set mapView.delegate with Google Maps iOS SDK 1.4

问题

I just updated from Google Maps iOS SDK 1.3.1 to 1.4 and now my app crashes when I set the delegate like mapView_.delegate = self. If I delete this line my delegate methods are not called.

How can I set the delegate in v 1.4?
Thanks

回答1:

Hope you have added the googlemaps framework and bundle correctly. Ensure your header file has

@interface yourViewController : UIViewController<GMSMapViewDelegate>

In your implementation file ensure that you set the delegate only after initialising your mapView_. That is below order should be followed:

mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.delegate = self;

In 1.4 there are new delegate methods. Make sure you implement the required ones.

The two new methods in 1.4 are

• mapView:willMove: and
• mapView:idleAtCameraPosition:
