MWPhotoBrowser图片无法左右滚动切换的问题

使用MWPhotoBrowser浏览大图时有时会出现无法左右滑动切换图片，在github上找到了解决方法(https://github.com/mwaterfall/MWPhotoBrowser/issues/389),在 MWZoomingScrollView.m中的函数 layoutSubviews中添加下面的代码：

self.contentSize = CGSizeMake(floorf(self.contentSize.width), floorf(self.contentSize.height));原文：

in my case, a specific image (width 600 height 1600) can't scroll to others after vertical drag, but after zoom, it can scroll to others, I think it might be due to the fractional part of contentSize or zoom related, tail add the following code to the function
layoutSubviews in MWZoomingScrollView.m, it works for me.

self.contentSize = CGSizeMake(floorf(self.contentSize.width), floorf(self.contentSize.height));
