如何在iOS中将数据转换为图像

let renderer = UIGraphicsImageRenderer(size: size)
let image = renderer.image { context in
    // 在这里绘制内容
}

let colorSpace = CGColorSpaceCreateDeviceRGB()
let context = CGContext(data: nil, width: Int(size.width), height: Int(size.height), bitsPerComponent: 8, bytesPerRow: 0, space: colorSpace, bitmapInfo: CGImageAlphaInfo.premultipliedLast.rawValue)!

// 在这里绘制内容

let cgImage = context.makeImage()!
let image = UIImage(cgImage: cgImage)

let data = Data() // 图像数据
let imageSource = CGImageSourceCreateWithData(data as CFData, nil)!
let image = UIImage(cgImage: CGImageSourceCreateImageAtIndex(imageSource, 0, nil)!)
