   // Find first responder
   UIView *inputView = [self findFirstResponder];
   if (inputView != nil) {
       // Re assign the focus
     //        [inputView resignFirstResponder];   // <-- the two lines cause a dead loop 
  // after commented the above line, it works well on iOS7, iOS5 (I have no other devices)
          [inputView becomeFirstResponder];
   }

    - (void)inputKeyboardWillShow:(NSNotification *)notification
   {
       CGRect keyboardEndFrameWindow = [notification.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];

   CGRect keyboardBeginFrameWindow = [notification.userInfo[UIKeyboardFrameBeginUserInfoKey] CGRectValue];
