在目标c中逃避%

Question

我想做一个sql语句 -

sqlStatement = [NSString stringWithFormat:@"SELECT * FROM movies where title like '%%@%'",searchKeyword];

但是sqlStatement正在成为 -

"选择*来自电影,其中标题为'%@'"

我想成功

"选择*来自电影,其中标题为'%searchKeyword%'"

如何逃脱"%"字符？

谢谢

Answer 1

试试:

sqlStatement = [NSString stringWithFormat:@"SELECT * FROM movies where title like '%%%@%%'",searchKeyword];

"%%"是打印'%'字符的方式.
