使用Google Maps iOS SDK 1.4设置mapView.delegate [英] set mapView.delegate with Google Maps iOS SDK 1.4

问题描述

我刚刚从Google Maps iOS SDK 1.3.1更新到1.4，现在当我将委托设置为 mapView_.delegate = self 之类时，我的应用程序崩溃了.如果删除此行，则不会调用我的委托方法.

如何在1.4版中设置委托?
谢谢

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

推荐答案

希望您已添加googlemaps框架并正确捆绑.确保您的头文件具有

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

@interface yourViewController : UIViewController<GMSMapViewDelegate>

在实现文件中，确保仅在初始化mapView_之后设置委托.请遵循以下顺序:

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;
