屏幕不显示数据，直到我点击屏幕或让它等待很长时间 这是我的代码
enter code here
BookMarkVC 类:
UIViewController,UITableViewDataSource,UITableViewDelegate {
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var menuButton: UIBarButtonItem!
var bookmarks = [DatumForBookMarksMoel]()
override func viewWillAppear(_ animated: Bool) {
getAllBookMarks { (succsees) in
if succsees
{
print ("get all book marks ")
self.tableView.reloadData()
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
menuButton.target = self.revealViewController()
menuButton.action = #selector(SWRevealViewController.revealToggle(_:))
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
self.view.addGestureRecognizer(self.revealViewController().tapGestureRecognizer())
tableView.tableFooterView = UIView()
// Do any additional setup after loading the view.
tableView.reloadData()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return bookmarks.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "bookMarkCell", for: indexPath) as? BookMarkTabelCell else { return UITableViewCell() }
cell.priceOfItem.text = "\((bookmarks[indexPath.row].offerPrice) ?? 0)"
cell.depositValue.text = "\(bookmarks[indexPath.row].insuranceValue ?? 0)"
cell.nameOfItem.text = "\(bookmarks[indexPath.row].name ?? " ")"
cell.quantity.text = "\(bookmarks[indexPath.row].quantity ?? 0)"
cell.metookeyerName.text = "\(bookmarks[indexPath.row].accName ?? " ")"
cell.orderDate.text = "\(bookmarks[indexPath.row].createdAt ?? " ")"
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return CGFloat(300)
}
/*
// MARK: - Navigation

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

}
*/
func getAllBookMarks(completion: @escaping CompletionHandler) {
let body1: [String: Any] = [

]
print ("get item by category mmmmmmmmm")
//print("\(URL_ADD_BOOK_MARK)\(itemId)")
print (AuthService.instance.authToken)
print(HeaderForLoggedUser)
Alamofire.request(URL_ALL_BOOK_MARK, method: .post, parameters: nil, encoding: JSONEncoding.default, headers: HeaderForLoggedUser).responseJSON { (response) in
if response.result.error == nil {
completion(true)
// print("login Connection done succes and response data back")
let data = response.data
do {
completion(true)
let result = try JSONDecoder().decode(BookMarksModel.self, from: data!)
self.bookmarks = (result.data?.data!)!
/* DispatchQueue.main.async {
self.tableView.reloadData()
}*/
DispatchQueue.main.async
{
self.tableView.reloadData()
}
} catch {
completion(false)
print(error)
}
}
else {
completion(false)
debugPrint(response.result.error as Any)
}
}
}
}
class BookMarkTabelCell : UITableViewCell
{
@IBOutlet weak var meTooKeyNumber: UILabel!
@IBOutlet weak var metookeyerName: UILabel!
@IBOutlet weak var orderDate: UILabel!
@IBOutlet weak var quantity: UILabel!
@IBOutlet weak var depositValue: UILabel!
@IBOutlet weak var nameOfItem: UILabel!
@IBOutlet weak var priceOfItem: UILabel!
} }
我多次使用reload data()来尝试处理这个问题但不起作用
最佳答案
请尝试这个方法:
func getAllBookMarks(completion: @escaping CompletionHandler) {
let body1: [String: Any] = [
"draw": 3,
"length": 100,
"start": 0
]
print ("get item by category mmmmmmmmm")
//print("\(URL_ADD_BOOK_MARK)\(itemId)")
print (AuthService.instance.authToken)
print(HeaderForLoggedUser)
Alamofire.request(URL_ALL_BOOK_MARK, method: .post, parameters: nil, encoding: JSONEncoding.default, headers: HeaderForLoggedUser).responseJSON { (response) in
if response.result.error == nil {
// print("login Connection done succes and response data back")
let data = response.data
do {
let result = try JSONDecoder().decode(BookMarksModel.self, from: data!)
self.bookmarks = (result.data?.data!)!
completion(true)
} catch {
completion(false)
print(error)
}
}
else {
completion(false)
debugPrint(response.result.error as Any)
}
}
}
}
也许对你有帮助。谢谢。
