尝试让代码可读
我正在尝试创建一个像这样的定义
#define ICONS [NSArray arrayWithObjects: [NSNumber numberWithFloat:33.0f], [NSNumber numberWithFloat:93.0f], [NSNumber numberWithFloat:149.0f], [NSNumber numberWithFloat:205.0f], [NSNumber numberWithFloat:314.0f], [NSNumber numberWithFloat:370.0f], [NSNumber numberWithFloat:426.0f], [NSNumber numberWithFloat:482.0f], nil]
，但是，我想将其编写为行组织 - 以使代码可读，就像
#define ICONS [NSArray arrayWithObjects:
[NSNumber numberWithFloat:33.0f],
[NSNumber numberWithFloat:93.0f],
[NSNumber numberWithFloat:149.0f],
[NSNumber numberWithFloat:205.0f],
[NSNumber numberWithFloat:314.0f],
[NSNumber numberWithFloat:370.0f],
[NSNumber numberWithFloat:426.0f],
[NSNumber numberWithFloat:482.0f],
nil]
但是当我破坏行中的定义时，Xcode会疯狂地大喊大叫。
有没有办法打破界限并按照我想要的方式组织代码？
I am trying to create a define like this
#define ICONS [NSArray arrayWithObjects: [NSNumber numberWithFloat:33.0f], [NSNumber numberWithFloat:93.0f], [NSNumber numberWithFloat:149.0f], [NSNumber numberWithFloat:205.0f], [NSNumber numberWithFloat:314.0f], [NSNumber numberWithFloat:370.0f], [NSNumber numberWithFloat:426.0f], [NSNumber numberWithFloat:482.0f], nil]
but, I would like to write it organized in lines - to make the code readable, like
#define ICONS [NSArray arrayWithObjects:
[NSNumber numberWithFloat:33.0f],
[NSNumber numberWithFloat:93.0f],
[NSNumber numberWithFloat:149.0f],
[NSNumber numberWithFloat:205.0f],
[NSNumber numberWithFloat:314.0f],
[NSNumber numberWithFloat:370.0f],
[NSNumber numberWithFloat:426.0f],
[NSNumber numberWithFloat:482.0f],
nil]
but when I break the define in lines, Xcode yells like mad.
Is there a way to break the line and organize the code as I want?

要跨行分割 #define，您需要将
\附加到行中。To split a #define across lines you need to append
\to the lines.根据 C 规范，多行定义需要在每行末尾有一个 '\'：
Per the C spec, multiline defines need a '\' at the end of each line:
