-[__NSCFArray bytes]: unrecognized selector sent to instance

I have saved the array of my products in the user default as below:

  NSUserDefaults *userDefault = [NSUserDefaults standardUserDefaults];
  [userDefault setObject:[NSKeyedArchiver archivedDataWithRootObject:plans] forKey:@"plans"];
  [[NSUserDefaults standardUserDefaults] synchronize];

and read the default as below:

    NSArray *plans;
    NSData *data = [[NSUserDefaults standardUserDefaults] objectForKey:@"plans"];
    if (data != nil)
    {
        plans = [NSKeyedUnarchiver unarchiveObjectWithData:data];
    }

But sometimes my app getting crashed with -[__NSCFArray bytes]: unrecognized selector sent to instance while calling unarchiveObjectWithData method.

At some point you must have stored an NSArray into NSUserDefaults instead of archived data. Have you tried clearing your user defaults and trying again?
