Question

I was using the Analyze function in xcode, and I’ve fixed everything except this one.

I’m wondering what this exactly means of a “potential leak of an object allocated”, and it refers to these lines.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

self.type_prod = [[ProductType alloc] initWithNibName:@"ProductType" bundle:[NSBundle mainBundle]];

NSString *prodtitle = [product objectAtIndex:indexPath.row];
    type_prod.prodtitle = prodtitle;

 etc etc.

At the end of this void I say:

    [[self navigationController] pushViewController:type_prod animated:YES];
[type_prod release];

So why does it say there is a potential leak if I release it at the end?

Answer 1

I assume type_prod is a retained property. You need to release it in the dealloc method with self.type_prod = nil.

Also make sure the release at the end is executed in all cases. It is safer to autorelease it right away:

self.type_prod = [[[ProductType alloc] initWithNibName:@"ProductType" bundle:[NSBundle mainBundle]] autorelease];
