看了一下源码，弹幕文字的动画是通过注册CADisplayLink 指定update方法不停的改变的x和y坐标实现动画的，但是UITextField键盘事件的优先级比CADisplayLink事件高，runloop被添加进来了一个高优先级的任务，CADisplayLink下一次的调用就会被暂停转而先去执行高优先级的任务，然后在接着执行CADisplayLink的调用，从而造成动画过程的卡顿，使动画不流畅。作者能帮忙解决一下这个问题吗，建议动画能改成用CABasicAnimation的形式，估计能解决此问题。

BarrageRenderer 没有用 CAAnimation，现有思路下不可能改成 CAAnimation 实现方式。目前 CADisplayLink 使用的是 RunLoopCommonModes，这已经是一个高优先级了。卡顿很严重吗？

很严重倒是不会，就是弹起键盘的时候卡顿一下，强迫症感觉难受，不是很完美，我这边QA也给提了bug，寻思着你这边能否给予修复。你可以github上的demo下载下来加个输入框感受一下。

我也遇到了这样的问题，键盘弹起时，弹幕突然停顿了一下。
