I am developing an iPhone application and I use HTML to display formatted text.

I often display the same webpage, but with a different content. I would like to use a template HTML file, and then fill it with my diffent values.

I wonder if ObjectiveC has a template system similar to ERB in Ruby.

That would allow to do things like

Template:

<HTML>
  <HEAD>
  </HEAD>
  <BODY>
    <H1>{{{title}}}</H1>
    <P>{{{content}}}</P>
  </BODY>
</HTML>

ObjectiveC (or what it may be in an ideal world)

Template* template = [[Template alloc] initWithFile:@"my_template.tpl"];
[template fillMarker:@"title" withContent:@"My Title"];
[template fillMarker:@"content" withContent:@"My text here"];
[template process];
NSString* result = [template result];
[template release];

And the result string would contain:

<HTML>
  <HEAD>
  </HEAD>
  <BODY>
    <H1>My Title</H1>
    <P>My text here</P>
  </BODY>
</HTML>

The above example could be achieved with some text replacement, but that would be a pain to maintain. I would also need something like loops inside templates. For instance if I have multiple items to display, i would like to generate multiple divs.

Thanks for reading :)
