xcode：以下教程，但“ subViewOneController”未声明错误

Question

So I'm new to programming for the iPhone and I'm trying this new tutorial here: http://theappleblog.com/2009/04/15/iphone-dev-sessions-create-a-navigation-based-application/

When I build the project, under the: RootViewController.m

I get a 'subViewOneController' undeclared error at the first line:

// allocate a set of views and add to our view array as a dictionary item

SubViewOneController *subViewOneController = [[SubViewOneController alloc] init];

subViewOneController.title = @"Subview One";

What does the error mean? and where should I look to make sure names are matching?

Thanks, Matt

您需要确保存在一个名为SubViewOneController的类，并且要在RootViewController.m导入其标头（ SubViewOneController.h ）。
