我一直在尝试从服务器 URL 获取产品的详细信息和图像。我能够获取详细信息但不能获取图像,因为图像是一个 JSONarray。请帮我检索查看代码的图像。顺便说一句,我使用了“Alamofire”库。非常感谢!
下面的 JSON:
{
"products": [
{
"product_id": 2,
"name": "Ring",
"description": "<p> </p>",
"price": 674,
"master_variant_id": 2,
"cost_currency": "USD",
"shipping_and_returns": "",
"city_or_state": null,
"state_or_province": null,
"user": {
"company_name": "Gift Shop",
"firstname": "giftvendor"
},
"master_variant_images": [
"https://s3.amazonaws.com/webdevapp/app/public/spree/products/2/product/ri1.jpg?1476104874"
],
"variants": [],
"product_url": "http://staging.giftintime.com/mobile/products/2"
}
}
下面是我的代码
var gifther = [Gifther]()
override func viewDidLoad() {
super.viewDidLoad()
tableview.delegate = self
tableview.dataSource = self
Alamofire.request("http://staging.giftintime.com/mobile/categories/2/subcategories").responseJSON { (response) in
let result = response.result
if let dict = result.value as? Dictionary <String, Any> {
if let giftherdata = dict["products"] as? [Dictionary<String, Any>] {
for obj in giftherdata {
let giftintime = Gifther(giftherData: obj)
self.gifther.append(giftintime)
//print(giftintime)
}
self.tableview.reloadData()
}
}
}
}
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = self.tableview.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! giftherTableViewCell
let Gift: Gifther
Gift = gifther[indexPath.row]
//Displaying values
cell.productnameLbl.text = Gift.productname
cell.companynameLbl.text = "By " + Gift.companyname
cell.priceLbl.text = Gift.price
cell.currencytypeLbl.text = Gift.currencytype
//cell.imageview?.image = UIImage(named: Gift.imagesUrl)
// cell.selectionStyle = UITableViewCellSelectionStyle.none
//Displaying image
Alamofire.request(Gift.imagesUrl ).responseImage { (response) in
debugPrint(response)
if let image = response.result.value {
cell.imageview.image = image
}
}
/*
Alamofire.request(Gift.imagesUrl as! URLRequestConvertible).responseData { (response) in
if response.error == nil {
print(response.result)
}
if let data = response.data {
cell.imageview.image = UIImage(data: data)
}
}
*/
return cell
}
下面是我在另一个类(class)的代码
class Gifther {
var _productname:String?
var _price:String?
var _currencytype:String?
var _companyname:String?
var _imagesUrl:String?
var _productUrl:String?
//product details
var _descriptionData: String?
var _shippingAndreturns :String?
var productname:String {
if _productname == nil {
_productname = ""
}
return _productname!
}
var price:String {
if _price == nil {
_price = " "
}
return _price!
}
var currencytype:String {
if _currencytype == nil {
_currencytype = ""
}
return _currencytype!
}
var companyname:String {
if _companyname == nil {
_companyname = ""
}
return _companyname!
}
var imagesUrl:String {
if _imagesUrl == nil {
_imagesUrl = ""
}
return _imagesUrl!
}
//商品详情
var productUrl:String {
if _productUrl == nil {
_productUrl = ""
}
return _productUrl!
}
var descriptionData:String {
if _descriptionData == nil {
_descriptionData = ""
}
return _descriptionData!
}
var shippingAndreturns:String {
if _shippingAndreturns == nil {
_shippingAndreturns = ""
}
return _shippingAndreturns!
}
init(giftherData: Dictionary<String , Any>) {
if let name = giftherData["name"] as? String {
self._productname = name
}
if let Price = giftherData["price"] as? Float {
self._price = String(describing: Price)
}
if let moneyType = giftherData["cost_currency"] as? String {
self._currencytype = moneyType
}
if let companyname = giftherData["user"] as? Dictionary<String, Any> {
if let name = companyname["company_name"] as? String {
self._companyname = name
}
}
if let image = giftherData["master_variant_images"] as? NSArray {
print("images are : \(image.count)")
self._imagesUrl = String(describing: image)
}
//Product details
if let Producturl = giftherData["product_url"] as? String {
self._productUrl = Producturl
}
if let description = giftherData["description"] as? String {
self._productUrl = description
}
if let shippingAndreturns = giftherData["shipping_and_returns"] as? String {
self._shippingAndreturns = shippingAndreturns
}
}
}
最佳答案
试试这个。
Alamofire.request(URL.init(string: "https://s3.amazonaws.com/webdevapp/app/public/spree/products/2/product/ri1.jpg?1476104874")! ).responseData { (response) in
//debugPrint(response)
if let image = response.result.value {
let img = UIImage.init(data: image)
cell.imageView?.image = img
}
}
替换这个 alamofire 方法希望这有帮助
