能固定整个menu高度吗？

menu高度能固定吗，像tableview一样，能上下滑动的？

添加了一个menuShowDefaultRows属性。

// FTConfiguration
public var menuShowDefaultRows:Int = 0

fileprivate func configurePopMenuFrame() {
       //...
        if (arrowDirection == .Up) {
             popMenuFrame = CGRect(x: popMenuOriginX, y: (senderRect.origin.y + senderRect.size.height), width: configuration.menuWidth, height: popMenuHeight)
            if configuration.menuShowDefaultRows > 0 {
                let height = configuration.menuRowHeight * CGFloat(configuration.menuShowDefaultRows) + FTDefaultMenuArrowHeight
                 popMenuFrame = CGRect(x: popMenuOriginX, y: (senderRect.origin.y + senderRect.size.height), width: configuration.menuWidth, height: height)
            } 
        }
    }

估计要改下源码就可以支持
