iPhone: UITextField End Editing event doesn't hide keyboard

Question

I want to hide keyboard on UITextField end editing event but somehow I am not able to get following code working! When I press Done button, it hides the keyboard but not when I don't press done button and move to another UITextField where I don't need keyboard but UIPickerView. Basically UIPickerView is appearing but behind the keyboard. I am resigning current UITextField on end editing event as well as on begin editing for required text fields. The begin editing code works fine if I don't have keyboard already shown for previous UITextField. Could someone please tell me what am I doing wrong?

Following sequence works:

1. Select normal UITextField and insert text, press done button (this hides keyboard)
2. Select picker UITextField (this displays picker view)

..but following doesn't:

1. Select normal UITextField and insert text

2. Select picker UITextField (the picker view is behind the keyboard as I didn't press done button for previous UITextField). Here it calls end editing but it doesn't hide keyboard!

   - (BOOL)textFieldShouldReturn:(UITextField *)textField {
       [textField resignFirstResponder];
       scrollView.contentSize = CGSizeMake(320, 750);
       [scrollView setFrame:CGRectMake(0, 0, 320, 480)];
       return YES;
    }
   
   -(void)textFieldDidEndEditing:(UITextField *)textField  
   {
       [textField resignFirstResponder];
   }
   
   - (void)textFieldDidBeginEditing:(UITextField *)textField {
       DatePicker.hidden = YES;
       CountryPickerView.hidden = YES;
   
       switch (textField.tag) {
           case 3:
               [textField resignFirstResponder];
               DatePicker.hidden = NO;
               return;
           case 6:
               [textField resignFirstResponder];
               CountryPickerView.hidden = NO;
               return;
           default:
               break;
       }
       scrollView.contentSize = CGSizeMake(320, 650);
       [scrollView setFrame:CGRectMake(0, 0, 320, 260)];
   }

You should not be relying on tags but pointers to the objects and remove [textField resignFirstResponder]; from textFieldDidEndEditing.

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField 
{ 
    if (textField == theTextFieldIDontWantKeyboardFor) {  
        [thepreviousTextField resignFirstResponder]; 
        return NO;
    }
    return YES; 
}
