Question

In my table view I have to scroll to the top. But I cannot guarantee that the first object is going to be section 0, row 0. May be that my table view will start from section number 5.

So I get an exception, when I call:

[mainTableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:NO]; 

Is there another way to scroll to the top of table view?

Answer 1

UITableView is a subclass of UIScrollView, so you can also use:

[mainTableView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES]; 

Or

[mainTableView setContentOffset:CGPointZero animated:YES]; 

And in Swift:

mainTableView.setContentOffset(CGPointZero, animated:true) 

And in Swift 3 & above:

mainTableView.setContentOffset(.zero, animated: true)
