업데이트 Sqlite 데이터베이스는 한 번만 작동합니다.

Question

sqlite 데이터베이스가 있고 tableview에로드되었습니다. 이제 행을 클릭하여 세부 정보를 볼 수 있습니다 .i 세부 정보가 표시되고 AddToFav 버튼이있는 다른보기 컨트롤러로 이동합니다. 내가 그것을 클릭하고 다른보기 컨트롤러로 이동하면 ... 변경 사항을 올바르게 볼 수 있지만 데이터베이스가 올바르게 업데이트되고 있지만 다른 항목을 추가하려고하면 데이터베이스가 더 이상 업데이트되지 않습니다. addToFav 버튼은 데이터베이스를 한 번만 업데이트합니다. 어떤 아이디어? 이 내 Addbut IBAction를 수 있습니다 :

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



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

    @try { 
     // NSFileManager *fileMgr = [NSFileManager defaultManager]; 
     // 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];
