楼主，你的项目很棒，向你请教一个问题，这里面的图片显示你是怎么处理的呢？比如遇到不规则的图片，那几种显示图片的方式并不能完全满足要求，如果进行裁剪，图片就会变模糊.你是怎么处理的呢？

您好！感谢您关注这个项目，不知道您说的是哪里的图片显示，如果是指图片模块中的每个cell中的搞笑图片，我是依据原图的宽高比来计算imageView的宽和高（宽是固定的，是屏幕的宽度，高是根据宽高比计算所得）
1.如果计算得到的高度在正常范围内（小于[UIScreen mainScreen].bounds.size.height-64-40)
那么会显示图片的全部，将imageView的contentMode设置为 UIViewContentModeScaleToFill;

2.如果计算得到的高度非常大（大于[UIScreen mainScreen].bounds.size.height-64-40)
如果计算的高度超出一定值，那么只会显示图片的中间部分，不需要裁剪和绘制，只需将imageView的contentMode设置为UIViewContentModeScaleAspectFill;
并且在imageView下方会有一个查看大图的按钮。

感谢您对TTNew的关注！谢谢！
