iOS compile error: No visible @interface for 'CDViewController' declares the selector

Since I switched my iOS project to ARC, I keep getting this compiler error:

No visible @interface for 'CDViewController' declares the selector 'setUseAgof:'

In this line:

[self.viewController setUseAgof:false];

In this file:

AppDelegate.m

#import "AppDelegate.h"
#import "MainViewController.h"
#import <Cordova/CDVPlugin.h>
#import "NSString+MD5.h"

@implementation AppDelegate

@synthesize window, viewController;

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    // (...)
    [self.viewController setUseAgof:false]; // <-- HERE
    // (...)

    return YES;
}

@end

Although the method is definitely defined:

MainViewController.h

#import <Cordova/CDVViewController.h>
#import <ADTECHMobileSDK/ADTECHMobileSDK.h>

@interface MainViewController : CDVViewController <ATInterstitialViewDelegate>{
    ATInterstitialView *interstitial;
}
- (void)setUseAgof:(BOOL)useAgofParam;
@end

@interface MainCommandDelegate : CDVCommandDelegateImpl
@end

@interface MainCommandQueue : CDVCommandQueue
@end

MainViewController.m

#import "MainViewController.h"

@interface MainViewController()
    - (void)setUseAgof:(BOOL)useAgofParam;
@end

@implementation MainViewController

BOOL useAgof = true;

- (void)setUseAgof:(BOOL)useAgofParam
{
    NSLog(@"1.) Setting useAgof = %d", (int)useAgofParam);
    useAgof = useAgofParam;
}

I don't get it. What's wrong?

Update:

AppDelegate.h

#import <UIKit/UIKit.h>
#import <Cordova/CDVViewController.h>
#import <INFOnlineLibrary/INFOnlineLibrary.h>

@interface AppDelegate : NSObject <UIApplicationDelegate>{}

@property (nonatomic, strong) IBOutlet UIWindow* window;
@property (nonatomic, strong) IBOutlet CDVViewController* viewController;

@end

viewController seems to be declared as pointer of CDVViewController. You are calling a method which is part of MainViewController the class derived from CDVViewController. Method being called is part of derived class and not the base class, hence make viewController pointer of MainViewController instead.

Make sure the viewController property in your AppDelegate has a type of CDVViewController * rather than UIViewController *.
