This is expected and documented behavior. From https://developer.apple.com/documentation/appkit/nscell/1532348-tag?language=objc
Setting the value of this property raises with NSInternalInconsistencyException <https://developer.apple.com/documentation/foundation/nsinternalinconsistencyexception?language=objc>. Subclasses are expected to override this property if they support tags If you want to use tags, you should subclass NSImageCell and implement -tag & -setTag: to return your own ivar. Hope that helps. —Rob > On Mar 16, 2019, at 7:03 PM, Carl Hoefs <newsli...@autonomy.caltech.edu> > wrote: > > macOS 10.12, ObjC > > Is it not possible to set the tag of an NSImageCell at runtime? > > At runtime when I do "myCell.tag = val;" I get a warning: > Stub implementation of -setTag by NSCell does nothing. > > I have an array of 48 NSImageCells.
