iphone - Change the speed of setContentOffset:animated:?

Question

Is there a way to change the speed of the animation when scrolling a UITableView using setContentOffset:animated:? I want to scroll it to the top, but slowly. When I try the following, it causes the bottom few cells to disappear before the animation starts (specifically, the ones that won't be visible when the scroll is done):

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:3.0];
[self.tableView setContentOffset:CGPointMake(0, 0)];
[UIView commitAnimations];

Any other way around this problem? There is a private method _setContentOffsetAnimationDuration that works, but I don't want to be rejected from the app store.

Answer 1

[UIView animateWithDuration:2.0 animations:^{
    scrollView.contentOffset = CGPointMake(x, y);
}];

It works.
