iphone - Can't seem to read UITextField value correctly -

-

i trying verify uitextfield, allows numbers isn't 0 (zero). check fails every time? when debugging resultingstring = '0'( type in 0 ) trying make fail, doesn't fail.

nsstring *resultingstring = budgetfield.text;

if(resultingstring == @"0" || [resultingstring length] == 0){     [apphelpers showalert:@"dude!" withmessage:@"don't cheap know have more $1"]; //never gets in here.     return; }

use "==" values, not strings:

 ([resultingstring intvalue] == 0 || [resultingstring length] == 0)
