在iOS7中刷新UITableView scrollIndicators

Question

In iOS6 I use to have a trick to get the scroll indicators to flash in a UITableView :

- (void)didMoveToSuperview
{
    if (self.superview)
    {
        [self performSelector:@selector(flashScrollIndicators) withObject:nil afterDelay:0];
    }
}

However in iOS7 this seems to not work anymore (it worked in iOS 6), and neither does just doing: [self flashScrollIndicators] .

Has anyone figured out a way to get the scroll indicators to flash in iOS7?

Answer 1

My guess is that it's a sequence problem, ie you're populating the table after it moves to superview. To fix the issue, either:

1. Populate the table earlier in the process like viewDidLoad
2. Explicitly flash the indicators after the table has been populated
