I have a view controller this view controller has a UIView which was added in the builder. In viewdidload the UIView is hidden but when you click a button the UIView should appear but doesn't. I have linked the Outlets correctly and linked the UIView to the files owner but no luck. It was working until i modified something in the xib.

```
- (void)buttonRVClick:(id)sender{

[UIView animateWithDuration:0.3 animations:^{
    viewRV.alpha = 1;
}];
self.viewRV.hidden = NO;

[self.tableView2 reloadData];
}

```
