there methods in cocoa classes accept address of pointer. commonly argument address of future nserror * object in coredata validation methods (among others). way possible put custom or owned object place of address given argument points to. my question is: why can't simple pointer arguments? e.g. let's have method: - (void)addobject:(id)someobject toarray:(nsmutablearray *)array; i can pass mutable array second argument, call addobject: on , after method call array modified. why not done nserror * objects? pointers passed methods defined const default? avoid accessing null ? why not done nserror * objects? because there's no such thing nsmutableerror . example works because can modify contents of array without modifying pointer array itself. however, since nserror instances immutable, cannot modify nserror . such, must create new error object. , if want return error object along other piece of data, @ least 1 of must done via out-parameter (...
