Ios development training presentation
- 1. IOS Apps development training
- 2. Introducing an IOS ● iOS is the operating system that runs on iPad, iPhone, and iPod touch devices. ● The operating system manages the device hardware and provides the technologies required to implement native apps. ● The operating system also ships with various system apps, such as Phone, Mail, and Safari, that provide standard system services to the user. ● The iOS Software Development Kit (SDK) contains the tools and interfaces needed to develop, install, run, and test native apps that appear on an iOS device’s Home screen. ● Native apps are built using the iOS system frameworks and Objective-C, Swift language and run directly on iOS. ● They reside next to other system apps, and both the app and any user data is synced to the user’s computer through iTunes.
- 3. Developer Certificate ● Apple Developer Program membership is required to request, download, and use signing certificates issued by Apple. ● You must also be the Team Agent or an admin of your development team to request distribution certificates used for submitting apps to the App Store or Mac App Store. ● In most cases, Xcode is the preferred method to request and install digital certificates for iOS and OS X. ● However, to request certificates for the Apple Push Notification service, Passbook, Mobile Device Management (MDM), and Safari extensions, you will need to request and download them from Certificates, Identifiers & Profiles in your account on the developer website.
- 4. Steps for creating developer certificate ● Go to: http://developer.apple.com/programs/ios and click on "Enroll Now". ● Click "Continue" ● Select option to create new account under New Apple Developer and on the following screen choose to sign up as an individual. ● Complete the personal profile information. ● Follow the instructions to complete your purchase. You will receive a confirmation email at that time. ● About 24 hours later, you will receive an activation email from Apple. Your Developer Account is not ready until after you click the link inside that email! ● Sign into Apple's Member Center with your Apple ID here: https://developer.apple.com/membercenter/index.action.
- 5. Certificate Signing Request (CSR) ● In public key infrastructure (PKI) systems, a certificate signing request (also CSR or certification request) is a message sent from an applicant to a certificate authority in order to apply for a digital identity certificate. Steps for Install CSR ● Open Keychain Access on your Mac (located in Applications/Utilities). ● Open Preferences and click Certificates. ● Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority. ● Select the options “Saved to disk” and “Let me specify key pair information” and click Continue. ● Specify a filename and click Save.
- 6. Provisioning profile ● A provisioning profile is a collection of digital entities that uniquely ties developers and devices to an authorized iPhone Development Team and enables a device to be used for testing. ● A Development Provisioning Profile must be installed on each device on which you wish to run your application code. Two types of Provisioning profile ● Development Provisioning profile ● Distribution Provisioning profile
- 7. Creating Development profile ● Sign in to developer.apple.com/account, and click Certificates, IDs & Profiles. ● In the drop down menu in the top left corner, verify that iOS, tvOS, watchOS is selected. ● Select provisioning profile, click + ● Select iOS app development and click continue. ● Select an App id to associate with the provisioning profile and click continue. ● Select one or more devices to include in the provisioning profile and click continue. ● Provide name for the profile and click continue. ● Click download and install the provisioning profile.
- 8. App Id and Bundle Id ● An App ID is a two-part string used to identify one or more apps from a single development team. ● A bundle identifier lets iOS and macOS recognise any updates to your app. Your bundle ID must be registered with Apple and be unique to your app. Bundle IDs are app-type specific (either iOS or macOS). The same bundle ID cannot be used for both iOS and macOS apps. Create App Id and Bundle Id ● Click the Add button (+) in the upper-right corner. ● Enter a name or description for the App ID in the Description field. ● Select Explicit App ID and enter the app’s bundle ID in the Bundle ID field. An explicit App ID exactly matches the bundle ID of an app you’re building :- for example,com.example.ajohnson. ● Select the corresponding checkboxes to enable the app services you want to use. ● Click Continue, Review the registration information, click Register and Click Done.
- 9. Distribution Provisioning profile ● Sign in to developer.apple.com/account, and click Certificates, IDs & Profiles. ● Under Provisioning Profiles, select All ● Click the Add button (+) in the upper-right corner. ● Select Ad Hoc as the distribution method, and click Continue. ● Choose the App ID you used for development, which matches your bundle ID, from the App ID pop-up menu, and click Continue. ● Select the distribution certificate you want to use, and click Continue. ● Select the devices you want to use for testing, and click Continue. ● Enter a profile name, and click Continue. ● Wait while your developer account generates the provisioning profile and Click Done.
- 10. Swift Language • Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C (ObjC) code written for Apple products. • Development of Swift started in July 2010 by Chris Lattner, with the eventual collaboration of many other programmers at Apple. • Swift took language ideas "from ObjectiveC, Rust, Haskell, Ruby, Python, C#, CLU, etc. • June 2, 2014, the Apple Worldwide Developers Conference (WWDC) application became the first publicly released app written in Swift.
- 11. UI Controls in IOS • Text Fields - It is an UI element that enables the app to get user input. • Buttons - It is used for handling user actions. • Label - It is used for displaying static content. • Toolbar - It is used if we want to manipulate something based on our current view. • Status Bar - It displays the key information of device. • Navigation Bar - It contains the navigation buttons of a navigation controller, which is a stack of view controllers which can be pushed and popped.
