LTScrollExtension.swift中如下代码是什么意思

[bw-bianwei]

public class func initializeOnce() {
        DispatchQueue.once(token: UIDevice.current.identifierForVendor?.uuidString ?? "LTScrollView") {
            let didScroll = "X25vdGlmeURpZFNjcm9sbA==".glt_base64Decoding()
            let originSelector = Selector((didScroll))
            let swizzleSelector = #selector(glt_scrollViewDidScroll)
            glt_swizzleMethod(self, originSelector, swizzleSelector)
        }
    }

这段代码中“ let didScroll = "X25vdGlmeURpZFNjcm9sbA==".glt_base64Decoding()”是什么意思， "X25vdGlmeURpZFNjcm9sbA=="这一串是怎么得到的

base54解码就是"_notifyDidScroll"，UIKit里的私有方法，怕被拒就做了一下简单的加密
