zorgiepoo / copyfromnetworkvolume.m
Last active October 9, 2015 05:30
Can't figure out how to copy a symbolic link, or a directory containing a symbolic link, that is originating on a different Network Volume (eg: in my case it's via AFP, or is it SMB2 these days..?)
// Note that on the command line cp -R /Volumes/mayur/bar.txt /Users/msp/Desktop/bar.txt
// works just fine; the symbolic link is copied, and it's not followed
// But I have *no idea* how to do this programatically as shown below
// (Note: My end goal is being able to copy an app from a volume to my local disk, but
// it fails when it encounters a symbolic link)
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSURL *sourceURL = [NSURL fileURLWithPath:@"/Volumes/mayur/bar.txt"]; // this is a symbolic link
NSURL *destinationURL = [NSURL fileURLWithPath:@"/Users/msp/Desktop/bar.txt"];
// this outputs 1, so the source does exist

Using https://developer.apple.com/reference/uikit/nstextstoragedelegate/1534375-textstorage?language=objc which is documented to allow changing attributes
// I'm not using the passed editRange and delta because I've found them to be quite misleading...
// This happens to be a new API (macOS 10.11) so maybe it's not really battle tested or I don't know what I'm doing
// Either way I'd like to support older systems so for portability sake it's easier to not use these parameters
- (void)textStorage:(NSTextStorage *)textStorage didProcessEditing:(NSTextStorageEditActions)editedMask range:(NSRange)editedRange changeInLength:(NSInteger)__unused delta

Unable to run UI Tests because Xcode Helper does not have permission to use Accessibility.
To enable UI testing, go to the Security & Privacy pane in System Preferences, select the Privacy tab,
then select Accessibility, and add Xcode Helper to the list of applications allowed to use Accessibility.
