A simple way to reuse your Strings.xml file from your Xamarin.Android app in Xamarin.IOS. To use, this all you have to do is include the Strings.xml file in the root of your project as a Bundle Resource.

IOSResourceManager

public static class ResourceManager
	{
		static XDocument stringsDoc;

		static XDocument integersDoc;

		static ResourceManager ()
		{
			stringsDoc = XDocument.Load ("Strings.xml");
			integersDoc = XDocument.Load ("Integers.xml");
		}

		public static string GetString(string key)
		{
			IEnumerable<XElement> strings =
				(from el in stringsDoc.Root.Elements("string")
				 where (string) el.Attribute("name") == key
				 select el);

			return strings.First ().Value;
		}

		public static string[] GetStringArray(string key)
		{
			IEnumerable<XElement> strings =
				(from el in stringsDoc.Root.Elements("string-array")
				 where (string) el.Attribute("name") == key
				 select el);
			var values = strings.First ().Descendants ().Select (x => x.Value).ToArray ();
			for (int j = 0; j < values.Length; j++) {
				values [j] = values[j].Replace("\\'", "'");
			}
			return values;
		}

		public static int GetInteger(string key)
		{
			IEnumerable<XElement> integers =
				(from el in integersDoc.Root.Elements("integer")
				 where (string) el.Attribute("name") == key
				 select el);

			return int.Parse(integers.First ().Value);
		}
