我一直收到错误“Int not convertible to CMAttachmentMode”。我不确定我应该如何转换这个变量才能让它在我的 CFDictionaryRef 中工作。如果有人可以解释，我将不胜感激。谢谢!
var attachmentMode = kCMAttachmentMode_ShouldPropagate as CMAttachmentMode
var attachments:CFDictionaryRef = CMCopyDictionaryOfAttachments(kCFAllocatorDefault, sampleBuffer, attachmentMode)
最佳答案
var attachmentMode = CMAttachmentMode(kCMAttachmentMode_ShouldPropagate)
var attachments:CFDictionaryRef = CMCopyDictionaryOfAttachments(kCFAllocatorDefault, sampleBuffer, attachmentMode)
关于ios - 将 Int 转换为 CMAttachmentMode，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29340476/
