Answer 1

Write viewWillAppear instad of viewDidAppear/viewDidLoad.

BecauseviewWillAppear method is call at the time of View will appear (in process), for more information about viewWillAppear read this official Document.

- (void)viewWillAppear:(BOOL)animated
{
    [self.searchBar becomeFirstResponder];
    [super viewWillAppear:animated];
}
