How To Make an App – Ep 8 – Swift Subclassing and UIKit

[ad_1]
How To Make iPhone Apps with NO Programming Experience!
Lesson 8: Swift Subclassing and UIKit
This lesson covers more Swift programming language concepts that we need to know (subclasses and uikit) before we dive back into our Xcode project!

This video series uses the latest and greatest from Apple (Xcode 6, Swift, iOS 8) and will teach a beginner with no programming experience how to make iPhone apps. I’m creating these videos with the assumption that the student has no prior knowledge and is starting from scratch.

The lesson plan for the How To Make an App series can be found on my site here:

    Note that "println" is not used anymore in latest Swift. Instead use "print" or : print("my text n").
    Also see there : http://stackoverflow.com/questions/24072775/difference-between-println-and-print-in-swift

    Instead of overriding walk why can't you just make a new funcion

    Chris, please help me since my derelict co-worker won't help me…

    Some codes are not working on my end.. e.g.

    I type:

    println("I'm walking") and instead of it printing on the side "I'm walking" like it does for you, nothing happens for me.

    I type:

    var a = Person()
    a.Name "Alice"
    a.Walk()

    And again nothing prints/appears as it does for you

    I don't understand what I'm doing wrong…

    I'd love your help.

    Thank you!

    What do you do when you go to override but it says 'method does not override any method from it's superclass'

    you said you have to have init in your class, why is that? and if you don't need it can you just leave in empty? and another question, on the site it said UIkit.framework what does framework stand for? Thanks

    I'm having some trouble with the SubClass SuperHuman. It doesn't seem to inherit the properties of Person. Error Msg is 'Superhuman cannot be constructed because it has no accessible initializers.

    I laughed harder than I should have when he decided to make the function "Fly" and make it print "I'm Flying"

  21. 조용준 Avatar

    What`s "init"? What about subtract "init" the first code?

    Chris, thanks, you're making things I've been trying to learn elsewhere start to fall together to make sense.  Nicely done.

    Hi Chris.
    Great teaching, great voice great video/slides production.
    I have been frustrated trying to learn a few things since i have
    absolutely no experience with programming. Your style is friendly
    and very inclusive to even the smallest details.
    Thank you so much and no doubt i will buy your lessons.
    This is really GENIUS.

    Cant wait to keep learning more!

    chris  I want to say that you are amazing.  This video made a lot of sense.  I will watch it over again just to make sure I got it down packed.  Thank you.

    Hi Chris,
         How would i go about getting the numbers on the left side of the screen to appear, it would make following along much much easier. thanks, videos are great and helpful keep up the good work.
