I think this should work:

@button = add UIButton.buttonWithType(UIButtonTypeRoundedRect), {
  # Other stuff here
}

# You have to set the title of a uicontrol with a method call instead of 
# an attribute because of the different states a uicontrol can be in.
@button.setTitle("My Title", forState: UIControlStateNormal)

good luck!

Sorry if this is a stupid question, but going along with this, can you
set the action for the button in the hash?

You have to set the title of a uicontrol with a method call instead of

an attribute because of the different states a uicontrol can be in.

@button.setTitle("My Title", forState: UIControlStateNormal)

good luck!

I don't believe so. You would probably be best creating the element and putting it on the screen and then using something like bubblewrap's on_tapped event handler with a block or function callback - https://github.com/rubymotion/BubbleWrap#ui

Actually, @markrickert, there's an undocumented feature of set_attributes that allows for doing that syntax:

@button = add UIButton.buttonWithType(UIButtonTypeRoundedRect), {
  "setTitle:forState:" => [ "My Title", UIControlStateNormal ],
  "addTarget:action:" => [ self, :my_custom_action ]
}

I want to DSL the addTarget:action: one into just action:. Shouldn't be too difficult.

@markrickert Your suggestion works for me. Thanks!

The following produced a fully working button with action that responds to button touch:

@button2 = add UIButton.buttonWithType(UIButtonTypeRoundedRect), {
      frame: CGRectMake(20, 80, 280, 40),
      "setTitle:forState:" => [ "Customers", UIControlStateNormal ],
      "addTarget:action:forControlEvents" => [ self, :view_customers, UIControlEventTouchUpInside ]
    }

Awesome, @beauohara .

How could I add a "parameter" to the method that this button calls?

So, if my action is :archive_customer and I need to send back the customer_id when this button is tapped, how would I do that?

I'd advise making things a bit easier with BubbleWrap

Like so:

@button2 = add UIButton.buttonWithType(UIButtonTypeRoundedRect), {
  frame: CGRectMake(20, 80, 280, 40),
  "setTitle:forState:" => [ "Customers", UIControlStateNormal ]
}

@button2.when(UIControlEventTouchUpInside) do
  archive_customer("some_customer_id")
end
