Repeating values on a table view cells Error from API response - ios

Question

I have a view (lets call it View 1) with a button on it. When the button is clicked I make a GET http request to my API. It sends back an array of objects.
Currently what I am trying to do is that when a user presses the button on view 1 the response data is passed to view 2 which is a tableView. And then fill up the table view cells with the returned data.
I am passing the returned JSON response from view 1 to view 2 like this:
dispatch_async(dispatch_get_main_queue()) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("BioView") as! BioTableViewController
vc.bioArray = parseJSON
self.presentViewController(vc, animated: true, completion: nil)
}
Where parseJSON contains the returned JSON response.
In View 2 I have the following:
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return self.bioArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("bioCell", forIndexPath: indexPath) as! UITableViewCell
// Configure the cell...
if bioArray.count > 0 {
let weatherSummary: AnyObject = bioArray[indexPath.row]
for x in bioArray {
if let id = x["employeeName"] as? String{
cell.textLabel?.text = id
}
}
}
return cell
}
The Issue:
The table view keeps repeating the last value in the returned JSON data. see below:
My Question:
How can stop the value from repeating and show all the values from the response data and when I click on the a tableview cell it goes to another view and shows all the details related to the clicked on cell.

Answer 1

You don't need to use for loop(because of it, table view keeps repeating value I guess). cellForRowAtIndexPath will do the same for you. Just try the code below :
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("bioCell", forIndexPath: indexPath) as! UITableViewCell
// Configure the cell...
let weatherSummary: AnyObject = bioArray[indexPath.row]
if let id = weatherSummary["employeeName"] as? String //Dont know the exact syntax.
{
cell.textLabel?.text = id
}
return cell
}
And to get rid of if bioArray.count > 0 condition you can do like
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return self.bioArray.count ?? 0 //This will return 0 rows if bioArray is empty.
}
Hope this will help!
