Ah, reasonably better! Now I have:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if(dvController == nil)
{
theaterDetailController *aController = [[theaterDetailController alloc] initWithNibName:@"theaterDetailView" bundle:nil];
self.dvController = aController;
[aController release];
}
[dvController setTableData:[items objectAtIndex:indexPath.row]];
[dvController updateRowNumber:indexPath.row];
[[self navigationController] pushViewController:dvController animated:YES];
}
and the method:
-(void)setTableData:(NSDictionary *)myTheater {
NSLog(@"myTheater is %@", myTheater);
}
It compiles and runs, but the object myTheater is empty according to
NSLog. Is there something obvious that I'm doing wrong?
