我在 UICollectionViewCell 中有一个 UIButton。想从此单元格获取 json id。我完美地解析了 UICollectionViewController 中的 json 数据。单击 UICollectionViewCell 中的 UIButton 时,我一直在结束 ID 遇到的问题。
这是我的代码
JSON
{
"error": false,
"product_sellers": [
{
"id": 5,
"store_name": "ahmedstore",
"photo": "user_12-06-2017-12-32-56.png",
"is_favorite": 0
},
{
"id": 122,
"store_name": "aitldev6",
"photo": null,
"is_favorite": 0
},
{
"id": 123,
"store_name": "aitlmanager",
"photo": "user_2017-08-31-10-06-am (16).jpg",
"is_favorite": 0
},
{
"id": 135,
"store_name": "ajanta library",
"photo": "user_2017-08-19-7-16-am23931.png",
"is_favorite": 0
},
Collection View Controller
类 ProductStoreCollectionViewController:UICollectionViewController,UICollectionViewDelegateFlowLayout {
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "..........")
URLSession.shared.dataTask(with:url!) { (urlContent, response, error) in
if error != nil {
print(error ?? 0)
}
else {
do {
let items = json["product_sellers"] as? [[String: Any]] ?? []
self.arrStore = [Store]()
for item in items {
let oStore = Store()
oStore.id = item["id"] as? Int
oStore.image = item["photo"] as? String
oStore.store_name = item["store_name"] as? String
oStore.is_favorite = item["is_favorite"] as? Int
ProductStoreId.store_id = oStore.id!
self.arrStore.append(oStore)
}
} catch let error as NSError {
print(error)
}
DispatchQueue.main.async(execute: {
self.collectionView?.reloadData()
})
}
})
UICollectionViewCell
class StoreCollectionViewCell: BaseCell{
let heartBtn: UIButton = {
let btn = UIButton()
btn.setImage(UIImage(named: "heart_white_copy"), for: .normal)
btn.translatesAutoresizingMaskIntoConstraints = false
return btn
}()
var sellerId2: Int = 1
func heartBtnClick(){
print("box Btn click")
self.sellerId2 = ProductStoreId.store_id
print("add to favoriteStore\(self.sellerId2)")
}
override func setupCell() {
heartBtn.addTarget(self, action: #selector(heartBtnClick), for: .touchUpInside)
addSubview(heartBtn)
}
}
最佳答案
这是因为您的 ProductStoreId.store_id
在您解析它时存储了最后一个 ID。
你需要在你的数据源方法中分配id
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
// Your code
let store = self.arrStore[indexPath.row] // Please correct it if not
cell.sellerId2 = store.id
}
然后在您的 StoreCollectionViewCell
类中
func heartBtnClick(){
print("box Btn click")
//We don't need the below line
//self.sellerId2 = ProductStoreId.store_id
print("add to favoriteStore\(self.sellerId2)")
}
