macOS NSFileManager: Notification of moved files

[MacDonaldsd]

Hi all,

Im having a problem whereby I need to keep track of a few files on the system that my application keeps a URL reference to. The problem I am having is that I can't get any notification when these files are moved.

I tried the code below but it isn't working, the delegate methods never get called.

- (void)awakeFromNib
{
		
	NSFm=[NSFileManager defaultManager];
	
	[NSFm setDelegate:self];
	
	NSLog(@"Delegate %@", [NSFm delegate]);

	
}


- (void)fileManager:(NSFileManager *)manager willProcessPath:(NSString *)path{
	NSLog(@"File manager%@",manager);
	
}

- (BOOL)fileManager:(NSFileManager *)fileManagershouldMoveItemAtPath:(NSString *)srcPathtoPath:(NSString *)dstPath {
	
	NSLog(@"File manager");
	return YES;
}

If you want to track files when they are moved, you can use aliases (from Carbon). One Cocoa wrapper is NDAlias.

Yeah, NDAlias or similar is the way to go. As for why your code didn't work, you're fundamentally misunderstanding what NSFileManager does. It's isolated to just your application; so those delegate methods will only be called when you ask your NSFileManager instance to do something.

Also you mis-capitalized one of them.

Ok thanks,

I thought that was the problem.

Its more of a case that if they are moved I want to delete there related in my application.
