The NSControl -tag property can be used to identify an action sender. Can the NSUserInterfaceItemIdentification protocol property -identifier be safely used for the same purpose?
It was introduced to support window restoration. The docs apply several caveats with regard to the identifier: https://developer.apple.com/library/mac/documentation/cocoa/reference/NSUserInterfaceItemIdentification_Protocol/Introduction/Introduction.html From the above: You should not change the value of a window’s identifier after adding any views to the window. For views and controls in a window, the value you specify for this string must be unique on a per-window basis. The slash (/), backslash (\), or colon (:) characters are reserved and must not be used in your custom identifiers. Similarly, Apple reserves all identifiers beginning with an underscore (_) character. Applications and frameworks should use a consistent prefix for their identifiers to avoid collisions with other frameworks. For a list of prefixes used by the system frameworks, see “OS X Frameworks” in Mac Technology Overview.
