推荐答案

libRIP调用负责的此绘制带有背景图像的UIViewController.

According to this that libRIP call is responsible for drawing a UIViewController with a background image.

显然，当您使用[UIColor colorWithPatternImage:]设置视图的backgroundColor时，会发生此问题.

Apparently this problem happens when you're setting a view's backgroundColor using [UIColor colorWithPatternImage:].

一种解决方法是改为使用UIImageView作为背景.如此处所述.

A way around it is to use a UIImageView as background instead. As described here.
