16,642 PointsWhy doesn't Amit need to cast [segue destinationViewController] as an instance of the DetailViewController class?
I noticed that in my (newer version of) xCode, the Master/Detail template prepareForSegue function calls the topViewController property of [segue destinationViewController], then casts this as an instance of the DetailViewController class. However, in this video, Amit just calls the setDetailItem method directly on the [segue destinationViewController]. Is this due to a new feature in xCode, or am I missing something?
Here's my function, then his:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSString *object = self.titlesArray[indexPath.row];
DetailViewController *controller = (DetailViewController *)[[segue destinationViewController] topViewController];
[controller setDetailItem:object];
}
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSString *object = self.titlesArray[indexPath.row];
[segue destinationViewController setDetailItem:object];
}
}
