *navItems = [[UINavigationItem alloc]init];
UIBarButtonItem *barButtonRight = [[UIBarButtonItem alloc]initWithTitle:#"" style:UIBarButtonItemStylePlain target:self action:#selector(SettingsButtonPressed)];
UISegmentedControll *segControl = [[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects:#"Opt1",#"Opt2",#"Opt3", nil]];
UIImage *imageSettings= [UIImage imageNamed:#"36-toolbox.png"];
[segControl setSegmentedControlStyle:UISegmentedControlStyleBar];
[segControl setSelectedSegmentIndex:0];
[segControl setFrame:CGRectMake(10, 5, 150, 32)];
[segControl addTarget:self action:#selector(KiesVC:) forControlEvents:UIControlEventValueChanged];
[barButtonRight setImage:imageSettings];
[navItems setRightBarButtonItem:barButtonRight];
[navItems setTitleView:segControl];
[navBar setItems:[NSArray arrayWithObject:navItems] animated:NO];
You then add the toolbar by calling :
[self.view addSubview:navBar];
Hope it helps
