UITextField resignFirstResponder无法正常工作？

Question

I've double checked all the connections in the nib file. My code -

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"iphone_bg_login.png"]];
    self.title = @"Login screen";
    loginTxt = [[UITextField alloc] init];
    pwdText = [[UITextField alloc] init];
    loginFailedTxt = [[UILabel alloc] init];
    loginBtn = [[UIButton alloc] init];
    navAppDelegate = (NavAppDelegate *)[[UIApplication sharedApplication] delegate]; 
    navAppDelegate.navController.navigationBarHidden = YES;
    //NSArray *subVs = (NSArray *) [self.view subviews];
    [super viewDidLoad];
}

I've used a subclass of UIView (UIControl) and added all the UI elements to it in the Interface builder.The UIControl's touchDown method is connected to backgroundTap method.

-(IBAction) backgroundTap:(id) sender {
    [loginTxt resignFirstResponder];
    [pwdText resignFirstResponder];
    //[[UIApplication sharedApplication] becomeFirstResponder];
        //[sender resignFirstResponder];
} 

So the keyboard isn't removed like it's supposed to. Not sure why.

Thanks for the help! Teja.

DyingCactus has pointed to your error. You're replacing the NIB-version of the control with a completely different control, losing your pointer to the one in the NIB. When you call resignFirstResponder , you're calling it on your duplicate object, not the one that's actually on the screen. Get rid of the alloc and init calls for things wired in the NIB.
