Question

A fairly short question, How can I load a UIActivityIndicatorView for say 0.5 seconds from when the view loads?

I have had a look around but most tutorials are using the webview where an if statment is created where (webview.loading) is used to define the length of the animation etc..
so i am just woundering how to do this when ever the view loads for .5 second.

Currently I have a method that centers the previously selected cell which I would like the indicator to last untill this is done.

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
[self performSelector:@selector(scrollToRowAtIndexPath) withObject:nil afterDelay:1.0];
}

- (void)scrollToRowAtIndexPath
{    
    [self.tableView reloadData];
    [self.tableView scrollToRowAtIndexPath:oldCheckedIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
}

Maybe some like that helps:

-(void)viewDidLoad
{
    [super viewDidLoad];

    //... all your previous charge.

    UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];

    activity.hidesWhenStopped = YES;

    activity.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin |
        UIViewAutoresizingFlexibleHeight |
        UIViewAutoresizingFlexibleLeftMargin |
        UIViewAutoresizingFlexibleRightMargin |
        UIViewAutoresizingFlexibleTopMargin |
        UIViewAutoresizingFlexibleWidth;

    [yourTable addSubview:activity];

    [activity startAnimating];

    [activity performSelector:@selector(stopAnimating) withObject:nil afterDelay:0.5];

    [activity release];
}
