[問題] NSUserDefault跨ViewController傳值
最近在練習撰寫購物清單時
我是先把值存入在viewController裡的NSuserdefault，
再到tableViewController顯示購買項目
之後重啟程式後點擊預覽清單，之前的值都還在
但只要再輸入新資料，那些就資料就會被覆蓋掉
以下的code是我在viewcontroller裡的viewDidLoad宣告的
self.itemArray = [[NSMutableArray alloc]init];
self.shoppingList = [NSUserDefaults standardUserDefaults];
