ios - [__NSCFNumber length]: unrecognized selector sent to instance with NSUserDefaults -


i creating 1 app in saving array of custom object in nsuserdefaults using below code :

[util setsubproductsarraypreference:myarray forkey:productid];

//util.m 

+(void)setsubproductsarraypreference:(nsmutablearray *)subproducts forkey:(nsstring *)string {     (int i=0; i<subproducts.count; i++) {         subproducts *po=[subproducts objectatindex:i];         nsstring *st=[nsstring stringwithformat:@"%d",i];         [util setsubproductspreference:po forkey:st];      }     nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];     nsdata *myencodedobject = [nskeyedarchiver archiveddatawithrootobject:subproducts];     [prefs setobject:myencodedobject forkey:string];     [prefs synchronize]; }   +(void)setsubproductspreference:(subproducts *)subproducts forkey:(nsstring *)key {     nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];     nsdata *myencodedobject = [nskeyedarchiver archiveddatawithrootobject:subproducts];      [prefs setobject:myencodedobject forkey:key];//here crashing     [prefs synchronize]; }

this code working fine ios7 , prior..the problem when running same code ios8 in xcode6 getting below error :

 [util setsubproductsarraypreference:myarray forkey:[nsstring stringwithformat:@"%@",productid]];

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
