浏览我的iOS6应用程序并尝试修复iOS7的所有内容.在我的应用程序中,我收到错误:

-[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]

以下是此代码中的堆栈跟踪:

NSString *shareString = [NSString stringWithFormat:@"I ... %@", self.booking.venue.name];
NSArray *activityItems = [NSArray arrayWithObjects:shareString, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc]     initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]'

我正在尝试设置我的RSpec测试以使用存根而不是使用网络来进行地理编码.

我补充说:

before(:each) do
Geocoder.configure(:lookup => :test)
Geocoder::Lookup::Test.add_stub(
    "Los Angeles, CA", [{
                            :latitude    => 34.052363,
                            :longitude    => -118.256551,
                            :address      => 'Los Angeles, CA, USA',
                            :state        => 'California',
                            :state_code   => 'CA',
                            :country      => 'United States',
                            :country_code => 'US'
                        }],

)

结束

我正在使用FactoryGirl来创建测试数据,如下所示:

FactoryGirl.define do
    factory :market do
    city 'Los Angeles'
    state 'CA'
    radius 20.0
  end
end

正确地对纬度/经度进行地理编码并以纬度/经度存储.但是,当我尝试:

Market.near(params[:search])

它返回nil ..但是,如果我只是使用lookup =>:google它就像我打算一样.有没有人以前有这个工作,特别是地理编码器的近距离方法？
