大佬教程收集整理的这篇文章主要介绍了ios – [AVOutputContext(FigRoutingContext)currentRoutingContextFactory]中的崩溃AVFoundation，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我们在AVFoundation崩溃了.

Crashlytics写道：

但是我们不在app中使用其他线程.

Crashlytics日志：

初始代码：

self.volumeView = MPVolumeView.init(frame: CGRect.init(x: 0,y: 2,width: 52.0,height: 30.0))
self.volumeView?.showsVolumeSlider = false            self.volumeView?.showsRouteButton = true

self.volumeView?.setRouteButtonImage(UIImage.init(named: "streaming_icon"),for: .normal)
self.volumeView?.setRouteButtonImage(UIImage.init(named: "SELEcted_streaming_icon"),for: .SELEcted)

self.volumeView.sizeToFit()

请帮助解决此问题.
