i have tried loads of different methods, normally the code i use works. However in this case im not sure if its to do with the code from the tutorial that i have used. They have used https instead of http. I have tried different methods im not sure what to do! any advice would be appreciated.
@IBAction func signinTapped(sender : UIButton) {
let username:NSString = txtUsername.text!
let password:NSString = txtPassword.text!
if ( username.isEqualToString("") || password.isEqualToString("") ) {
let alertView:UIAlertView = UIAlertView()
alertView.title = "Sign in Failed!"
alertView.message = "Please enter Username and Password"
alertView.delegate = self
alertView.addButtonWithTitle("OK")
alertView.show()
} else {
do {
let post:NSString = "username=\(username)&password=\(password)"
NSLog("PostData: %@",post);
let url = NSURL(string:"http://")
let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)!
let postLength:NSString = String( postData.length )
let request:NSMutableURLRequest = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.HTTPBody = postData
request.setValue(postLength as String, forHTTPHeaderField: "Content-Length")
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
var reponseError: NSError?
var response: NSURLResponse?
var urlData: NSData?
do {
urlData = try NSURLConnection.sendSynchronousRequest(request, returningResponse:&response)
} catch let error as NSError {
reponseError = error
urlData = nil
}
if ( urlData != nil ) {
let res = response as! NSHTTPURLResponse!;
NSLog("Response code: %ld", res.statusCode);
if (res.statusCode >= 200 && res.statusCode < 300)
{
let responseData:NSString = NSString(data:urlData!, encoding:NSUTF8StringEncoding)!
NSLog("Response ==> %@", responseData);
//var error: NSError?
let jsonData:NSDictionary = try NSJSONSerialization.JSONObjectWithData(urlData!, options:NSJSONReadingOptions.MutableContainers ) as! NSDictionary
let success:NSInteger = jsonData.valueForKey("success") as! NSInteger
//[jsonData[@"success"] integerValue];
NSLog("Success: %ld", success);
if(success == 1)
{
NSLog("Login SUCCESS");
let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
