IOS: ActivityIndicator over UITableView... How to?

ios, uiactivityindicatorview, uitableview

Solution

You need to add the UIActivityIndicatorView to something. You can add it to a UITableView header view. To do this you will need to provide your own custom view.

...
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
[view addSubview:ac]; // <-- Your UIActivityIndicatorView
self.tableView.tableHeaderView = view;
...

Problem

i want display an activity indicator over a uitableview while it's loading data (in another thread). So in the ViewDidLoad method of the UITableViewController: ``` -(void)viewDidLoad { [super viewDidLoad]; //I create the activity indicator UIActivityIndicatorView *ac = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; [ac startAnimating]; //Create the queue to download data from internet dispatch_queue_t downloadQueue = dispatch_queue_create("PhotoDownload",NULL); dispatch_async(downloadQueue, ^{ //Download photo ....... ....... dispatch_async(dispatch_get_main_queue(), ^{ ...... ...... [ac stopAnimating]; }); }); ....... ``` Why the activity indicator don't display over the table view? How can i achieve it?
