I have an object that is an NSRuleEditorDelegate
for an NSRuleEditor
whose nestingMode
is NSRuleEditorNestingModeList
. There are 8 different possible criteria. Each criterion is optional but at least 1 is required (ruleEditor.canRemoveAllRows = NO
). Each criterion should only be added once. How can I limit adding a criterion for a row if it is already in the editor at a different row?
Thanks!
