-(void)addCutomButtonsToNavigationController:(UINavigationController *)navigationController

    UIView *customNavigationTitleView=[[UIView alloc] initWithFrame:CGRectMake(40, 0, 160, 44)]; 

    UIButton *friendRequestButton=[UIButton buttonWithType:UIButtonTypeCustom]; 
    UIButton *messagesButton=[UIButton buttonWithType:UIButtonTypeCustom]; 
    UIButton *notificationsButton=[UIButton buttonWithType:UIButtonTypeCustom]; 

    [friendRequestButton setImage:[UIImage imageNamed:@"ic_clients.png"] forState:UIControlStateNormal]; 
    [messagesButton setImage:[UIImage imageNamed:@"ic_location.png"] forState:UIControlStateNormal]; 
    [notificationsButton setImage:[UIImage imageNamed:@"ic_messsage.png"] forState:UIControlStateNormal]; 

    [friendRequestButton setFrame:CGRectMake(10, 0, 40, 40)]; 
    [messagesButton setFrame:CGRectMake(60, 0, 40, 40)]; 
    [notificationsButton setFrame:CGRectMake(110, 0, 40, 40)]; 

    [customNavigationTitleView addSubview:friendRequestButton]; 
    [customNavigationTitleView addSubview:messagesButton]; 
    [customNavigationTitleView addSubview:notificationsButton]; 

    self.navigationItem.titleView =customNavigationTitleView;
