View not receiving touches after custom spinner is invoked - objective-c

Question

I followed the guide here to make my own custom view pop up to indicate I am searching for the users results:
http://joris.kluivers.nl/blog/2012/03/02/custom-popups-revisited/
When the search results are found, I dismiss the custom view, an a Flurry Ad pops up immediately. I click the x button on the ad and my next view appears. This view is not receiving any touch events anymore, neither is the tab bar at the bottom working. I suspect it has to do something with the custom view still animating away(via a transform to 0.0f) when the Flurry ad is coming up, but I am not sure. I am including the code for how the spinner is created, as well as the dismissal.
Note: I have confirmed the problem is related to Flurry Ads showing up modally while my customSpinner is going away. I don't know how to fix it though. When I don't display the Ad, the touch events are registering fine.
PCFFinder.c
- (void)queryServer:(NSString *)queryString {
__block PCFCustomSpinner *spinner = [[PCFCustomSpinner alloc] initWithFrame:CGRectMake(0, 0, 200, 200):#"Searching.."];
[spinner show];
NSString *url = #"https://selfservice.mypurdue.purdue.edu/prod/bwckschd.p_get_crse_unsec";
NSString *referer = #"https://selfservice.mypurdue.purdue.edu/prod/bwckgens.p_proc_term_date";
dispatch_queue_t task = dispatch_queue_create("Task 3", nil);
dispatch_async(task, ^{
NSString *webData = [PCFWebModel queryServer:url connectionType:#"POST" referer:referer arguements:queryString];
if (webData) {
classesOffered = [PCFWebModel parseData:webData type:2];
dispatch_async(dispatch_get_main_queue(), ^{
[spinner dismiss];
spinner = NULL;
if ([classesOffered count] > 0) {
if (self.view.window)
searching = NO;
//the ad pops up in the next view controllers viewWillAppear method and after exiting the ad, the views no longer work
[self performSegueWithIdentifier:#"ChooseClass" sender:self];
}else {
[spinner dismiss];
PCFCustomAlertView *alert = [[PCFCustomAlertView alloc] initAlertView:CGRectMake(0, 0, 300, 200) :#"Search Results" :#"No results were found. Please try broadening the search or double check your input." :#"OK"];
[alert show];
//the views still work here though..
searching = NO;
}
});
//rest omitted because it is irrelevant.
}
CustomPopup.c
-(void)dismiss
{
__block UIWindow *animatedWindow = self.window;
[UIView animateWithDuration:0.3f delay:0.0f options:UIViewAnimationCurveEaseOut animations:^{
animatedWindow.transform = CGAffineTransformMakeScale(0.0f, 0.0f);
}completion:^(BOOL finished) {
animatedWindow.hidden = YES;
animatedWindow = nil;
}];
}
-(void)show
{
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.windowLevel = UIWindowLevelAlert;
self.window.backgroundColor = [UIColor clearColor];
self.center = CGPointMake(CGRectGetMidX(self.window.bounds), CGRectGetMidY(self.window.bounds));
[self.window addSubview:self];
[self.window makeKeyAndVisible];
//animated
self.window.transform = CGAffineTransformMakeScale(1.5f, 1.5f);
self.window.alpha = 0.0f;
__block UIWindow *animationWindow = self.window;
[UIView animateWithDuration:0.3f delay:0 options:UIViewAnimationCurveEaseIn animations:^{
animationWindow.transform = CGAffineTransformMakeScale(1.0f, 1.0f);
animationWindow.alpha = 1.0f;
}completion:nil];
}
I have tried setting the view as first responder in the viewWillAppear method, but that doesn't work either.

In your dismiss method you are setting the single window to have a zero scale and hidden. This is surely your problem. Animate the pop ups view then remove it from the super view instead.
