将image / jpeg从GET请求转换为UIImage

Question

我有一些限制，无法使用本机序列化程序或Alamofire。我只对身体（编码图像）和Content-Type = image / jpeg做出回应。这段代码不起作用：

let responseString = response as! String
let data = NSData(bytes: responseString, length: responseString.characters.count)
let image = UIImage(data: data, scale: 1.0) // nil

Answer 1

您的回复本身就是NSData直接尝试

var image = UIImage(data: response, scale: 1.0)
