Sample Code :

import UIKit

import Alamofire

// Import your library

    override func viewDidLoad() {

        

        super.viewDidLoad()

        

        Alamofire.request(.GET, url_maj).responseJSON { response in

            if let JSON = response.result.value {

                let jsonObj = JSON as? NSDictionary

                let data_ = jsonObj!["data"] as! NSArray

                for item in data_ {

                    let MS04Key = item["MS04Key"]!

                    let MajorName = item["MajorName"]!

                    print("MS04Key is \(MS04Key!)")

                    print("MajorName is \(MajorName!)")

                }

            }

        }

        

    }


for POST

Alamofire.request(.POST, "http://xxxxx/xxxxx/xxxxx/get", parameters: ["xxType": "dradr","xxName": "Test Attaching","xxxcusName": "THE LIGHT","fxxolderName": "xout00001t","xxsubmitterName": "METEST"]).responseJSON { response in

            if let JSON = response.result.value {

// Your Logic

}

First Responder & Keyboard Handling

First Responder & Keyboard Handling

Hi!

In IOS the First Responder has play a small role. But it is very important to handle the applications where keyboard is shown.

// Import basic UIKit Package

import UIKit

// Implement UITextFieldDelegate

class Sample_VC: UIViewController, UITextFieldDelegate 

{

// create UITextfield

@IBOutlet weak var et_un: UITextField!

    

@IBOutlet weak var et_pass: UITextField!

override func viewDidLoad() {

        super.viewDidLoad()

// Should fix delegate for self

et_un.delegate = self

et_pass.delegate = self

// Methods for Navigate UITextfield Up & Down on Main view while Typing 

NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillShow:"), name:UIKeyboardWillShowNotification, object: nil);

        NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillHide:"), name:UIKeyboardWillHideNotification, object: nil);

}

    func keyboardWillShow(sender: NSNotification) {

        self.view.frame.origin.y -= 150

    }

    

    func keyboardWillHide(sender: NSNotification) {

        self.view.frame.origin.y += 150

    }

// Implementation Method for UITextField Handl

func textFieldShouldReturn(textField: UITextField) -> Bool {

        if(textField == et_un)

        {

// Move to next UITextField

            et_pass.becomeFirstResponder()

        }

        else if(textField == et_pass)

        {

// Resign the FirstResponder

            et_pass.resignFirstResponder()

        }

        return false

    }

}

Custom UIButton In SWIFT

Hi!

The IOS developers are begin to move from the existing Objective-C into Brand New Sift.
In our existing Objective-C we have lot of library to make a customization .  Likewise in SWIFT also we can customize the UI. But if googled we can find very few amount of results only.

Now i have create a custom UIButton with Customize Border, Color, Background, Adjust the Button size depends on button Title & Padding around the title of Button.

Swift Class for Custom UIButton

import UIKit

import Foundation

class Btn: UIButton {

// init method for UIButton

    required init(coder aDecoder: NSCoder) {

// Override the Super class of UIButton

        super.init(coder:aDecoder)

// Make padding around the button 

        self.contentEdgeInsets = UIEdgeInsets(top: 2.0, left: 5.0, bottom: 2.0, right: 5.0)

// To adjust the button size depends on the button Title

        self.titleLabel?.adjustsFontSizeToFitWidth = true

// Minimum Label size 

        self.titleLabel!.minimumScaleFactor = 0.5

// Set the Radius size as 5.0

        self.layer.cornerRadius = 5.0;

// Set the Border Color & With

        self.layer.borderColor = UIColor.whiteColor().CGColor

        self.layer.borderWidth = 1.5

// Set the Background Color

        self.backgroundColor = UIColor.redColor()

// Set the Tint Color

        self.tintColor = UIColor.orangeColor()

    }

} 


On your UIButton set the class as the Custom UIButton Class That's all..,

Enjoy!..,

Thank You!

Have A Happy Day..,

JSON Parsing in IOS using SWIFT

JSON Parsing in IOS using SWIFT

Hi!


About JSON!

JSON is a Very light weight framework to transfer data when compare with XML.

JSON in IOS!

Like Android, IOS also can transfer the data very fast and securely in JSOn format.

Today i am going to give an example about how to transfer the JSON data to IOS by using the Brand new SWIFT language.

Step 1:

     Create a new ios project using your XCODE. delete the default story board and its ViewController.

