I have an App using UITableViews and fetching data from a server. I am attempting to put a UIActivityIndicatorView on the Parent UITableView, so it spins while the Child UITableView is loading. I have the UIActivityIndicatorView all hookedup through Interface Builder, etc.
-(void)spinTheSpinner {
NSLog(@"Spin The Spinner");
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
[spinner startAnimating];
[NSThread sleepForTimeInterval:9];
[self performSelectorOnMainThread:@selector(doneSpinning) withObject:nil waitUntilDone:NO];
[pool release];
}
-(void)doneSpinning {
NSLog(@"done spinning");
[spinner stopAnimating];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[NSThread detachNewThreadSelector:@selector(spinTheSpinner) toTarget:self withObject:nil];
NSMutableString *tempText = [[NSMutableString alloc] initWithString:[categoryNumber objectAtIndex:indexPath.row]];
Threads *viewController = [[Threads alloc] initWithNibName:@"newTable" bundle:nil tagval:tempText SessionID:PHPSESSID];
[self.navigationController pushViewController:viewController animated:YES];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[viewController release];
}
So, when I push the Child UITableView onto the screen, the UIActivityIndicatorView (spinner) just sits there on the Parent UITableView. If I go to the Child UITableView and then quickly go back to the Parent View, I can catch the UIActivitIndicatorView in the act of spinning. The NSLogs are showing at the correct times - when I first tap the cell in the Parent UITableView, the "Spin The Spinner" appears in the Log. 9 seconds later, I get "done spinning" in the Log, but the spinner never spins unless I pop back to the Parent UITableView in time.
Ideas of why this is not working properly?
