Objective-C NSString isEqualToString not getting match -

if have array created so:

nsarray* arritems = [[nsarray alloc] initwithobjects:@"one", @"two", @"three", nil]; 

and have class nsstring property:

myclass.myclassstring = @"one"; 

shouldn't isequaltostring work if this:

nsstring* strtocheck = myclass.myclassstring  for(int i=0; i<arritems.count; i++) {      nsstring* strthisitem = [arritems objectatindex:i];       if ([strthisitem isequaltostring:strtocheck]) {         nslog(@"okley dokley!");     }  } 

edit:

real world results:

in app not getting match - log out put both strings , length - @ safety marketing matching - there should "ok" logged here.

yes, should work. perhaps myclass.myclassstring not getting value want before isequaltostring check.

nslogs printing myclass.myclassstring, strtocheck , arritems should find goes wrong.

now saw edit:

safety_marketing_16 <- 2 underscores

safety marketing_16 <- 1 underscore

;)

(thank much! :d )
