iOS Terminating app due to uncaught exception ' this class is not key value coding-compliant for the key success.'

In my code I have to get the value from NSDictionary but it crashes and the crash issue is,

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFString 0x155000fa0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key success.'

Here I show the the code what I am trying.

NSLog(@"finalValNotify is: %@", finalValNotify);
if (finalValNotify) {
   int successResult=[[finalValNotify valueForKey:@"success"]intValue]; ====>This line app crashed
   if (successResult==1) {
      NSLog(@"finalValNotify is: %d", successResult);
   }
}

Here I show the printed NSDictionary value:

finalValNotify is: {"multicast_id":5704734283387573862,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1534486056437155%1dbdaa031dbdaa03"}]}

But I don't know the reason for why the crash was occur.

If finalValNotify is your NSDictionary then use as - 

int successResult = [finalValNotify[@"success"] intValue];
