iphone - Getting property of an array with viewControllers -

i got array viewcontrollers different types, named viewcontrollersarray first check if type correct (questionviewcontroller) , want print out property.

for(nsuinteger = 0; i<viewcontrollersarray.count; i++) {  if ([[viewcontrollersarray objectatindex:i] iskindofclass:[questionviewcontroller class]])    {     nslog(@"%@",((questionviewcontroller*)[viewcontrollersarray objectatindex:i]).getqanswer );      } } 

however shows me (null) instead of nsstring property.

edit

what got far this:

for(nsuinteger = 0; i<viewcontrollersarray.count; i++) {      if ([[viewcontrollersarray objectatindex:i] iskindofclass:[questionviewcontroller class]]){         nslog(@"ident: %@", [[viewcontrollersarray objectatindex:i] ident]);         nslog(@"answer: %@", [[viewcontrollersarray objectatindex:i] getqanswer]);     } } 

the second nslog (getqanswer) works. getqanswer method in questionviewcontroller. first nslog (ident) shows incorrect output (null), property:

@property (strong, nonatomic) nsstring *ident; 

you typecasted questionviewcontroller

use

nslog(@"%@", [[viewcontrollersarray objectatindex:i] getqanswer]);  

edit:

as per comment viewcontrollersarray[0] gives sendviewcontroller.

you should change

iskindofclass: 

to

if( [[viewcontrollersarray objectatindex:i] class] == [questionviewcontroller class])
