Question

i m parsing a json file.the logic goes like this, if there is no data in the variable named boy.it got to enter the if loop and if there is data it got to enter the else part.but the problem is even if the variable boy is empty(which shows empty in the console) the loop still enters the else part..cud u guys help me out..below is the code..

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.
NSDictionary *boy=[url objectAtIndex:indexPath.row];
NSLog(@"the boy value:%@",boy);
if (boy == NULL) 
{
Secondetailview *detailViewController1 = [[Secondetailview alloc] initWithItem:boy];    
[self.navigationController pushViewController:detailViewController1 animated:YES];
[detailViewController1 release];    
}else
{
    FirstViewDetail *detailViewController = [[FirstViewDetail alloc] initWithItem:boy];

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

}

I would try to use if (boy == nil) but that doesn’t seem to work either.

Instead do this:

NSString *str = [NSString stringWithFormat:@"%@", boy];
if ([str isEqualToString:@""]) {
    //boy is nil do your stuff
}
