Using ReactiveCocoa to get rid of the scroll view delegate, to update a UIPageControl's currentPage as you scroll.
CGFloat pageWidth = CGRectGetWidth(self.scrollView.frame);
RAC(self.pageControl, currentPage) = [RACObserve(self.scrollView, contentOffset) map:^id(NSValue *value) {
CGPoint contentOffset = [value CGPointValue];
NSUInteger page = floor((contentOffset.x - pageWidth / 2) / pageWidth) + 1;
return @(page);
}];

How to programmatically scroll a tableview to the top, then run a block when it's done animating. #ReactiveCocoa
[[[RACObserve(self.tableView, contentOffset)
filter:^BOOL(NSValue *contentOffset) {
CGPoint point = [contentOffset CGPointValue];
return point.y == 0.0f;
}]
take:1]
subscribeCompleted:^{
// This block gets executed when the tableview has scrolled to top
}];
