finally i found that a code which will make the program crash , but i have no idea what's wrong

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Navigation logic may go here. Create and push another view controller.
    
    DataDetail *detailViewController = [[DataDetail alloc] initWithNibName:@"DataDetail" bundle:nil];
     // ...
     // Pass the selected object to the new view controller.
    
	//NSString *textTemp = [NSString stringWithFormat:@"%@",[viewArray objectAtIndex:[indexPath row]]];
	


	
    detailViewController.message = [viewArray objectAtIndex:indexPath.row];
message has been declared at datadetail.h already 


but if i add this

detailViewController.title = textTemp
// the program will crash when i back to the table view immediately 
// but the title show properly  at  datadetail.nib . 








	//[textTemp release];
	
	
	[self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];
    
}

	[self.navigationController pushViewController:detailViewController animated:YES];
    [detailViewController release];
    
}

i notice that this line is missing:
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];

and perhaps it should be more like this:


DataDetail *aDetail = [self dataDetailForIndexPath:indexPath];

DetailViewController *detailController = [[DetailViewController alloc] init];

detailController.detail = aDetail;

[self.navigationController pushViewController:detailController animated:YES];

[detailController release];
