Make back button go to the previous view programmatically

Question

I have a UIBarButtonItem and would like to programmatically set the action that goes to the previous controller (in my case, my previous view is a UITableViewController).

You could write this in your viewDidLoad method:

UIBarButtonItem *btn=[[UIBarButtonItem alloc] initWithTitle:@"Back"     style:UIBarButtonItemStyleBordered target:self action:@selector(btnClick)];
self.navigationItem.leftBarButtonItem=btn;

and then use this:

// call of method
-(void)btnClick
{
    [self.navigationController popViewControllerAnimated:YES];
}
