06:42

Learn how to setup your Mac with Xcode 5.

17:41

Learn how to setup up a PC with MacInCloud.com so you can start today.

24:24

Create your first iPhone app and run it on the simulator.

Here you will see how yo make a simple calculator app for iOS. Create a new project in Xcode, design a simple UI and make it work.

Follow along to build a working app that with do the math for us when brewing Artisan Coffee.

P.S. Interested in Artisan Coffee brewing? See my blog post.

07:43

We all run into bugs when coding, especially when we are learning new techniques. Here you will learn the basics of debugging.

Turn on line numbers in Xcode, see some common bugs, and learn how to squash them with Xcode’s recommendations.

Learn how to rename variables, fix broken connections to your UI, comment out lines of code, and read the debugger output.

Section 2: Variables and Types
10:21

Variables are how we store information in our apps. We use them to ask the computer to remember a date, or a number, or other information. In code, we give this data a name so we can remember it too.

Learn about the common kinds of data or types, how to create them with names or aliases, and assign an expression to this variable.

Some basic types:

  • short/int/long: -1,0,1
  • float/double: 3.14
  • char: ‘a’, ‘b’, ‘c’
  • pointers: int *(store addresses)
  • struct: (x,y)
09:23

Jump into Xcode and make simple mac to learn how variables work in code.

See how to use NSLog to print out your variable as a means to checking its value. This practice will become very useful to test your apps behavior as you develop.

Create the common variable types (ints, floats, etc), perform operations on them, and see how they behave.

06:46
Section 3: Decision Making
07:36

We need to teach our apps how to make choices. If it is rainy out, we need to bring an umbrella.

This lecture will go over logical decision making. We will cover if, else and else if statements so we can make these logic based decisions. Learn the syntax needed to implement the choices your app will need.

We will cover a new type called BOOL, boolean operators like less than or equal to, and the logical operators AND, OR, and NOT.

18:54

Create an iPhone app on the storyboard to see how decision making works in practice. design a user interface with labels and buttons. Change label text in your app when your defined conditions are met.

Practice making working iPhone apps in Xcode. Follow along to practice making and modifying variables, implementing if statements, and working with the BOOL type and logical operators.

Learning how to implement decisions is a crucial part of app development. This video will show you how to work with decision making in iPhone Apps.

Section 4: Functions
07:40

Functions are the building blocks for how we get our apps to behave how we want them to. You can think of functions like the directions that come with IKEA furniture. They show you how to take all of the parts and put them together in order to build you piece of furniture.

If you had another set of the parts, you could use them again and again. Functions are the same way in that we can use the same code many times without have to rewrite it.

Learn about how functions can save you lines of code, and how their implementation works in memory with the stack frame.

Xcode - Functions
08:16
Section 5: Advanced Functions
05:22

Learn more about how functions work. We'll also learn more about the Xcode debugger for stepping line by line through code.

Xcode - Advanced Functions
11:21
Xcode - Global Variables
14:49
Section 6: Numbers
11:01

Numbers are a fundamental building block of apps. We will use them to store user data, control the components in our apps, and perform calculations.

Here we introduce the types of integers and floating-point numbers we will commonly use. We cover how they work with the NSLog function, and how we can gain access to the built in math libraries so you don’t have to write code for basic functions like sine, cosine, etc.

Common Versions of Integers:

  • char
  • short
  • int
  • long
  • long long

Common Versions of Floating-point Numbers:

  • float
  • double
20:19

Numbers are a fundamental building block of apps. We will use them to store user data, control the components in our apps, and perform calculations.

Follow along to work with the common types of numbers and see how your apps will handle them. See how overflow errors can cause strange behavior, a good reason to choose the proper number type. We will also go over the orders of operation so you know where to put your parenthesis in your calculations.

Additionally we will cover the math libraries and special operators such as the increment and decrement operators that will save you lines of code.

Section 7: Loops
09:52

Loops allow us to repeat actions multiple times. We use loops in when downloading an album of pictures from the web, when we are editing photos, or even when you are making a game and checking if a player has won yet.

Here we cover the structure of basic loops, the while and for loops. We also go into the functionality of the keywords break and continue that end the loop early or skip a particular iteration, respectively. This background will show you how to create the behavior you are looking for in a loop.

13:31

Loops allow us to repeat actions multiple times. We use loops in when downloading an album of pictures from the web, when we are editing photos, or even when you are making a game and checking if a player has won yet.

Follow along as we use a loop to reproduce the behavior we had in the countdown clock without having to use the recursive function call. Next we cover the for loop and use the debugger to see exactly what the computer is doing as it runs through our code. Lastly we add a continue call to the code so we can see its behavior with the debugger.

