包裹NSString stringWithFormat：跨多行

Question

我将我的FMDatabase的SQL语句包装在NSString中。我想用

之类的换行符保持清洁

SELECT * FROM table as t
JOIN location as loc 
on t.position = loc.value

有没有办法在带有换行符的NSString中包装一个长SQL语句（实际语句更长）？我宁愿不创建NSMutableString，然后appendFormat：。感谢。

Answer 1

这应该有效：

NSString *statement =
    @"line1\n"
     "line2\n"
     "line3\n";

Answer 2

NSString *query = @"SELECT * FROM table as t \
                    JOIN location as loc \
                    on t.position = loc.value";
