[MacRuby-devel] NSUserDefaults and registerDefaults

[Steve Clarke]

Hi Erik,

The following code works for me, though as far as I can see it's effectively the same as yours.  The only difference might be that I run this code in rb_main.rb  rather than after the app has finished launching.

DBNAME_KEY='database_name'
DEFAULTS = NSUserDefaults.standardUserDefaults
appDefaults = { DBNAME_KEY=>'bamford'}
DEFAULTS.registerDefaults(appDefaults)
puts DEFAULTS.stringForKey(DBNAME_KEY) => "bamford" if the key is not present in the plist.
