Methods

add(view, attrs = {})

Adds the view to the screen after applying the attributes. Attributes are converted to camel case if necessary. attrs is usually either a hash, method call that returns a hash, or the name of a method call (in the form of a :symbol) that returns the hash.

add UIInputView.new, {
  background_color: UIColor.grayColor,
  accessibility_label: "My input view",
  frame: CGRectMake(10, 10, 300, 40)
}

# or use a symbol which calls a method
def my_input_style
  {
    background_color: UIColor.grayColor,
    accessibility_label: "My input view",
    frame: [[10, 10], [300, 40]],
  }
end

add UIInputView.new, :my_input_style # will call my_input_style to get the hash

@input = UITextInput.new
