I want to push the view from left side instead of right side.
RequestAndLoadViewController *controller=[[RequestAndLoadViewController alloc]init];
[self.navigationController pushViewController:controller animated:YES];
[controller release];
here we pushing the RequestAndLoadViewController from right side
If you’re using a navigation controller, when you push a view it will always come from the right. If you want to make a view slide in from the left side you need to animate it manually.
