Symbolizer 1.1
Briksoftware (via Karsten Kusche):
Symbolizer is the easiest way of converting vector graphics to bitmap graphics. Drag a vector graphic to Symbolizer and it'll show a detailed preview of the image. On the righthand side there's a list of preconfigured icon sizes ready for use in Xcode. Drag a size from there to the target folder and you're done. Symbolizer will automatically take care of naming the file.
