更新SQLite數據庫只能使用一次

Question

我有一個SQLite數據庫和它裝入的tableview，現在，當我點擊一行來看看它的details..i去其中的細節顯示和AddToFav按鈕存在另一個視圖控制器。 當我點擊it..and去到另一個視圖控制器......我能看到的變化正確的，我的數據庫正確更新，但如果我嘗試添加其他entry..i通知我的數據庫沒有更新了.. addToFav按鈕只更新一次數據庫。有任何想法嗎？ 這是我的Addbut IBaction：

- (IBAction)AddButClick:(UIButton *)sender { 



    [AddBut setImage:[UIImage imageNamed:@"apple-logo copy.png"] forState:UIControlStateSelected]; 
    [AddBut setImage:[UIImage imageNamed:@"apple-logo copy.png"] forState:UIControlStateHighlighted];

     // NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"dictionary.sqlite"]; 
     //NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"authorsDb2.sqlite"]; 
     //  NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"FinalDb.sqlite"]; 
     //NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"xxJuridique-FINAL-OK.sqlite"]; 
    // [self createEditableCopyOfDatabaseIfNeeded]; 


    //  NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"data.sqlite"]; 
     // [self.tableView reloadData];
