iBooks 风格的搜索

Question

I'd like to perform multiple search operations at the same time and update UITableView as results appear, similar to the iBooks search.

The hard part is to make the table view refresh the display while search is going on.

Any suggestions will be appreciated.

Answer 1

You should search in separate thread to UI remains responsive. When search has finished and dataSource of UITableView updated you should call:

[tableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];
