static const float gap = 5; //gap between the top of keyboard and the control
//Find the controls absolute position in the 320*480 window - it could be nested in other views
CGPoint absolute = [activeField.superview convertPoint:activeField.frame.origin toView:nil];
//NSLog(#"Keyborad Shown %f : %f",absolute.y,(keyboardHeight + gap);
if (absolute.y > (keyboardHeight + gap)) {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3f]; //this is speed of keyboard
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CGRect bkgndRect = activeField.superview.frame;
bkgndRect.size.height += kbSize.height;
[activeField.superview setFrame:bkgndRect];
[scrollview setContentOffset:CGPointMake(0.0, activeField.frame.origin.y-92) animated:YES];

NSValue* aValue = [info objectForKey:UIKeyboardFrameEndUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
// Reset the height of the scroll view to its original value
CGRect viewFrame = [scrollview frame];
viewFrame.size.height += keyboardSize.height;
