tvOS: Focus not moving correctly

Question

I have a UIView with two buttons on it. In the MyView class I have this code:

-(BOOL) canBecomeFocused {
    return YES;
}

-(NSArray

        

Answer 1

You can override the preferredFocusEnviromnets with the following logic:

-(NSArray> *)preferredFocusEnvironments {
    if (condition) {
        return @[_editButton];
    }
    else {
        return @[_addButton];
    }
}

After setting it, you can call

[_myView setNeedsFocusUpdate];
[_myView updateFocusIfNeeded];

The condition could be BOOL condition = tableViewController.editing; or sg like that.

If that now works, you can call it with a delay (0.1 sec or so).
