更改UIModalPresentationFormSheet模型样式的当前viewController的框架

Question

如何更改模型样式“UIModalPresentationFormSheet”的呈现viewController的框架

预期的框架

当前帧

我试过设置视图边界OverlayViewController.view.superview.bounds = CGRectMake（20,20,600,400）

设置了呈现视图的框架和中心

OverlayViewController.view.superview.autoresizingMask =
        UIViewAutoresizingFlexibleTopMargin |
        UIViewAutoresizingFlexibleBottomMargin |
        UIViewAutoresizingFlexibleLeftMargin |
        UIViewAutoresizingFlexibleRightMargin;
        CGRect screenBounds = [[UIScreen mainScreen] bounds];
        OverlayViewController.view.superview.frame = CGRectMake(20,20,600,400);
        CGPoint center = CGPointMake(CGRectGetMidX(screenBounds), CGRectGetMidY(screenBounds));

还试过setModalPresentationStyle:UIModalPresentationPageSheet，框架无法设置页面的原点

所以请建议如何做到这一点
