从firebase加载数据后出现问题,当我调用重新加载数据时,表视图中填充了新的列表数据,但全为白色,如果单击,则可以正确获取数据值。
如果我使用静态数据,则一切正常。
有什么建议吗?谢谢!
private func loadUniversity(url: String) {
let configuration = URLSessionConfiguration.ephemeral
let session = URLSession(configuration: configuration)
let url = URL(string: url)!
let task = session.dataTask(with: url) {
(data, response, error) in
guard let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200, let data = data else {
return
}
do {
let decoder = JSONDecoder()
let university = try decoder.decode([UniversityJSON].self, from: data)
for item in university {
self.universityArray.append(University(name: item.university_name.trim()))
}
let queue = OperationQueue.main
queue.addOperation {
self.currentUniversityArray = self.universityArray
print(self.currentUniversityArray)
self.table.reloadData()
}
} catch {
print("Error info: \(error)")
}
}
task.resume()
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as? UniversityCell else {
return UITableViewCell()
}
cell.name.text = currentUniversityArray[indexPath.row].name
return cell
}
最佳答案
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as? UniversityCell else {
return UITableViewCell()
}
cell.name.text = currentUniversityArray[indexPath.row].name
// Put this background Color
cell.backgroundColor = .clear
return cell
}
