iPad custom size of modal view controller

Question

I have a couple of modal view controllers of certain size. I'm trying to avoid the use of custom views (creating full screen black translucent overlay over current view, add the modal view over that view, do the animations, etc) to present it because there is no modalPresentationStyle that fits the size of my controllers.

Now I'm using UIModalPresentationPageSheet but my view is smaller in height and I have an ugly blank space

Desired presentation

 _______________
|    _______    |
|   |       |   |
|   |  MyVC |   |
|   |       |   |
|    -------    |
 --------------- 

Actual presentation

 _______________
|   |       |   |
|   |  MyVC |   |
|   |       |   |
|   |-------|   |
|   | blank |   |
 ---------------    

If I use the UIModalPresentationFormSheet the container is smaller in width.

I'm trying to figure out how to do it but I don't know if it's possible. What is the solution to the problem of presenting a modal VC smaller than any of the presentationStyles? The only solution is to arrange a "custom modal view controller engine"? Popovers doesn't fit my design requirements :(

All these answers will not work on ios8 SDK.

This will work:

AboutViewController * _aboutViewController = [[AboutViewController alloc] init];
    _aboutViewController.modalPresentationStyle = UIModalPresentationFormSheet;
    if(IS_IOS8)
    {
        _aboutViewController.preferredContentSize = CGSizeMake(300, 300);
    }
    [self presentViewController:_aboutViewController animated:YES completion:nil];

In AboutViewController.m

- (void)viewWillLayoutSubviews{
    [super viewWillLayoutSubviews];

    if(!IS_IOS8)
    {
        self.view.superview.bounds = CGRectMake(0, 0, 300, 300);
    }
}

IS_IOS8

#define IS_IOS8 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)

In iOS 8 you can also use UIPresentationController which gives you more customization options.
