how know type of number stored on nsnumber object? in other words, there way check entry type of number when nsnumber created?

let's suppose store random number on nsnumber object:

nsnumber *intnumber = [nsnumber numberwithint:1]; 

of course want retrieve using intvalue method later:

int thevalue = [intnumber intvalue]; 

but if number came unknown source, api json response or whatever , parse nsdictionary, resulting on this:

{     "some key" : 1,     "some other key" : 74.1234 } 

we can assume some key has int value, while some other key has double.

is there way check type appropriated parse value on each key? use like:

for (nsnumber *number in _arrayofnumbers) {      if (/*number integer*/) {          //do integer stuff      } else if (/*number double*/) {          //do double stuff     } } 

i don't know if need use on real situation, wondering if there way check "entry type" of number.

thanks in advance.

use cfnumbergettype

cfnumbergettype((cfnumberref)number); 

you can throw value switch statement each value of enum cfnumbertype.
