Can't access public methods of NSObject from AppDelegate
===

I have created this NSObject subtype class:


    #import <Foundation/Foundation.h>
    #import "SQLiteManager.h"
    
    @interface clickEventManagement : NSObject{
        
        SQLiteManager *dbManager;
        
        NSURLConnection *adsconnection;
        
        NSMutableData *responseData;
        
    }
    
    @property (strong, nonatomic) NSURLConnection *adsconnection;
    
    -(void) insertClickAdd:(int)zona;
    
    -(void) insertPrintAdd:(int)zona;
    
    -(NSArray*) loadClicks;
    
    @end


And I have declared it in the AppDelegate.h:


    #import "clickEventManagement.h"
    
    @interface AppDelegate : NSObject <UIApplicationDelegate, AVAudioSessionDelegate>
    
    {
        
        BOOL firstRun;
        
        AVPlayer *player;
        
        clickEventManagement *clickEvent;
    
        
    }
    
    @property (strong, nonatomic) clickEventManagement *clickEvent;

But clickEventMangement methods are not available when I try to implement them in the - (void)applicationDidEnterBackground:(UIApplication *)application delegate. Same class in other view controllers, declared in the same way, are available.

Thanks!
