IOS UIScrollView与UIPageController配合使用

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat pageWidth = scrollView.frame.size.width;
int currentPage = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
self.futurePageControl.currentPage = currentPage;

}

- (IBAction)pageChange:(id)sender {
CGRect frame = self.futureWeatherScroll.frame;

frame.origin.x= frame.size.width * self.futurePageControl.currentPage;

frame.origin.y= 0;

[self.futureWeatherScroll scrollRectToVisible:frame animated:YES];
}
