问题描述
当我使用
NSLog(@fooBar)
pre>
它输出了很多我不想要的东西:
2009-09-03 13:46:34.531 MyApp [3703:20b] fooBar
有一种方法打印的东西到控制台没有这个大前缀?
我想在控制台中绘制一个表和其他一些东西,这样空间是至关重要的...解决方案这是来自borkware.com的Mark Dalrymple。

// NSLog()写出太多的东西。大多数时候我是
//对程序名称,进程ID和当前时间不感兴趣
//下降到子级别。
//这需要一个带有printf风格格式的NSString,并输出它。
//不能使用正常的旧printf,因为它不是
//支持'%@'格式选项。
void QuietLog(NSString * format,...)
{
va_list argList;
va_start(argList,format);
NSString * message = [[[NSString alloc] initWithFormat:format
arguments:argList] autorelease];
printf(%s,[message UTF8String]);
va_end(argList);
} // QuietLog
When I use
NSLog(@"fooBar")
it prints out a lot of stuff I don't want:
2009-09-03 13:46:34.531 MyApp[3703:20b] fooBar
Is there a way to print something to the console without this big prefix? I want to draw a table and some other things in the console so that space is crucial...

// NSLog() writes out entirely too much stuff. Most of the time I'm // not interested in the program name, process ID, and current time // down to the subsecond level. // This takes an NSString with printf-style format, and outputs it. // regular old printf can't be used instead because it doesn't // support the '%@' format option. void QuietLog (NSString *format, ...) { va_list argList; va_start (argList, format); NSString *message = [[[NSString alloc] initWithFormat: format arguments: argList] autorelease]; printf ("%s", [message UTF8String]); va_end (argList); } // QuietLog
