导读：+(XYZAnswers *)myAnswerWithDate:(NSString *)date{ NSString *sqlString = [NSString stringWithFormat:@"SELECT * FROM MyAnswers WHERE dateString = '%@'",date]; sqlite3_stmt *statement = [[XYZSQLConnection shareSQLConnection] sqlPrepare:sqlStr

+(XYZAnswers *)myAnswerWithDate:(NSString *)date
{
    NSString *sqlString = [NSString stringWithFormat:@"SELECT * FROM MyAnswers WHERE  dateString = '%@'",date];
    
    sqlite3_stmt *statement = [[XYZSQLConnection shareSQLConnection] sqlPrepare:sqlString];
    XYZAnswers *tempAnswer = [[XYZAnswers alloc] init];

    while (sqlite3_step(statement) == SQLITE_ROW)

在进行

sqlite3_step(statement) 操作后记得sqlite3_finalize(statement); 释放资源

不然数据库出于自我保护，就会报这个错
