NSLog Format Specifiers

These formatters are used with NSLog, and also Logging.h mentioned in a previous post. Take a look.

%d, %i	signed int
%u	unsigned int
%f	float or double
%e	float or double in standard form or scientific notation
%x	hex int
%X	hex int
%o	octal int
%c	character
%C	unichar
%@	object

Examples:

(1)
int num=9;
NSLog(@"The value of the integer is %i", num);
Result: The value of the integer is 9



(2)
NSDate *today= [NSDate date];
NSLog(@"the date is %@",today);
Result:  the date is 2012-11-17 01:15:00 +0000
