Error will not go away, but not even anything on the line

Why will 开发者_开发问答this error not go away? Anybody know? It says build successful, but this line remains, even after closing.

It looks like you're trying to declare an ivar outside of the ivar block. This would be the SwitchingViews *switchingViews; line. That is almost certainly the source of the error.

Your class definition should look like:

@interface YourAwesomeClass : NSObject 
{
    SwitchingViews *switchingViews;
}
