Question

这是我从服务器

收到的JSON

我的问题是在这里我收到两个＆＃34; imageData＆＃34;这是Array类型。如何提取每一个并将它们分配给集合视图单元格。正如在第一个imageData中，应该转到一个单元格，接下来就是这样。

我正在使用ALAMOFIRE和SWIFTYJSON。如果有人可以帮助我使用/不使用SwiftyJSON，我真的很感激。

我的JSON：

            print(json33)
            if let userDict = json33["response"].dictionary{

                if let array = userDict["docs"]?.array{

                    for imgd in array{

                        let me:String! = imgd["imageData"][0].string

                        let url = NSURL(string: me)!
                        let data = NSData(contentsOfURL: url)!
                        let image = UIImage(data: data)
                        let imgView = UIImageView(image: image!)
                        imgView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
                        self.view.addSubview(imgView)
                    }


                }

            }

每个词典都有一个图像文本条目，这些词典都在一个数组中。

我会使用flatMap快速获取这些图片字符串：

let allImageStrings = json["response"]["docs"].flatMap { $0.1["imageData"].first?.1 }

说明：我们迭代json["response"]["docs"]并访问元组的第二部分（记住，SwiftyJSON对象总是有(index, value)）并从那里我们取第一个元组的第二部分[ ＆＃34;为imageData＆＃34;。]

它看起来很复杂，但当你看到JSON结构时，它实际上相当清晰。

迭代数组并从JSON文件
