Appending CGPath to CGPath

I have a CGPath which represents a small (but somewhat complicated) shape and I want to append a number of them together, connected with straight lines, to form a complete closed shape which I then want to use as a clip region. I thought that CGPathAddPath would do what I wanted as I can easily

RFC 5322's address grammar is too complicated to allow for validation with a regular expression, and you're going to end up rejecting perfectly legitimate email addresses if you try. Plus, even if you somehow came up with the perfect validation routine, it doesn't ensure that the address is actu

Hi all, Of late, I've been working to remove NSString-based paths, FSRefs, and Alias Manager usage in my code, in favour of NSURL. But I'm having trouble with alias files. NSOpenPanel helpfully, by default, resolves aliases before it returns the URL to you. But NSPathControl does not and file d

Scott, are you copying the files asynchronously? I wonder if there are some files still in the process of being copied to the old directory, so the old directory either doesn't really go away, or it gets recreated. What happens if you comment out the actual copying of the files? And if you log t
