Objective-C：ScrollView左右滚动

Question

How can i scroll my scrollview to a specific point in both left & right directions.I have tried with the following piece of code but it is entering into infinite loop.

- (void)scrollViewDidScroll:(UIScrollView *)sender
{
    if (xCoord > scrollView.contentOffset.x )
    {
        scrollView.contentOffset = CGPointMake(xCoord + 160, 0);
    }
    else if(xCoord < scrollView.contentOffset.x )
    {
        scrollView.contentOffset = CGPointMake(xCoord - 160, 0);
    }

    xCoord = scrollView.contentOffset.x;
}

I just wanted scroll my scrollview by 160inches in both directions whenever user drags the screen. In my case i have few labels on scrollview, when i scroll the scrollview it has to scroll specific to label width(160) .

Try these,

1. Set your scrollview contentSize (should be higher than the frame )

   self.scrollView.contentSize = CGSizeMake(320, 900);

2. Uncheck the autoLayout checkbox in the xib

3. Assign the delegate and setScrollEnabled property to true.

  [self.scrollView setDelegate:self]; 

> [self.scrollView setScrollEnabled:YES];

Note: Only set your initial visible area as frame and total content size as contentSize .
