How to put JSON response to a tableview - arrays

Question

I have a model Users and in that model
static func getUsers() -> Single<[Users]> {
let path = API.Path.users.details
let params: [String: Any] = [
"utcOffset": TimeZone.current.utcOffset
]
return API.requestMany(path: path, method: .get, parameters: params)
}
i declare it like this
let sus = [Users]()
And in my cellForRowAt i have this
Users
.getUsers()
.do(onError: { [weak self] error in
print(error.localizedDescription)
})
.do(onSuccess: { [weak self] userNames in
print(userNames)
cell.name.text = userNames[indexPath.row].name
})
.subscribe()
.disposed(by: rx.disposeBag)
That code is not being called so my tableview is empty but when i tried putting it in ViewDidLoad its being called and triggering my print statement print(userNames)

Answer 1

Your code isn't being called because nothing is calling the function that you put the code in. It works in viewDidLoad because that function is being called.
Based on your description I would expect code that looks like this in your viewDidLoad()
Users.getUsers()
.asObservable()
.bind(to: tableView.rx.items) { tableView, index, user in
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: IndexPath(index: index)) as! MyTableViewCell
cell.configure(for: user)
return cell
}
.disposed(by: disposeBag)
Based on your comments, I've come to understand that you only want to use Rx for your network calls. In that case, the solution should look like this:
final class ExampleViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var tableView: UITableView!
private var users: [User] = []
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
_ = User.getUsers()
.subscribe(
onSuccess: { [weak self] in
self?.users = $0
self?.tableView.reloadData()
},
onError: { error in
print("handle network error here")
}
)
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 44
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
users.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! MyTableViewCell
cell.configure(for: users[indexPath.row])
return cell
}
}
final class MyTableViewCell: UITableViewCell {
func configure(for user: User) {
print("configure your cell here")
}
}
struct User {
static func getUsers() -> Single<[User]> { fatalError("Implement me") }
}