- 12. • Table View - It is used for displaying scrollable list of data in multiple rows and sections. • Split View - It is used for displaying two panes with master pane controlling the information on detail pane. • Text View - It is used for diplaying scrollable list of text information that is optionally editable. • View Transition - It explains the various view transitions between views. • Pickers - It is used for displaying for selecting a specific data from a
- 13. How to create a project • Open a xcode. • Click File > New > Project in Menu bar. • Select single view app in template and click next. • Enter a project name, Organisation name, Organisation Identifier and choose language then click next. • Project store somewhere in our machine.
- 14. Basics in Swift Constants and Variables • Constants and variables associate a name with a value of a particular type. • The value of a constant can’t be changed once it’s set, whereas a variable can be set to a different value in the future. Declaring Constants and Variables • let maximumNumberOfLoginAttempts = 10 • var currentLoginAttempt = 0 • var x = 0.0, y = 0.0, z = 0.0 • var welcomeMessage: String welcomeMessage = “Hello"
- 15. Printing print(friendlyWelcome) print("The current value of friendlyWelcome is (friendlyWelcome)”) Int let meaningOfLife = 42 Boolean let orangesAreOrange = true let turnipsAreDelicious = false String let someString = "Some string literal value” Array var shoppingList = ["Eggs", “Milk"] var shoppingList: [String] = ["Eggs", "Milk"]
- 16. Hello World! Place a button in story board. Assigning a button function as “IBAction func declare()” Inside that button function, placed the alert view. @IBAction func showMessage() let alertController = UIAlertController(title: "Welcome to My First App",message: "Hello World", preferredStyle: UIAlertControllerStyle.alert)alertController.addAction(UIAlertAction( title: "OK", style: UIAlertActionStyle.default, handler: nil)) present(alertController, animated: true, completion: nil) }
- 17. UITableView • Tableview controller placing in story board. • Place tableview cell over the tableview. • Declare the tableview in view controller file. class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", “Goat”] let cellReuseIdentifier = “cell" @IBOutlet var tableView: UITableView! override func viewDidLoad() { super.viewDidLoad() self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier) tableView.delegate = self tableView.dataSource = self }
- 18. func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return self.animals.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell! cell.textLabel?.text = self.animals[indexPath.row] return cell } func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { print("You tapped cell number (indexPath.row).”) } }
- 19. Soap API In Soap API we using delegate methods for Parsing data. Soap API like a XML format. Delegate methods for NSURLConnection: func connection(connection: NSURLConnection!,didReceiveResponse response: NSURLResponse!) { } func connection(connection: NSURLConnection!, didReceiveData data: NSData!) { } func connection(connection: NSURLConnection, didFailWithError error: NSError) { } func connectionDidFinishLoading(connection: NSURLConnection!) { }
- 20. Delegate methods for Parser: func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String]) { } func parser(parser: NSXMLParser, foundCharacters string: String) { } func parser(_ parser: XMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?){ }

- 22. Submitting Apps in Apps store • App id • Distribution Certificate • Provisioning Profile • Build Settings • Deployment Target • Icons • Screenshots • Submission Preparation in Basic Information • Price and Availability • Metadata • Uploading the App Binary • Waiting
- 23. App ID Every application needs an App ID or application identifier. Distribution Certificate To submit an application to the App Store, you need to create an iOS provisioning profile for distribution Provisioning Profile Create an iOS provisioning profile for distributing your application through the App Store. Build Settings With the App ID, distribution certificate, and provisioning profile in place, it is time to configure your target's build settings in Xcode Deployment Target The minimum version of the operating system that the application can run on. Icons Need to make sure that your application ships with the correct sizes of the artwork.
- 24. Screenshots • Each application can have up to five screenshots and three previews, and you must provide at least one. • If you are developing a universal application, then you need to provide separate screenshots for each device. Basic Information in Submission Preparation • The App Name, which needs to be unique, is the name of your application as it will appear in the App Store. • The SKU Number is a unique string that identifies your application. I usually use the application's bundle identifier. • The last piece of information is the Bundle ID of your application. Price and Availability Apple works with price tiers so that you don't have to specify a price for each country that Apple operates.
- 25. Uploading the App Binary • To submit your app, you need to create an archive. • You can only create an archive by building your application on a generic device. • If you select the iOS Simulator in the active scheme, • you will notice that the Archive option in Xcode's Product menu is grayed out. • Connect an iOS device to your Mac, select it in the active scheme, and select Archive from Xcode's Product menu. • If all went well, you should now have an archive, and Xcode's Organizer should automatically open and show you the archive you just created. • Select the archive from the list and click the Upload to App Store. • Button on the right. The application binary is then uploaded to Apple's servers.
- 26. Waiting • If the submission process went without problems, your application's status will change to Waiting for Review. • It takes several days for Apple to review your app, and the time it takes tends to fluctuate over time.
- 27. Thank You.
