i'm new on this, i'm sorry anything. wish know why not being saved when close , open app again. thanks!!!!

answer posted! ideas! :d

add function:

func save() {         var appdel: appdelegate = (uiapplication.sharedapplication().delegate as! appdelegate)         var moc: nsmanagedobjectcontext = appdel.managedobjectcontext!         var whotook: anyobject! = nsentitydescription.insertnewobjectforentityforname("photolistentity", inmanagedobjectcontext: moc)         var error: nserror?         moc.save(nil)     }

and call in addbutton! done! :d
