換行NSString stringWithFormat：跨越多行

Question

我正在將我的FMDatabase的SQL語句包裝在NSString中。我想與行的回報保持乾淨像

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

有沒有辦法來包裝一個長的SQL語句（實際的語句是更長的時間）在一個NSString換行？我寧願不創建一個NSMutableString，然後appendFormat :.謝謝。

Answer 1

這應該工作：

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";
