我得到 exc_bad_access 代码=2。有时它的工作没有错误，但有时它会出错。我不知道为什么会这样。如果有人发现任何问题，请告诉我这是我的代码..

 if (sqlite3_open(dbpath, &adhDB) == SQLITE_OK)
            {
                sqlite3_stmt *compiledStatement;

                const char *sqlStatement = "INSERT INTO tblNotifications (NotificationID,Description,BeforeHrs,AfterHrs,PreparationID,PreparationName,ProcedureID,ProcedureName,ClientID,IsActive,UpdatedDateTime) VALUES (?,?,?,?,?,?,?,?,?,?,?)"; // Total 11 ?
                NSLog(@"sqlStatement = %s",sqlStatement);


                if(sqlite3_prepare_v2(adhDB, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK)

试试这个：我认为不止一个 sql 语句在循环中触发，现在我们使用函数触发并且每次创建新的编译语句时......所以它不会崩溃。

        for (statusNotification in nsNotification)
        {
            NSString *NotificationID1 =[statusNotification objectForKey:@"NotificationID"];

            NotificationID1 =  [NotificationID1 stringByTrimmingCharactersInSet:
                        [NSCharacterSet whitespaceCharacterSet]];

            NSString *Description1 = [statusNotification objectForKey:@"Description"];
            Description1 =  [Description1 stringByTrimmingCharactersInSet:
                     [NSCharacterSet whitespaceCharacterSet]];


            NSString *BeforeHrs1 = [statusNotification objectForKey:@"BeforeHrs"];
            BeforeHrs1 =  [BeforeHrs1 stringByTrimmingCharactersInSet:
                   [NSCharacterSet whitespaceCharacterSet]];

            NSString *AfterHrs1 = [statusNotification objectForKey:@"AfterHrs"];
