copied!<p>Hard to say with that piece of code you gave. And in fact, if you're saying, that you have a project, where everything is working under the same conditions, then obviously the conditions aren't the same :) I couldn't reproduce the issue, but here are some assumptions for 2 cases:</p> <ol> <li><p>Creation of UIScrollView with nib.</p> <ul> <li>Just don't forget to create IBOutlet and to bound it to the scrollView element in nib. In a simple view based application just after that I got scrollView working as you wished in animated: both YES and NO. But to make work </li> </ul> <p><code>-(void)scrollViewDidScroll:(UIScrollView *)sender;</code> you must set the delegate:</p></li> </ol> <p><code>yourScrollView.delegate = self;</code></p> <p>where 'self' is class, where you have your scrollViewDidScroll function; btw this class must conform to the 'UIScrollViewDelegate' protocol.</p> <p>2.Creation of UIScrollView object manually.</p> <ul> <li><p>here the idea is basically the same, so I'll just provide some simple code:</p> <pre><code>-(void) creatingScrollView { UIScrollView *newScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(20, 5, 280, 44)]; newScroll.pagingEnabled = YES; newScroll.showsVerticalScrollIndicator = NO; newScroll.showsHorizontalScrollIndicator = NO; // ... some subviews being added to our scroll view newScroll.delegate = self; [self.view addSubview:newScroll]; [newScroll release]; } </code></pre></li> </ul> <p>This works for me. Hope this is helpful.</p>
