## Discussion

Discussion The following is an example implementation of this method. It changes the item scope, and returns the window the source image view is contained within. - (NSWindow *)sharingService:(NSSharingService *)sharingService               sourceWindowForShareItems:(NSArray *)items               sharingContentScope:(NSSharingContentScope *)sharingContentScope {     *sharingContentScope = NSSharingContentScopeItem;     return [_imageView window]; }
