Question

How to make the previous “label box” disappear and be released?
I release the object but it still just creates new “label boxes” on top of “label boxes” when I tap and move.

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesMoved:touches withEvent:event];

    CGPoint nowPoint = [[touches anyObject] locationInView:self.view];
    CGPoint prevPoint = [[touches anyObject] previousLocationInView:self.view];

    CGRect RectFrame1;
    RectFrame1 = CGRectMake(nowPoint.x, nowPoint.y, 280, 30);
    UILabel *label = [[UILabel alloc] initWithFrame:RectFrame1];
    label.text = [NSString stringWithFormat:@"x %f   y %f", nowPoint.x, nowPoint.y];
    label.backgroundColor = [UIColor blackColor];
    label.textColor = [UIColor whiteColor];
    [self.view addSubview:label];
    [label release];
    //[self release];
    //[&RectFrame1 release];
}

If you want to remove it from the view use removeFromSuperview

[urlabel removeFromSuperview];