Section 8: Pointers
14:40

Pointers are a special variable type that allow us to store the memory address of another variable. This gives us access to the location of our variables while not having to hold on to them all at once, akin to having the catalog for a library instead of carrying around all of the books.

In this lecture, we introduce memory and how your computer handles it. We use this context to show how we can use pointers to store the location of variables and how we can use that to retrieve and modify them. Lastly we introduce the NULL pointer and its uses.

11:46

Pointers are a special variable type that allow us to store the memory address of another variable. This gives us access to the location of our variables while not having to hold on to them all at once. Follow along to practice creating pointers, dereferencing pointers, modifying variables via pointers, using the NULL pointer, and using the sizeof function.

Section 9: Pass By Reference
06:06

Pass by reference allows us to give a function or method the address (via a pointer) to the data we want to operate on. This is especially important when dealing with large data sets like images or videos. You don’t want to have to copy an entire movie just to play it, rather, it would save time and memory to play it from its current location. Pass by reference allows us to do this.

Additionally, pass by reference allows us to modify variables within a new stack frame such as in a function or method without having to use global variables. This leads to more robustness and reusable code.

13:08

Pass by reference allows us to give a function or method the address (via a pointer) to the data we want to operate on. This is especially important when dealing with large data sets like images or videos. Follow along to see examples of Pass by Reference and pass by value.

Section 10: Structures
02:57

Structures are a way to easily organize data. Instead of having separate entries for the same person, have a single contact with all the information for home number, mobile number, addresses, etc.

Xcode - Structures
04:55
Section 11: The Heap
07:50

Managing memory is especially important on mobile devices. Learn about how applications can create a buffer of data to speed up user access. This is what YouTube does when it downloads part of a video so you can start watching right away.

Xcode - The Heap
12:27
Section 12: Objects
10:47

Objects are a way to easily organize data and functions for reusability. Instead of building functions to turn a car in a game, build a car class that comes with them anytime you make a car.

Xcode - Objects
12:51
Lecture - Object id and nil
04:38
Section 13: NSString
05:24

NSString is a class that you will use often in your apps. Learn how to make new strings and utilize the given class methods.

Xcode - NSString and Common Mistakes
14:12
Section 14: NSArray
05:06

Your apps will have to deal with lists. Lists of enemies in your game, lists of dates, or lists of other data. Learn about the NSArray class to manage them.

Xcode - NSArray
15:45
Section 15: Documentation
16:12

Apple's documentation is your best friend when you are trying to implement something new. See how to go about looking up documentation.

Section 16: Custom Objects
08:05

Your apps will have custom components. Learn how to make your own objects so you can reuse them and write less code.

Xcode - Custom Objects
14:24
Section 17: Properties
07:28

Properties help you write less code. Take advantage of them to speed up app production and to write fewer bugs.

Xcode - Properties
09:33
Section 18: Class Inheritance
10:51

Learn how your subclasses take on the properties of their super classes. A convertible car is a car, so it can drive, turn, etc., but it also can open its top. Subclass car so all you have to write is the code to open its top.

Xcode - Class Inheritance
16:19
Xcode - Troubleshooting Class Inheritance
07:26
Section 19: Object Ownership
10:23

Apple's Automatic Reference Counting (ARC) saves you a ton of coding and avoids bug. We need to know how objects we create will be treated. Learn how object ownership works with ARC.

Xcode - Object Ownership Part 1
10:19
Xcode - Object Ownership Part 2
21:04
Xcode - Object Ownership Part 3
16:09
Section 20: Memory Leaks
04:58

When object ownership is not handled properly you will have memory leaks. Learn how to diagnose memory leaks to make fast apps that don't crash.

Xcode - Memory Leaks
10:05
Section 21: Properties Modifiers
11:57

Learn about the different ways to modify your properties and what that does to their behavior in your apps.

Xcode - Properties Modifiers
15:34
Section 22: Course Review

Lecture - Paper Prototyping
15:26
Section 24: Connecting UI Outlets and Actions
12:17

Here we start to connect the elements of our user interface to code so that the users actions can translate to the responses we design.

Section 25: App Logic for MatBorder Class
09:56

We implement the main functionality of our app in a separate, reusable class.

Section 26: Connecting App Logic to UI
08:54

Now that we have the functionality working, we need our app to utilize it when the user interacts with our UI.

Section 27: Keyboard and Delegate Objects
14:02

Often we use the keyboard for user input. We need to teach our app to hide it when the user is done. Here we also cover how to get special keys like the return key to work.

Xcode - Keyboard and Delegate Objects
16:14