Step 2:

   On your StoryBoard  Place a Table View Controller, on your CELL change the Identifier name as "cell"

Step 3:

    Create a COcoa Touch new class with SubClass of UITableViewController after create the class configure as Custom Class of your StoreBoard Table View Controller.

Sample JSON Data :


{
    "Data": [
        {
            "AccountId": "xxxxxxxxxxxxxxxx",
            "AccountName": "xxxxxxxxxxxxxxxx",
            "Topic": "xxxxxxxxxxxxxxxx",
            "Discipline": "xxxxxxxxxxxxxxxx",
            "Source": "xxxxxxxxxxxxxxxx",
            "Email": "xxxxxxxxxxxxxxxx",
            "PhoneNumber": "xxxxxxxxxxxxxxxx",
            "URL": "xxxxxxxxxxxxxxxx"
        },
        {
            "AccountId": "xxxxxxxxxxxxxxxx",
            "AccountName": "xxxxxxxxxxxxxxxx",
            "Topic": "xxxxxxxxxxxxxxxx",
            "Discipline": "xxxxxxxxxxxxxxxx",
            "Source": "xxxxxxxxxxxxxxxx",
            "Email": "xxxxxxxxxxxxxxxx",
            "PhoneNumber": "xxxxxxxxxxxxxxxx",
            "URL": "xxxxxxxxxxxxxxxx"
        }
]
}

Step 4:


Create an Array to store your value

var TableData:Array<String>=Array<String>()

    On ViewDidLoad() method call your service

url_json_data("http://xxxxxx/xxxx/xxxx/xxxx/xxxxxx/xx")

On numberOfSectionsInTableView() Method Return "1" 

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

        // #warning Potentially incomplete method implementation.

        // Return the number of sections.

        return 1

    }

On tableView() Method

return your array value

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        // #warning Incomplete method implementation.

        // Return the number of rows in the section.

        return TableData.count

    } 

On tableView() for cell function do the fallowing

the "cell" is the name what you have assigned in the step 2

   override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell

        cell.textLabel?.text=TableData[indexPath.row]

        return cell

    }

Method To Parsing the JSON

    func url_json_data(url:String)

        

    {

        

        let httpMethod = "GET"

        

        let timeout = 15

        

        let url = NSURL(string: url)

        

        let urlRequest = NSMutableURLRequest(URL: url!,cachePolicy: .ReloadIgnoringLocalAndRemoteCacheData,timeoutInterval: 15.0)

        

        let queue = NSOperationQueue()

        

        NSURLConnection.sendAsynchronousRequest(

            

            urlRequest,

            

            queue: queue,

            

            completionHandler: {(response: NSURLResponse!,

                

                data: NSData!,

                

                error: NSError!) in

                

                if data.length > 0 && error == nil{

                    

                    let json = NSString(data: data, encoding: NSASCIIStringEncoding)

                    

                    self.json_data_extractor(json!)

                    

                }else if data.length == 0 && error == nil{

                    

                    println("Nothing was downloaded")

                    

                } else if error != nil{

                    

                    println("Error happened = \(error)")

                    

                }

                

            }

            

        )

        

    }

Method to extract the JSON Data

    func json_data_extractor(data:NSString)

        

    {

        

        var parseError: NSError?

        

        let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!

        

        let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &parseError)

        

        if (parseError == nil)

            

        {

            

            if let countries_list = json as? NSDictionary

                

            {

                if let Data_obj_list = countries_list["Data"] as? NSArray

                {

                    println(Data_obj_list.count)

                    for(var i=0; i < Data_obj_list.count; i++)

                    {

                        if let country_obj = Data_obj_list[i] as? NSDictionary

                        {

                            if let country_name = country_obj["AccountName"] as? String

                                

                            {

                                

                                if let country_code = country_obj["Discipline"] as? String

                                    

                                {

                                    if let email_id=country_obj["Email"] as? String

                                    {

                                         TableData.append(country_name + " , " + country_code + " , " + email_id)

                                    }

                                    

                                }

                                

                            }

                        }

                        

                    }

                }

                

            }

            

        }

        

        refresh_table();

        

    }

Method to refresh the Table

   func refresh_table()

        

    {

        

        dispatch_async(dispatch_get_main_queue(), {

            

            self.tableView.reloadData()

            

            return

            

        })

        

    }

Thats All!

Enjoy The Code!
