Focus on the UISearchBar but the keyboard not appear

Question

I've read so many solution on how can i focus a searchbar to make keyboard appear when i open my search view, and all of that are like this

[searchBar becomeFirstResponder];
mine is 
[self.searchDisplayController.searchBar becomeFirstResponder];
but I tried both.

Now, I tried this, and I also added a

[self.searchDisplayController setActive:YES];

because I'm using a SearchDisplayController, but so far the best result i can have is to have the cursor on the searchbar, the uitableview with an overlay on it, but still no keyboard.

If I run the simulator I can type on the searchbar with my computer's keyboard, but on an iPhone I can't do anything.

If you want to give a look to my code: http://nopaste.info/39fcda4771.html the focus should be executed in viewDidLoad method

Thanks again.

Answer 1

I was showing searchbar on textFieldDidBeginEditing:(UITextField *)textField delegate method.

Keyboard was not showing. So for that first resign textField as firstResponder. i.e.

[textField resignFirstResponder];

Then call method with delay

[self performSelector:@selector(callSearchBar) withObject:NULL afterDelay:0.2];

Where

-(void)callSearchBar{
[self.searchDisplayController setActive: YES animated: YES]; 
self.searchDisplayController.searchBar.hidden = NO;
[self.searchDisplayController.searchBar becomeFirstResponder];

}

It works
