无法从iOS分享到GooglePlus

Question

我在我的应用中处理社交套餐，并使用多个社交网络开发了共享。在实施适用于iOS的Google+ SDK时，我登录并检索了我的帐户信息，但当我开始分享时，应用程序崩溃

id<GPPNativeShareBuilder> shareBuilder = [[GPPShare sharedInstance] nativeShareDialog];
[shareBuilder setPrefillText:obj_featured.title];
UIImage *image = [self captureScreenShot];
[shareBuilder attachImage:image];
[shareBuilder open];

简单地说，我评论并测试了每一行，问题在于-open函数。 在真实设备上运行时出现错误：
