ios - 给定图像数据和 UTI 转换为 JPEG

Question

给定数据及其 UTI，将其转换为 JPEG 的正确方法是什么？

PHImageManager.default().requestImageData(for: asset, options: options, resultHandler: { (imageData: Data?, dataUTI: String?, _, _) in  
    guard let imageData = imageData, let dataUTI = dataUTI else { return }  
    if !UTTypeConformsTo(dataUTI as CFString, kUTTypeJPEG) {  
        //TODO: Convert to JPEG  

    }  
})

刚刚遇到 PHImageManager 将数据返回为 .heic 而不是 .jpeg 的问题，这对我有用:

PHImageManager.default().requestImageData(for: asset, options: PHImageRequestOptions(), resultHandler: { (data, string, orient, info) in
    if string?.range(of: ".heic") != nil || string?.range(of: ".heif") != nil {
        let rawImage = UIImage(data: data!)
        self.uploadData = UIImageJPEGRepresentation(rawImage!, 1.0)
        self.uploadName = "public.jpeg"
    } else {
        self.uploadData = data
        self.uploadName = string
    }
    self.uploadFileToServer()
})
