func uiImage2Base64(_ image: UIImage) -> String {
    // UIImage转Data
    let imageData: Data? = image.jpegData(compressionQuality: 1.0)
    // Data编码为Base64
    let str: String = imageData!.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    return str
}

PNG编码

func imageToBase64(_ image: UIImage) -> String {
    // UIImage转Data
    let imageData: Data? = UIImage.pngData(image)()
    // Data编码为Base64
    let str: String = imageData!.base64EncodedString()
    return str
}

func data2UIImage(_ image: Data) -> UIImage {
    // Base64解码为Data
    let imageData:Data? = Data(base64Encoded: image, options: .ignoreUnknownCharacters)
    // Data转UIImage
    let uiimage: UIImage = UIImage.init(data: imageData!)!
    return res uiimage
}

完成
