Develop a Custom Keyboard in iOS 9 & Swift 2 - 4 Keyboards!

Begin programming your keyboard by building a basic keyboard and learning its functionalities and rules. A button inserts the text label into text field, then set up the Xcode project.

Create a new Xcode project as a single view application in Swift for iPhone, add a centered text field, and set up auto layout to test a custom keyboard.

Organize the code by creating an add next button function and loading it into the view to keep the keyboard working as before.

Programmatically add a hello button to the custom keyboard, wiring it to insert the text hello into the selected text field via the text document proxy, and center it.

Add a delete button and a hide keyboard button to your custom keyboard, wiring a delete text action with the text document proxy's deleteBackward and positioning the button with constraints.

Add a hide button to the first custom keyboard, wiring it to the dismiss keyboard action and updating constraints to the top right, then test hiding and reopening the keyboard.

Build a calculator keyboard that performs simple mathematics and submits the computed result into the selected text, as this section prepares for storyboard design and keyboard layout.

Set up a Xcode project as a single view app with a calculator keyboard target. Build a 320 by 50 storyboard UI with digit and operator buttons.

Trim the keyboard view controller by keeping only override func viewDidLoad with super.viewDidLoad, and remove the next keyboard button and textDidChange function to prepare the app for coding.

Connect the keyboard view controller to Swift code by setting files owner to keyboard controller, then load the keyboard nib as a view and attach it to main keyboard view.

Learn to implement a number pad on a custom iOS keyboard for iPhone, wiring a single IBAction for all number buttons, updating the calculator label, and adding a clear method.

Create delete text action via a UI text document proxy and proxy.deleteBackward, and implement the next keyboard action by advancing to the next input mode; connect actions to outlets.

Implement the four operation buttons (multiplication, division, addition, subtraction) in the custom iOS keyboard and connect them to a single action, using each button’s title to determine the operation.

Learn to build a custom iOS calculator keyboard in Swift by wiring a single calculate action to the equal button, performing add, subtract, multiply, or divide, and updating the display.

Implement a one-time calculation by using a calculate again flag, add a hide keyboard action, and enable the submit button only after a calculated result appears.

Outline how the third keyboard clones the stock iOS 9 keyboard to create a basic keyboard, and preview building the interface in the next video.

Set up an Xcode project and storyboard, place and center a text field, then build a custom keyboard target with a nib interface and loading logic.

Program a custom iOS 9 keyboard in Swift 2 by wiring a key press action to all keypad buttons, inserting characters via a text document proxy, including the space bar.

Implement delete, hide, and next keyboard actions for a custom iOS keyboard, using a text document proxy to delete text, dismiss the keyboard, and switch to the next input mode.

Continue building one more keyboard as you learn iOS 9 keyboards and swift, finish another keyboard, and move to the next section to develop something new.

Develop a quote keyboard that generates a random quote with a middle button and inserts it into the selected text field, using three mandatory keys: hide, delete, and next keyboard.

Create a new Xcode project for quotes custom keyboard, configure a single view app, design a centered text field with constraints, and lay out generate, next, hide, and delete buttons.

Create four IBAction methods for a custom iOS 9 keyboard in Swift 2: hide keyboard, delete text via document proxy, switch to the next keyboard, and generate a random quote.

generate a random Forbes quote by selecting from a predefined quotes array and inserting it when the generate quote button is pressed, using a separate Swift file for the array.

Join this course to learn how to build four real world keyboards in iOS with Swift, and publish keyboards on the App Store.
