在iPhone上自定义NSLog功能

我知道可以对Objective C中的选择器和方法进行方法混淆.是否可以将诸如NSLog之类的函数混淆到我们的自定义函数中.我想在自定义函数中与NSLog一起添加一些额外的功能.

I know that it's possible to do method swizzling for Selectors and Methods in Objective C. Is it possible to swizzle functions like NSLog to our custom function. I wanted to add some extra functionality along with NSLog in the custom function.

我最终使用了另一个函数，该函数将在内部调用NSLog.

I finally ended up using another function which will call NSLog internally.

#define NSLog(...) CustomLogger(__VA_ARGS__);

void CustomLogger(NSString *format, ...) {
    va_list argumentList;
    va_start(argumentList, format); 
    NSMutableString * message = [[NSMutableString alloc] initWithFormat:format 
                                                arguments:argumentList];


    [message appendString:@"Our Logger!"];
    NSLogv(message, argumentList);

    va_end(argumentList);
    [message release];
}
