我有一个来自服务器的响应作为json对象,其中一个键将UIImage存储为Data。我怎么能得到这把钥匙的价值?
我现在拥有的:
let json = JSON(data: response.data!)
if json.count > 0 {
for (index , subJson):(String, JSON) in json {
if let photoThumbString = subJson["photoThumb"].string {
if photoThumbString.characters.count > 0 {
let data = photoThumbString.data(using: .utf8)!
feedObject.pictureData = data
}
}
}
但是如果我将Data对象转换回UIImage,那么图像将为nil:
if let pictureData = currentFeedObject.pictureData {
let image: UIImage? = UIImage(data: pictureData)
}
这是我收到的json(照片拇指值非常长,我只放了一小部分)
