People like the new by-week/alert format of the Dispatch

After I sent out the first alert last week, some people contacted me and they liked the idea. So I’ll go ahead and use the new system.

If you missed the last issue, you can find it here: issue #47.

Happy coding, Todd Werth (@twerth)

RubyMotion Tip


UIAppearance protocol

The SDK has a concept called the UIAppearance protocol. It’s basically a global place to set various styles.

There are some problems with it:

  • You can only set some attributes on some views and controllers
  • The styles only get applied when a view is created, so you can’t use it for theming, where you need to change the theme while screens are already loaded

You still should use it, because if you can set something’s appearance it saves you from styling it throughout the app.

I usually create an StandardAppearance class like so:

class StandardAppearance
  def self.apply(window)
    Dispatch.once do

      UIWindow.appearance.tap do |o|
        o.tintColor = UIColor.redColor
        # set other attributes here
      end

    end
  end
end

Then I call it in AppDelegate:

StandardAppearance.apply @window

Or if I’m using RMQ (which of course I am), I call it in ApplicationStylesheet so that I can use my named colors, named fonts, etc:

class ApplicationStylesheet < RubyMotionQuery::Stylesheet

  def application_setup
    color.add_named :apricot, '#EEAA22'

    StandardAppearance.apply rmq.app.window
  end

end

The following have attributes you can set with appearance:

  • UIActivityIndicatorView
  • UIBarButtonItem
  • UIBarItem
  • UINavigationBar
  • UIPopoverController
  • UIProgressView
  • UISearchBar
  • UISegmentedControl
  • UISlider
  • UISwitch
  • UITabBar
  • UITabBarItem
  • UIToolbar
  • UIView
  • UIViewController
  • UIWindow

Thinking out loud


I personally have 4 rules for company culture: hire creative people, hire nice people, be honest with them as much as humanly possible, and then let them create the culture. Nothing else is needed.

I liked her talk on company cultures: Rocky Mountain Ruby 2014 – Your Company is “Awesome” (But is “Company Culture” a lie?)
