sqlite中默认字符串用单引号刮起来， 而不是双引号

strSql = [ NSString stringWithCString:"create table PFUserBlackList /

  ( address text primary key  not null unique /

  , data integer default(0) /

  , origin text default(" ") /

  , inter_switch integer default(1))"

];

 

 

strSql = [ NSString stringWithCString:"create table PFUserBlackList /

  ( address text primary key  not null unique /

  , data integer default(0) /

  , origin text default(' ') /

  , inter_switch integer default(1))"

];
