How to include a button in InfoWindow - ios

Question

I followed this tutorial on how to add custom info window to a google map marker,
in the UIView I've added a button and created an IBAction but when I click on it nothing happen
my infoWindow view code looks like this
.h
#import <UIKit/UIKit.h>
#import "Details.h"
#interface MarkerInfoWindowView : UIView
#property (weak, nonatomic) IBOutlet UIImageView *imageView;
#property (weak, nonatomic) IBOutlet UILabel *label1;
#property (weak, nonatomic) IBOutlet UILabel *label2;
#property (weak, nonatomic) IBOutlet UIButton *btn1;
- (void) initializeWithDetails:(Details*)p_details;
#end
.m
#import "MarkerInfoWindowView.h"
#implementation MarkerInfoWindowView
- (void) initializeWithDetails:(Details*)p_details
{
if(self != nil)
{
self.imageView.image = [UIImage imageWithContentsOfFile:p_basicDetails.imageURL];
self.label1.text = p_details.l1;
self.label2.text = p_details.l2;
}
}
-(IBAction) btn1_Clicked:(id)sender
{
NSLog(#"button clicked");
}
#end
and then in my view controller of the main screen and map
-(MarkerInfoWindowView*) customInfoWindow
{
if(_customInfoWindow == nil)
{
_customInfoWindow = [[[NSBundle mainBundle] loadNibNamed:#"MarkerInfoWindowView" owner:self options:nil] objectAtIndex:0];
}
return _customInfoWindow;
}
- (UIView *)mapView:(GMSMapView *)p_mapView markerInfoWindow:(GMSMarker *)p_marker
{
Details* temp = [[Details alloc] init];
temp.l1 = #"L1";
temp.l2 = #"L2";
temp.imageURL = #"someImage.jpg";
[self.customInfoWindow initializeWithDetails:temp];
return self.customInfoWindow;
}
any suggestions?

Answer 1

first the reason for the button not being clicked is because google-maps takes the UIView and renders it as an imageView so the button is part of an image and of course not clickable.
the solution is to add a UIView and handle on your own the hide/show and positioning.
instead of using
(UIView *)mapView:(GMSMapView *)p_mapView markerInfoWindow:(GMSMarker *)p_marker
i used didTapMarker and returned YES;
