MemWatcher

Helps you keep an eye on your RubyMotion iOS app's memory and CPU usage.

Adds a little UILabel in the top left of the screen that shows CPU % and memory usage in MB.

Setup/Usage

gem 'mem-watcher'

class AppDelegate
  def application(app, didFinishLaunchingWithOptions: options)
    # ...
    MemWatcher.watch
    true
  end
end

Options

The env: option controls what environments MemWatcher will watch in. It defaults to "development" and can be a string or array of acceptable RubyMotion environments.

MemWatcher.watch(env: [ "development", "test" ])

If you want to attach the view to another view, provide it:

MemWatcher.watch(parent_view: @my_other_view)

Caveats

  • It only reports on the current app main process.
  • I have no idea how accurate it is. It does accurately show memory leaks, from what I can see.
