Do you see this with v3.1.1 of the AdWhirl sdk?  Also, what is the particular 
error here?

• Changed state: Clarification

I updated to 3.1.1 and still seeing some random crashes at startup.  But I 
can't be sure yet the new crash has the same crash stack.  The code around this 
error still the same as 3.0.  By looking at this stack, my guess is that 
delegate is over released.

- (void)reportExImpression:(NSString *)nid netType:(AdWhirlAdNetworkType)type {
  NSURL *baseURL = nil;
  if ([delegate respondsToSelector:@selector(adWhirlImpMetricURL)]) {  // line 519
    baseURL = [delegate adWhirlImpMetricURL];
  }
  if (baseURL == nil) {
    baseURL = [NSURL URLWithString:kAdWhirlDefaultImpMetricURL];
  }
  [self metricPing:baseURL nid:nid netType:type];
}

Are you preemptively releasing the AdWhirlView or its delegate?  This bug 
report seems atypical, which makes me suspect an implementation issue on your 
side.

I am using a static adwhirl view.  i.e. all my viewcontrollers in my app shared 
a same static adwhirl view.  Is this ok?

I wonder if the following events will generate this error.  How to fix it?

1. view controller request new ad.  It sends request to the server but the 
response isn't back yet.
2. User pops the view controller thus causing delegate deallocate
3. Ad response comes back and the delegate is already deallocated.

Shall I set adView.delegate = nil in ViewWillDisappear to fix this problem?

I have a abstract view controllers which all my viewcontrollers inherits from.

AbstractUIViewController.m:

static AdWhirlView *adView =nil;
- (void) viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    // put the ad on the bottom

        if (adView == nil){
            adView = [[AdWhirlView requestAdWhirlViewWithDelegate:self] retain];  // retain to avoid dealloc problem due to memory pressure
            adView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin;
        }
        adView.delegate = self;
        [adView requestFreshAd];
        [self.view addSubview:adView];
        [self adjustAdSize];
 }
