换行NSString stringWithFormat：跨越多行

Question

我正在将我的FMDatabase的SQL语句包装在NSString中。我想与行的回报保持干净像

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

有没有办法来包装一个长的SQL语句（实际的语句是更长的时间）在一个NSString换行？我宁愿不创建一个NSMutableString，然后appendFormat :.谢谢。

Answer 1

这应该工作：

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";
