打印变量名称目标C [英] Print out the variable name objective-C

问题描述

从上一个问题继续： Obj-C中的日志方法名称。我只是想知道是否有一种打印变量名的方法。例如：

Continued from the last question here: Log method name in Obj-C . I just wondered if there is a way to print out the variable name as well. For example:

NSString *name = "vodkhang";
NCLog(@"%@", name);

，我希望输出应该是：

name: vodkhang

只是总结上一篇文章目前，当我打电话给我时，我可以列出类名，方法名和行号。

Just to summarize the previous post, currently, I can print out the class name, method name and the line number when I call

NCLog(@"Hello World");
<ApplicationDelegate:applicationDidFinishLaunching:10>Hello world

with

#define NCLog(s, ...) NSLog(@"<%@:%d> %@", __FUNCTION__, __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__])

推荐答案

#define logIntVariable(x) NSLog( @"Value of %s = %d",#x, x)


- (void) myRoutine {
   int intValue = 5;

   logIntVariable(intValue);
}
