QuietLog, and a little demonstration

	#import <Foundation/Foundation.h>

	// clang -fobjc-arc -Wall -Wformat -Weverything -Wno-format-nonliteral -framework Foundation -o log log.m

	// Compiler likes explicit function prototypes prior to first use.
	// Add an attribute to get additional checking from the compiler
	extern void QuietLog (NSString *format, ...) __attribute__((format(__NSString__, 1, 2)));

	// !!! The attribute above isn't warning like it should, but NSLog's _is_ working.
	// This is NSLog's attribute. I'm currently baffled.

Set symbol breakpoint on objc_msgSend then setup this debug command to log all methods called in iOS Simulator. If you want to do device debugging change esp+4 register to r0, esp+8 to r1 Found long ago somewhere on stackoverflow.

expr -- (void)printf("[%s, %s]\n",(char *) object_getClassName(*(long*)($esp+4)), (char *) *(long *)($esp+8) )
