我在下面有我的代码,它使用 alamofire http 请求从 api 中提取数据。 https://jsonplaceholder.typicode.com/posts 使用的 API。 我可以获取所有数据,但我想知道的是我想获取所有数据,但我只在集合中显示什么,例如标题等于此"sunt aut facere repellat provident occaecati excepturi optio reprehenderit" 仅显示标题哪个值等于什么我在上面已经说过了。例如,有很多名称值,但我只想显示谁的名字:"Dun"。谢谢。
示例 API
{
"userId": 1,
"id": 1,
"title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
"body": "quia et suscipitnsuscipit recusandae consequuntur expedita et cumnreprehenderit molestiae ut ut quas totamnnostrum rerum est autem sunt rem eveniet architecto"
},
var getAllDetail: [[String:Any]] = [[String:Any]]()
@IBOutlet var collectionView: UICollectionView!
@IBAction func signOutButtonIsPressed(_ sender: Any) {
let appDelegate : AppDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.showLoginScreen()
}
@IBOutlet var signoutButton: UIButton!
var items = [Item]()
override func viewDidLoad() {
super.viewDidLoad()
self.signoutButton.layer.cornerRadius = 3.0
demoApi()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.navigationBar.isHidden = true
self.navigationItem.hidesBackButton = true
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return getAllDetail.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! CollectionCell
if let getTempDetails: [String : Any] = getAllDetail[indexPath.row] {
cell.nameLabel.text = getTempDetails["title"] as? String ?? "" //titleArray[indexPath.row]
}
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
// handle tap events
print("You selected cell #(indexPath.item)!")
if let getTempDetails: [String : Any] = getAllDetail[indexPath.row] {
print("You selected ID #( getTempDetails["userId"] as? String ?? "" )!")
}
}
func demoApi() {
Alamofire.request("https://jsonplaceholder.typicode.com/posts", method: .get, parameters: nil, encoding: JSONEncoding.default, headers: nil).responseJSON { (response:DataResponse<Any>) in
switch(response.result) {
case .success(_):
guard let json = response.result.value as! [[String:Any]]? else{ return}
print("Response (json)")
for item in json {
self.getAllDetail.append(item)
// if let title = item["title"] as? String {
// self.titleArray.append(title)
// }
}
if !self.getAllDetail.isEmpty{
DispatchQueue.main.async {
self.collectionView.reloadData()
}

break
case .failure(_):
print("Error")

参考您的示例响应:
{
"userId": 1,
"id": 1,
"title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
"body": "quia et suscipitnsuscipit recusandae consequuntur expedita et cumnreprehenderit molestiae ut ut quas totamnnostrum rerum est autem sunt rem eveniet architecto"
}
你可以这样使用:-
var dict = response as! NSDictionary
let title = dict.value(forKey: "title")
print(title)
if title == "your text"{
print("Matched")
}else{
print("Not Matched")
}
编辑在您的 Web 中实施响应:-
示例响应:
{
"id": 51,
"name": "uuuuuuuu",
"desc": "ahahah",
"reward": "1.00",
"sched": "2015-01-01T08:00:00+08:00",
"parent": "",
"child": "",
"occurrence": {
"name": "once"
},
"status": "expired",
"date_created": "2018-04-06T11:46:46.131836+08:00",
"date_modified": "2018-04-09T13:16:44.088716+08:00"
}
像这样使用:
let dictOccurence = dict["occurrence"] as! NSDictionary
let strname = dictOccurence["name"]
print(strname!)
if strname == "your text"{
print("Matched")
}else{
print("Not Matched")
}
