objective-c

 NSString* mimeType = (__bridge_transfer NSString*)UTTypeCopyPreferredTagWithClass
                                ((__bridge CFStringRef)assetInfo.dataUTI, kUTTagClassMIMEType);

assetInfo.dataUTI // UTI从PHAsset获取requestImage数据。

最佳答案

最后,我从UTI创建了mimeType

let mimeType = UTTypeCopyPreferredTagWithClass(dataUTI! as CFString, kUTTagClassMIMEType as CFString)?.takeRetainedValue() as String?
