我想填充我的UITableView
與我從GET請求收到的一些數據。我不知道爲什麼,但如果在我的numberOfRowsInSection
中,我返回一個特定值(例如8)它代表信息。若y回到我的數組被要求填寫的值,則UITableView
不添加任何行:TableView不顯示數據
class DashboardTableViewController: UITableViewController {
var userData = [String]()
var secondUserData = [String]()
var name: String = ""
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
}
/* This function gets the user account information from a JSON in a simple request */
private func loadUserData(completion: @escaping (_ myArray: [String]) -> Void) {
let session = Twitter.sharedInstance().sessionStore.session()
let client = TWTRAPIClient.withCurrentUser()
let userInfoURL = "https://api.twitter.com/1.1/users/show.json"
let params = ["user_id": session?.userID]
var clientError : NSError?
let request = client.urlRequest(withMethod: "GET", url: userInfoURL, parameters: params, error: &clientError)
client.sendTwitterRequest(request) { (response, data, connectionError) -> Void in
if connectionError != nil {
print("Error: \(connectionError)")
}
do {
let json = JSON(data: data!)
if let userName = json["name"].string,
let description = json["description"].string,
let followersCount = json["followers_count"].int,
let favouritesCount = json["favourites_count"].int,
let followingCount = json["friends_count"].int,
let lang = json["lang"].string,
let nickname = json["screen_name"].string {
self.userData.append(userName)
self.userData.append(nickname)
self.userData.append(String(followersCount))
self.userData.append(String(followingCount))
self.userData.append(String("22"))
self.userData.append(lang)
self.userData.append(description)
self.userData.append("No country")
completion(self.userData)
}
}
}
}
/* This closure helps us to fill the labels once the request has been finished in loadUserData */
func manageUserData(label: UILabel, index: Int) {
loadUserData {
(result: [String]) in
label.text = result[index]
}
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return self.userData.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let rowNumber = indexPath.row
let cellIdentifier = "TableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TableViewCellController else {
fatalError("The dequeued cell is not an instance of TableViewCellController.")
}
switch rowNumber {
case 0:
cell.titlePlaceholder.text = "Name:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 1:
cell.titlePlaceholder.text = "Nickname:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 2:
cell.titlePlaceholder.text = "Followers:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 3:
cell.titlePlaceholder.text = "Following:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 4:
cell.titlePlaceholder.text = "Tweets:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 5:
cell.titlePlaceholder.text = "Language:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 6:
cell.titlePlaceholder.text = "Biography:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
case 7:
cell.titlePlaceholder.text = "Country:"
manageUserData(label: cell.valuePlaceholder, index: rowNumber)
default:
cell.titlePlaceholder.text = "?"
cell.valuePlaceholder.text = "?"
}
return cell
}
}
任何想法,爲什麼發生這種情況? 非常感謝!
更新!
我解決了這個問題,在loadUserData()函數內的completion()之後添加self.tableView.reloadData()。希望能幫助到你!
添加覆蓋func tableView(_ tableView:UITableView,cellForRowAt indexPath:IndexPath)開始處的斷點 - > UITableViewCell {' 檢查此方法是否被稱爲 – Maxime
這是關於您的請求。嘗試在'let json = JSON(data:data!)'後面打印你的json,看看會發生什麼 – GIJOW
它只有在我在override func tableView中返回一個特定值時纔會執行這兩個操作(_ tableView:UITableView,numberOfRowsInSection section:Int ) - > Int –
