iPhone App Programming for iOS7 – Create a real iOS app

Learn the essentials of Xcode and Interface Builder, connect UI to code with outlets and actions, and build a days-to-weeks calculator running in the iPhone simulator.

Learn to build a real iOS app with Xcode, using interface builder to connect outlets and actions for a days-to-weeks converter in Objective-C.

Learn Xcode 101 troubleshooting to fix interface builder connections, undefined key exceptions, and crashes by reconnecting outlets, inspecting the console, and correcting mismatched braces and parameters.

Learn core iPhone app development terms and concepts in Xcode and Objective-C, including iOS, Interface Builder, methods, objects, APIs, and common keywords.

Choose a passion-driven app idea and sketch its workflow on paper to clarify goals. Build a framing calculator app with live preview and gesture-based controls that auto compute mat dimensions.

Design a simple stopwatch in a single-view iOS app using Xcode. Build the UI with start, stop, and reset buttons, a top label, and customizable styling.

Learn to build a real iPhone app UI for a map and border calculator, designing a two-panel interface with labels, text fields, and images in Xcode.

Build a stopwatch app by configuring an NSTimer in a view controller, learning instance variables, a scheduled timer with a selector, and stopping the timer with invalidate.

Connect the user interface to code by creating outlets for text fields and labels, wiring the calculate button action, and print text field values using tokens.

Connect the start, stop, and reset buttons to code with IB outlets and actions, format dates with a date formatter, and ensure a timer runs by guarding the timer pointer.

Create an Objective-C class to store map board data, including frame and image dimensions and border values, and implement a calculate borders method to compute horizontal and vertical borders.

Build a stopwatch by calculating elapsed time between start and stop dates, updating the display every 0.01 seconds, and formatting hours, minutes, and seconds with the gregorian calendar.

Add millisecond display and resume functionality to the stopwatch, calculate elapsed time using time intervals, and fix layout and formatting issues for a polished iPhone app.

Fix a stop watch bug to ensure elapsed time resumes from where left off by adjusting start date and stop date logic, timer creation, and breakpoint debugging.

Refactor a stopwatch to compute elapsed time using Unix time and UTC, adjust with time zone, and introduce a reusable helper that formats time intervals.

Link the app logic and the UI by creating and invoking a calculate method that reads input from text fields, updates a map border object, and refreshes labels.

Create a stopwatch custom class to encapsulate timer logic separate from the view controller, exposing start timer, stop timer, and reset timer, enabling multiple timers and future delegates.

learn to hide the keyboard by resigning the first responder and end editing, and implement ui textfield delegates to handle the return key and manage delegates safely.

Learn to create a custom stopwatch delegate protocol and conforming objects to enable inter-file communication, implement required methods, set delegates, and build flexible timer logic with a customizable display format.

Learn how auto layout in Xcode manages interface elements with constraints, leading and trailing edges, widths and heights, and dynamic content to adapt to portrait and landscape.

Explore how auto layout uses constraints to position UI elements on iPhone screens. Learn about multipliers, constants, frames, and how Xcode signals good or conflicting constraints.

Learn to use auto layout in Xcode 5 to position views with constraints, set width and height, and preview layouts across form factors with live preview and the assistant editor.

Master setting up auto layout constraints from scratch, pin views with leading and top edges, define width and height, and center content using intrinsic size and size to fit.

Learn to build and align interfaces with auto layout constraints, center content, and use live preview to adapt to different screen sizes.
