Simpler NSLog macro

Question

using iphone sdk 4.0 I want to remove the function name stuff from this macro but am struggling

#define LOG(fmt, ...) NSLog((@"%s " fmt), __PRETTY_FUNCTION__,##__VA_ARGS__)

i tried

#define LOG(fmt, ...) NSLog((@"%s " fmt), ##__VA_ARGS__)

but this results in a crash!!

I want to be able to log like this

LOG("text to log");
LOG("text to log with param %d", param); etc

Use these [here](http://stackoverflow.com/questions/969130/nslog-tips-and-tricks/969291#969291) — progrmr, Jul 13 '10 at 13:24

Why not simply like this ?

#define LOG(fmt, ...) NSLog(fmt, ##__VA_ARGS__)

I think you want this

#define Log(fmt, ...) NSLog(fmt, ##__VA_ARGS__);

You should wrap your log macro in a do{ }while(0); statement to avoid possibility of errors with if statements
