Question

I’m bringing focus to a UITextView after setting its .hidden property to NO. When I set the [textView becomeFirstResponder] the textView gets the little typing cursor, but the keyboard remains hidden. Any idea why? If it helps, the main view is a modal view that a UINavigationController is presenting.

EDIT: Here’s the method that gets called:

- (void)show_comment_elements {

    toolbar.hidden = YES;
    main_table.hidden = YES;
    add_comment_table.hidden = NO;
    comment_text.hidden = NO;

    [comment_text becomeFirstResponder];

}

Here’s a screenshot:

I’m assuming you’ve verified that your method is getting invoked after the view is placed on-screen.

From the docs….

A responder object only becomes the
first responder if the current
responder can resign first-responder
status (canResignFirstResponder) and
the new responder can become first
responder.

You may call this method to make a
responder object such as a view the
first responder. However, you should
only call it on that view if it is
part of a view hierarchy. If the
view’s window property holds a
UIWindow object, it has been installed
in a view hierarchy; if it returns
nil, the view is detached from any
hierarchy.

So:

1. Can you confirm that the current responder when your method is invoked can resign first-responder status?

2. Your view appears to be in the view hierarchy if it is displaying from the screen shot. If the screen-shot is from IB, then test that the view’s window property is not nil.

3. Make sure the view is editable — if(comment_text.isEditable) or it will not accept first responder status.

4. Try adding [comment_text setNeedsDisplay] to force a re-fresh with the view set as first responder.

If none of this works, post some more code (such as where the method is being called from).
