    CGRect frame = self.view.frame;

    y=textField.frame.origin.y;

    frame.origin.y =-y;

    frame.size.height +=y;

    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];

    [UIView setAnimationDuration:animationDuration];

    self.view.frame = frame;

    [UIView commitAnimations];

    y=0;

    return YES;

}

-(BOOL)textFieldShouldEndEditing:(UITextField *)textField

{

    NSTimeInterval animationDuration = 0.300000011920929;

    CGRect frame = self.view.frame;
