Update UITableView Data from server - did not work - ios

Question

I am struggling with UITableView's data fetching and/or reloadData() from server. I am creating this app to check user's pronunciation via server. The data parsing came out well (I checked with print statement) but it won't update to my table cell.
I created a dictionary to store loaded Data:
var summaryDict = ["Overall Score" : "Score", "Words" : "Score", "Syllables": "Score", "Phonemes": "Score"]
var summaryArray = ["Overall Score", "Words", "Syllables", "Phonemes"]
I did also update dict values after parsing JSON data:
.responseJSON { response in
switch response.result {
case .success:
do{
let json = try JSON(data: response.data!)
if let data = response.data {
if let summaryData = self.parseJSON(data) {
DispatchQueue.main.async {
print(summaryData)
self.summaryDict["Overall Score"] = summaryData.summaryScore
self.summaryDict["Words"] = summaryData.wordScore
self.summaryDict["Syllables"] = summaryData.syllableScore
self.summaryDict["Phonemes"] = summaryData.phoneScore
print(self.summaryDict)
self.delegate?.didUpdateScore(self, score: summaryData)
}
}
}
let statusJson = json["status"].string
if statusJson == "success" {
completion("success")
}
else { completion("error parseJSON") }
} catch {
print(error.localizedDescription)
}
case .failure(let encodingError):
print("error:\(encodingError)")
}
}
Over my ViewController I did also added tableview datasource extension:
extension FreeTrialViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return audioSender.summaryDict.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "SummaryCell", for: indexPath) as! SummaryCell
cell.summaryLabel.text = self.audioSender.summaryArray[indexPath.row]
cell.summaryScore.text = self.audioSender.summaryDict[self.audioSender.summaryArray[indexPath.row]]
return cell
}
}
I tried to put reloadData() everywhere I can or DispatchQueue.main.async every now and then yet the cell did not update.
EDITED: Include delegate at view controller:
extension FreeTrialViewController: AudioSenderDelegate {
func didFailWithError(_ error: Error) {
print("parsing audio delegate error: \(error)")
}
func didUpdateScore(_ audioSender: AudioSender, score: SummaryData) {
// updateTable()
summaryTable.reloadData()
}
}
Here's the end result after multiple tries:
(when I took the picture I mistakenly deleted 1 char from the "Overall Score" from the array so the Overall Score disappeared but when I corrected it it goes for 4 "Score".
What I want in the table:
Overall Score: 97
Words: 96.8
Syllable: 96.9
Phonemes: 97.0
What really showed up:
EDITED:
I shall include here the func that I call out the table:
Pretty sure inside the finish recording is the parse data.
I did try adding the guard as:
guard audioSender.summaryDict["Words"] != "Score" else { return }
Yet it would come out blank.

Answer 1

It seems like I forgot to add the line:
audioSender.delegate = self
so the data won't reload.
Thanks so much for all of your help.
Such a shame on me :).
