I have tried to set the animation of a modalviewcontroller to false and the frame adjustments is not working, but when i try to turn the animation on it will work normally. Is there a fix for this?
below is the context of my code:

```
MyModal *modal = [[MyModal alloc] initWithNibName:@"MyModal" bundle:nil];
modal.modalPresentationStyle = UIModalPresentationFormSheet;

modal.view.superview.frame = CGRectMake(0, 0, 458, 230);
modal.view.superview.center = self.view.center;

[self.navigationController presentModalViewController:modal animated:NO];

```
