How to segue from a Table Cell View in Swift - ios

Question

This is the code i have to far on the main table view view controller I just don't know how to go about transitioning to a new view controller to a selected cell to display more content about whatever cell was selected.
import UIKit
class MainVC: UITableViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet var Table1: UITableView!
var postArray: [[String]] = []
var postSubject = ""
var postDescription = ""
var postDate = ""
override func viewDidLoad() {
super.viewDidLoad()
fetchData()
}
func fetchData() {
println("success1")
postArray = []
let httpMethod = "GET"
let timeout = 15
let urlAsString = "http://cgi.soic.indiana.edu/~team12/main_requests.php"
let url = NSURL(string: urlAsString)!
let urlRequest = NSMutableURLRequest(URL: url,
cachePolicy: .ReloadIgnoringLocalAndRemoteCacheData,
timeoutInterval: 15.0)
urlRequest.HTTPMethod = httpMethod
let queue = NSOperationQueue()
println("success2")
NSURLConnection.sendAsynchronousRequest(urlRequest,
queue: queue,
completionHandler: {(response: NSURLResponse!,
data: NSData!,
error: NSError!) in
if data.length > 0 && error == nil{
let html = NSString(data: data, encoding: NSUTF8StringEncoding)
} else if data.length == 0 && error == nil{
println("Nothing was downloaded")
} else if error != nil{
println("Error happened = \(error)")
}
if data.length > 0 && error == nil {
let html = NSString(data: data, encoding: NSUTF8StringEncoding)
var newArrayofDicts : NSMutableArray = NSMutableArray()
var arrayOfDicts : NSMutableArray? = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error:nil) as? NSMutableArray
println("successmutable")
if arrayOfDicts != nil {
for item in arrayOfDicts! {
if var dict = item as? NSMutableDictionary{
if dict["subject"] != nil{
self.postSubject = dict["subject"] as String
self.postDescription = dict["subject"] as String
self.postDate = dict["date"] as String
self.postArray.append([self.postSubject,self.postDescription,self.postDate])
println("successpost")
}
}
}
}
}
}
)
sleep(1)
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
fetchData()
tableView.reloadData()
println("successanime")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return postArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
println("successoverride")
let cell = tableView.dequeueReusableCellWithIdentifier("UpdateCell", forIndexPath: indexPath)
as UITableViewCell
println("successupdatecell")
cell.textLabel.text = postArray[indexPath.row][1]
cell.detailTextLabel?.text = postArray[indexPath.row][2]
println("success3")
return cell
}

Try this method
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
...
}
Or you can do it straight in the storyboard by ctrl dragging the prototype cell to the next viewController.
Hope this helps!!
Edit
If you want to segue to the next view controller programmatically, then you can do either:
performSegueWithIdentifier("yourSegueName", sender: nil)
Or:
presentViewController(nextViewController, animated: true, completion: nil)
