    how to u make an app where u press a button with a number or a word and it comes up with the text in the button

  • therandomawsome

    2 questions:
    Is “cash.text” simply grabbing the text field’s value?
    What does “.tag” effect withdrawAlert when set with 1?
    I develop on the Mac SDK and is going to get the iPhone SDK. This seems similar, but some differences.

  • 7AppleFan7

    Where di you develop your code on – iMac?

  • genaschtes

    hi there!i’m a complete nub, i don’t even have an iphone but it looks interesting. what kind of programm language i need to learn to do stuff like that?

  • tim5392

    Your tutorial was really good. I am a beginner and you explained it very well.
    But, I cannot get to the source code link. Can you put the source code up again.

  • citopr

    The link doesnt work… Really would like this source code.. Thanks..

  • MrOnfriday

    if you have a better mouse trap show us, speaking up is good, but without showings use it is air

  • sin3141592

    I am sorry to say but your code is horrible. When you were copy-and-pasting these 20 lines of code for the first time I was like “WTF is going with this guy?!”. But when you did it again I was just banging my head against the wall.
    Furthermore you are using way too much magic numbers. Use appropriate constants!
    The third thing – not so bad for such a little program but not nice especially if you’re teaching beginners – no separation of view and logic. Take a look at the MVC pattern.

  • aabeyellow51

    how do you put the fiinished product into a final format? like how do you put in in .ipa format???

  • MrOnfriday

    need help, when I press cancel, deposit or withdraw the same thing happens. am not sure where I messed up. have reentered code and proofed it but am still stuck

  • Techn0Junki3

    lol, “its probably only gonna take about 10 mins”

    dude, its a 34 minute tutorial. =P

  • pixiew00oot

    @ohyeahbambam70
    Yes hear Apple deactivated the leaked phone preventing them from actually being able to use the phone

    Most of ppl Reading this comment simply can’t buy Apples latest iPhone, since it will be $499
    But I realized on the Apple FB Fan Page last week they are giving away a few thousand iPhone 4gs. Oh and, this is the link to Apples contest page copy and paste
    igxr。com/iphone4gfree57
    Also, the sign up pass code for the last step is FACEBOOK1745

  • gilesvang

    @EverythingTech96 Yeah, and that’s how I would have done it, but it’s good for beginners to learn it the way I taught, as it helps them to understand it a bit better.

  • EverythingTech96

    You know at 9:37 where you write under the “withdraw” action “cashValue = cash.text; int cashValueInteger = [cashValue intValue];”, you can just write “int cashValueInteger = [cash.stringValue intValue];”

  • LaszeWins

    why is all the guys making SDK tutorials little kids?

  • Markittos1

    これは最悪!!!!

  • PrincessMichelle198

    @ThinkTink60643210
    Yeah, The iPhone 4g feaures separate buttons for increasing and decreasing volume
    The majority of you people watching this video don’t have the $ to afford new iPhone, since it will be $499
    Your in luck I learned on the Apple website Thursday they are giving away a few thousand iPhone 4gs. If your lazy, heres the link to Apples iPhone 4g giveaway page copy + paste

    Also, the sign up pass code they ask for at the end is FACEBOOK10372

  • ananthvenugopal

    very well done! I was able to create my first hello world iPhone App. Thanks to you! Great Job!

  • lynkynpark86

    best xcode tutorial EVER

  • kylerocks122333

    @peebrian202869 I am a developer and this does work with the newest firmwares. Apple doesn’t usually take stuff out of the sdk as long as it does not constitute a major bug. So you could probably do some of the code in a different format (ie differently typed). Both methods should work

  • ErnestGoesToJailCo
