转换为JPEG给定的图像数据和UTI [英] Converting to JPEG given image data and UTI

问题描述

给出数据及其UTI，将其转换为JPEG的正确方法是什么?

Given Data and its UTI, what's the proper way to convert it to JPEG?

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  

    }  
}) 

推荐答案

PHImageManager只是将这个问题返回为.heic而不是.jpeg，所以对我有用:

Just had this issue with the PHImageManager returning the data as .heic instead .jpeg, this worked for me:

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()
})
