Placing a view directly on top of another of the same size

Question

Ok, first what i'm trying to achieve:

A background video with interactive text over the top.

This text is being generated in the code i've written and is being presented in a UIView. The video is being played in an AVPlayerController, embedded in a UIContainerView.

My original plan was to set the UIView's width, height, and top to be equal to the UIContainerView's but this seems to be presenting me with a whole load of "Unable to simultaneously satisfy constraints" errors.

Am I going about this in the correct way? Has anyone tried to do something similar and succeeded?

Thanks, Joe

Answer 1

您可以尝试设置相等的宽度和相等的高度约束。如果这不能解决您的问题，您需要确定哪些约束确实存在冲突。
