How to use multiple UITableView in single view Controller in iOS - Swift - ios

Question

I am new to iOS development. Currently, I am working on a project in which I use more than two UITableViews in a single view controller, but both data sources come from server one by one. When the first api hit, it shows the result, but after select item from that list I am unable to show the response in list.
Here is my code:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
print("sdfsdfsf")
var count:Int?
if tableView == self.pat_search_listview {
count = serach_data.count
}
else if tableView == self.visit_listview {
count = all_vist_data.count
}
return count!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
if tableView == self.pat_search_listview {
cell.textLabel?.text = serach_data[indexPath.row].name + " " + serach_data[indexPath.row].id
}
else if tableView == self.visit_listview {
print("second listview")
cell.textLabel?.text = all_vist_data[indexPath.row].date
}
return cell
}

Answer 1

check the Outlet connections for both tableViews... both shouldn't be nil in viewDidLoad
in viewDidLoad:
self.pat_search_listview.dataSource = self;
self.visit_listview = self;
self.pat_search_listview.tag = 0
self.visit_listview.tag = 1
in
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView.tag == 0
...
else
...

Make sure to set delegate and data source and don't forget to reload the table after adding/updating the arrays.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
if tableView == self.pat_search_listview
{
return serach_data.count/*pat_search_listview's Array count*/
}
else if tableView == self.visit_listview
{
return all_vist_data.count/*visit_listview Array count*/
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell()
if tableView == self.pat_search_listview
{
cell.textLabel?.text = serach_data[indexPath.row].name + " " + serach_data[indexPath.row].id
}
else if tableView == self.visit_listview
{
print("second listview")
cell.textLabel?.text = all_vist_data[indexPath.row].date
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
if tableView == self.pat_search_listview
{
//--- Item at index from pat_search_listview
}
else if tableView == self.visit_listview
{
print("second listview")
//--- Item at index from visit_listview
}
}
