Does dismissViewControllerAnimated:completion: retain previous view controllers?

Question

I am having memory leaks and crashes in my app and I would like to know if they could be due to the way my container View Controller switches between View Controllers. The app should allow the user to navigate a long series of pages. Each page is laid out as a ViewController in the Storyboard (each page has a number as its identifier).
By the time I get to page 14 in the app, I can see in Instruments' Activity Monitor that the app takes about 600MB of memory (on an iPad 3). This is because each view controllers have UIImageViews with big images.
I am using ARC.
Below is the code for the container View Controller. Can you see a memory management problem somewhere?
@implementation PageNavigator
int startingPage = 0;
int currentPage = 0;
-(void)viewDidAppearBOOL)animated{
    NSLog(@"Starting book from page %d", startingPage);
    //do this only the first time the app runs
    if(startingPage != -1){
        UIViewController *currentPageVC = [self.storyboard instantiateViewControllerWithIdentifier:[NSString stringWithFormat:@"%d", startingPage]];
        [self presentModalViewController:currentPageVC animated:YES];
        currentPage = startingPage;
        startingPage = -1;
//currentPageVC and its outlets should get released when it gets out of scope, right?
-(IBAction)goToNextPage{
    [self dismissViewControllerAnimated:YES completion:^{
        currentPage++;
        UIViewController *currentPageVC = [self.storyboard instantiateViewControllerWithIdentifier:[NSString stringWithFormat:@"%d", currentPage ]];
        [self presentModalViewController:currentPageVC animated:YES];
        NSLog(@"Current Page is %d", currentPage);
Cheers

Hey Rahzah,
Couple tips to help diagnose and get your files to work.
Be sure to check that when you set a value like "Size" in a smaller breakpoint (region) that it highlights with the color that corresponds with that region color. The region color is the color of the bar above the ruler. This helps you notice which values carry across all regions, and which do not have values specific to a region.
If you want your setting for a value to pass on across all breakpoints (regions), hover on the input area and then click the button to the right to apply it across all regions.
Feel free to add a screen shot or ping with further details of your issue!
