小编use*_*093的帖子

我尝试使用以下代码将url转换为UIImage:

            let url = URL(string: "http://www.apple.com/euro/ios/ios8/a/generic/images/og.png")
            let sessionTask = URLSession.shared
            let request = URLRequest(url: url!)
            let task = sessionTask.dataTask(with: request, completionHandler: {(data: Data?, response: URLResponse?, error: Error?) -> Void in
                if (error == nil) {
                    let image: UIImage = UIImage(data: data!)!

                }

            })
            task.resume()

但它对我不起作用,if-loop没有被遵守.
