NSCAssert() (ve ayrıca NSCAssert1() ... up dahil)

void assert(int expression); 

If expression evaluates to 0 (false), then the expression, source code filename, 
and line number are sent to the standard error, and then calls the abort 
function. 

If the identifier NDEBUG ("no debug") is defined with #define NDEBUG then the 
macro assert does nothing. 

Örnek:

assert(x != 0); 

not: 012 için assert.h

+0
