strPath = [NSURL URLWithString:strPath].standardizedURL.absoluteString;

This line of code still cannot prevent directory backtracking, which should be "a/b/../c.txt" -> "a/b/c.txt"

Why should it be "a/b/c.txt"? The author of the archive can set any path they want under ".", and returning "a/c.txt" is fine and likely the desired behavior.
