contentOffset of UIScrollView

how can i get the x position of the contentOffset?

here´s my code but that throws always 0 in the log

- (void)adjustAreaScroll:(NSNotification *)notification
{
    int value = [[notification object] intValue];
    NSLog(@"adjustAreaScroll, %i", value);

    switch (value) {
        case 0:
            [topScroll setContentOffset:CGPointMake(0, 0)];
            break;
        case 1:
            [topScroll setContentOffset:CGPointMake(1024, 0)];
            break;
        case 2:
            [topScroll setContentOffset:CGPointMake(2048, 0)];
            break;
        case 3:
            [topScroll setContentOffset:CGPointMake(3072, 0)];
            break;
    }
    NSLog(@"target position -----> %i", self.topScroll.contentOffset.x);
}

     NSLog(@"Offset : %@", NSStringFromCGPoint(scrollview.contentOffset.x));

or Define as like this

CGFloat offSet= scrollview.contentOffset.x;

NSLog(@"Offset : %f", offset);

CGPointMake returns a CGPoint, which is made of CGFloats. Make the %i into %f.
