Transition between UIAlertControllers

What I need to do is present an alert controller with a progressBar. Once the download is complete, I need to transition to a secondary alert controller with a Success! message and an "Ok" button for the user to just exit this setup. I have built the alerts separately and they are working well on their own (well the progress bar is kinda working...) but with this code:

I expect that when the progressBar hits 100% the first alert controller will be dismissed and the next alert will show up, but nothing is happenning This is my code:

-(void)settingUpToolsProgressPopUp {
 UIAlertController* progressAlert = [UIAlertController alertControllerWithTitle:@"Setting up tools ..." message:@"This could take a few minutes. Make sure to keep your tools near your mobile device." preferredStyle:UIAlertControllerStyleAlert];
 [self presentViewController:progressAlert animated:YES completion:^{
 //Progress bar setup
 UIProgressView *progressView;
 progressView = [[UIProgressView alloc]initWithFrame:CGRectMake(8.0, 98.0, progressAlert.view.frame.size.width - 16, 100.0)];

 [[progressView layer]setCornerRadius:50];
 progressView.trackTintColor = [UIColor whiteColor];
 progressView.progressTintColor = [UIColor blueColor];
      progressNumerator = 1.0;
      progressDenominator = 1.0;
      currentProgress = (float)(progressNumerator/progressDenominator);
      [progressView setProgress: currentProgress animated:YES];
 [progressAlert.view addSubview:progressView];

  if(currentProgress > 1.0){
      [self settingUpToolsProgressPopUp];
 } else if(currentProgress == 1.0){
      [self dismissViewControllerAnimated:YES completion:nil];
      [self successAlertPopUp];
 }

 }];


 }

p.s. I know that the values are hardcoded right now... but regardless of any values I use the transition doesn't happen. I don't have access to the updating values yet, so I can't use other values right now... but I would expect that if I am using 100% value, then the transition would happen anyway?

Can anyone point me int he right direction? Why isn't this code working for transitioning between these controllers?

Thanks so much!

You need to call successAlertPopUp method inside dismissViewControllerAnimated's completion handler: 

[self dismissViewControllerAnimated:YES completion:^{
    [self successAlertPopUp];
}];
