我有一个快速的项目，我使用Alamofire和swiftyJson来进行API调用，并返回一堆JSON值。我有一个类别和一个产品Model类，它们被传递给TableViewController，一切都很好。我将选定的类别ID和SLUG存储在变量中。我现在面临的问题是如何将与所选类别相关联的产品传递给productsTableViewController。所选类别JSON看起来像这样
[
{
"url": "http://127.0.0.1:8000/api/products/13/",
"id": 13,
"title": "ada",
"description": "how all this",
"structure": "standalone",
"date_created": "2018-05-13T17:41:59.935158Z",
"date_updated": "2018-05-26T17:25:19.024144Z",
"recommended_products": [],
"attributes": [
{
"name": "Gender",
"value": "Male"
}
],
"categories": [
"Clothes"
],
"images": [
{
"id": 11,
"original": "http://127.0.0.1:8000/media/images/products/2018/05/f4.jpg",
"caption": "",
"display_order": 3,
"date_created": "2018-05-26T17:25:19.155159Z",
"product": 13
}
],
},
我选择的类别为
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let category = CategoryServices.instance.categories[indexPath.row]
CategoryServices.instance.selectedCategory = category
print(category)
let index = IndexPath(row: indexPath.row, section: 0)
tableView.reloadRows(at: [index], with: .none)
tableView.selectRow(at: index, animated: false, scrollPosition: .none)
NotificationCenter.default.post(name: NOTIFY_CATEGORY_SELECTED, object: nil)
//pull revel back on selected
self.revealViewController().revealToggle(animated: true)
}
我有我的默认产品显示，即所有产品
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = tableView.dequeueReusableCell(withIdentifier: PRODUCT_CELL, for: indexPath) as? ProductsCell {
let product = ProductServices.instance.products[indexPath.row]
cell.configureCell(product: product)
return cell
} else {
return UITableViewCell()
}
}
产品细胞
func configureCell(product: Products) -> Void {
productPriceLabel.text = product.productPrice
producNameBtn.setTitle(product.productTitle, for: .normal)
if (product.productImg.count > 0 ) {
productImg.sd_setImage(with: URL(string: product.productImg[0]) )
} else {
productImg.image = UIImage(named: "image_not_found")
}
