Strange behaviour of UITableView scrollToRowAtIndexPath:

I have to set an initial scroll position of my UITableView to a row other than the first one (for example, the first row of the second section).

In my view controller's viewDidLoad I write:

- (void)viewDidLoad
{
    // self.view is a 开发者_JAVA技巧container view, not UITableView
    [super viewDidLoad];
    [table scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:1]
       atScrollPosition:UITableViewScrollPositionTop animated:NO];
}

When the screen loads, the scroll position is not set immediately. Otherwise, when the animated parameter is set to YES, the position is set immediately without any animation. What's going on?

What's the correct way to set initial row position for UITableView?

Best place should be ViewDidAppear. Moreover, you should invoke scroll method in cellWillDisplay to make sure. Remember to check indexPath before invoking scroll method

Just a shot in the dark, but have you tried to put this code into viewDidAppear{}?

This won't work in viewDidLoad or viewWillAppear since the table most likely haven't been populated by then (at least it wasn't in my case)

Try putting it in an NSTimer instead once your table loads and calling it then.

As an aside, I quickly put this code (with animation) into a nav bar button item and it worked very well after the table was finished loading.
