RubyMotion

Showing a Message with UIAlertView

Now that we understand how our app boots up and we have our entry point, let’s try something. We’re going to show a UIAlertView, which is the standard blue pop-up you see when you get an error message or push notifications pre-iOS5. Let’s change application:didFinishLaunchingWithOptions: to add an alert right before returning.

first_app/HelloMotion_alert/app/app_delegate.rb

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @alert =
      UIAlertView.alloc.initWithTitle("Hello",
        message: "Hello, RubyMotion",
        delegate: nil,
        cancelButtonTitle: "OK",
        otherButtonTitles: nil)
    @alert.show

    puts "Hello from the console!"

    true
  end
