Register for notification on keyboard showing: 

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; 
Then: 

- (void)removeBar 
{ 
    // Locate non-UIWindow. 
    UIWindow *keyboardWindow = nil; 
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) 
    { 
     if (![[testWindow class] isEqual:[UIWindow class]]) 
     { 
      keyboardWindow = testWindow; 
      break; 
     } 
    } 

    // Locate UIWebFormView. 
    for (UIView *possibleFormView in [keyboardWindow subviews]) 
    { 
     // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView. 
     if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) 
     { 
      for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) 
      { 
       if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) 
       { 
        [subviewWhichIsPossibleFormView removeFromSuperview]; 
       } 
      } 
     } 
     else if ([[possibleFormView description] rangeOfString:@"UIImageView"].location != NSNotFound) 
     { 
      [possibleFormView removeFromSuperview]; //remove shadow above bar. If it doesn't remove shadow then set possibleFormView's frame as CGRectZero 
     } 
    } 
}
