How to send data to table view with Alamofire And SwiftyJSON

I have a (large amount) of data that I want to send to Table View with alamofire and siftyJSON

web request :

let postEndPoint :String = "http://jsonplaceholder.typicode.com/posts/"


code Alamofire and SwiftyJSON:

override func viewDidLoad() {
super.viewDidLoad()

Alamofire.request(.GET, postEndPoint).responseJSON { response in
// handle json
guard response.result.error == nil else{
print("error calling Get on /posts/1")
print(response.result.error)
return

}


if let value: AnyObject = response.result.value{

let post = JSON(value)
// for i in 0...post.count{
if let title = post["data"].arrayValue as? [JSON]{
self.datas = title
self.tableView.reloadData()
print("the title is :\(title)" )
}else{

print("eror parsing /post/1 ")

}

// }

}
}

}


code table view :

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell")!
var dict = datas[indexPath.row]
cell.textLabel?.text = dict["userId"] as? String
cell.detailTextLabel?.text = dict["id"] as? String
return cell
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return datas.count
}


}

I am trying to post some json data to table view but when I send the data it returns nothing . why??

Answer

this is the code working for me. main thing is you have to reload the table at the end of api calling. and you are printing nuber as a string so you have to convert it to string

enter image description here

my code is here

import UIKit

class customcell: UITableViewCell {

@IBOutlet weak var lbl1: UILabel!

@IBOutlet weak var lbl2: UILabel!

}

class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {

@IBOutlet weak var tabledata: UITableView!
let postEndPoint :String = "http://jsonplaceholder.typicode.com/posts/"
var arr:NSMutableArray = NSMutableArray()
override func viewDidLoad() {
    super.viewDidLoad()
    web()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("customcell") as! customcell

    let dict = arr[indexPath.row] as! NSDictionary
    print(dict)

   print(dict["userId"])
    cell.lbl1?.text = String (dict["userId"]! )
    cell.lbl2?.text = String (dict["id"]! )

    return cell

}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return arr.count
}
func web()
{
    request(.GET, postEndPoint, parameters: nil, encoding:
        .JSON).responseJSON { (response:Response<AnyObject, NSError>) -> Void in

            print(response.result.value)
            if (response.result.value != nil)
            {
                self.arr = (response.result.value) as! NSMutableArray

            }

            self.tabledata.reloadData()
    }
}

}
