Move a view when scrolling in UITableView

Question

I have a UIView with a UITableView below it:

Answer 1

I know this post in very old. I tried above solutions but neither worked for me for tried my own, hopefully it can help you. This scenario is pretty common, as apple suggested not to use TableViewController inside any ScrollView because the compiler will confused as in whom to respond becuase it will be getting two delegate call back - one from ScrollViewDelegate and another from UITableViewDelegate.

Instead we can use ScrollViewDelegate and disable the UITableViewScrolling.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    CGFloat currentOffSetY = scrollView.contentOffset.y;
    CGFloat diffOffset = self.lastContentOffset - currentOffSetY;

    self.scrollView.contentSize = CGSizeMake(self.scrollView.contentSize.width, 400 + [self.tableView contentSize].height);

    if (self.lastContentOffset < scrollView.contentOffset.y) {
        tableView.frame = CGRectMake(tableView.frame.origin.x, tableView.frame.origin.y , tableView.frame.size.width,  tableView.size.height - diffOffset);
    }

    if (self.lastContentOffset > scrollView.contentOffset.y) {
        tableView.frame = CGRectMake(tableView.frame.origin.x, tableViewframe.origin.y, tableViewframe.size.width,  tableView.frame.size.height + diffOffset);
    }

    self.lastContentOffset = currentOffSetY;
}

Here lastContentOffset is CGFloat defined as property

The View Heirarchy is as follows: ViewController --> View contains ScrollView (whose delegate method is defined above) --> Contain TableView.

By the above code we are manually increasing and decreasing the height of the table view along with the content size of ScrollView.

Remember to disable the Scrolling of TableView.
