Monotouch UIPopover iPhone覆盖_popoversDisabled

Question

我在youtube上看到了这个视频，在objective-c中他能够覆盖_popoversDisabled方法并允许它们显示在iPhone上。

我的问题是，我如何在单音中做同样的事情，如下所示：

This code was written by @hamzasood
===============================
=====popover code===========
=============================
@interface UIPopoverController (overrides)
+ (BOOL)_popoversDisabled;
@end

@implementation UIPopoverController (overrides)

+ (BOOL)_popoversDisabled { return NO;
}

@end
