Xcode 4 iPhone SDK Tutorial - Create a Calculator PART1 (beginners) HD

[LifeMattersChannel]

no sound?

[ginton]

Word, your calc app looks super easy, i tried one from the stanford university site and that looks far more complicated than what you have done. Thanx m8

[HegfZero]

CalculateViewController.xib has been replaced with StoryBoard! It works the same way!

[HegfZero]

@HegfZero calcuateviewcontroller.xib = Storyboard

[mrswimtim]

i cant find the calcuateviewcontroller.xib

[snowflakesandstars]

No sound = No good

@recobafan Have you connected the buttons and the textfield with the files ower?

[recobafan]

I think I have the right codes (they are the same as the codes you have on your link) but when i have the calculator on my ios simulator, I can type in numbers to both TxT fields, but 'calculate' and 'clear' do nothing.. Thanks for any help!

[CitydriftSL]

Dein Rechner ist Echt gut :)

Weißt du vielleicht wie man eine if- abfrage einbaut das man auch addieren subtrahieren und so weiter kann?

Danke :)

[Mapple2011]

@CitydriftSL Probier das mal aus ; ) : /file/rwp6bz Ich habs dir auf sendspace hochgelanden

[CitydriftSL]

@Mapple2011 Danke :)

[Mapple2011]

@CitydriftSL ein part 2 kommt bald ; )

Having the same problem as @Il2Flyer , I have the latest Xcode version. While running the first build test on "ViewController.m" right after the clear function the following code:

>> - (void)dealloc

{ [super dealloc];

}

<< gives me the error "ARC forbids explicit message send of dealloc'" on the line of "[super dealloc];".

I have little to none coding knowledge, could you post a fix for this? Thanks! ^_^

P.S. I tried to give you as much information on the error as I could.

[JonsAdventureStories]

@Mapple2011 I can't seem to find the '.xib' file in the latest version of Xcode. Could you please tell me where it can be found? Thank you in advance.

[rip111buddy]

@JonsAdventureStories the new Xcode (4.2.1) has STORYBOARD mode......to remove that while creating a new Xcode ios app based project , just uncheck the Storyboard

and VIOLLA

YOU WILL HAVE

iPhone xib

and

iPad xib

This vedios making us to learn programming very fast !!!

[Il2Flyer]

HELP!!! I got a error like this: - (void)dealloc

{ [super dealloc]; ARC forbids explicit message send of "dealloc"

}

[UgotHacked35000vr]

Its a good tutorial i just tried it, everything works fine, exact its not multiplication apparently is "to the power of"

[BeastofRage]

thank you so much, I finally get XCode4 right now. YOUR AMAZING :D

[PeopleOnCamera]

wtf is before the 2 in @"2.f" ?????????????

[zhazhago]

no way to hide keyboard after key in

[Mapple2011]

@zhazhago you have to change the keyboard-type if you want to hide the keys ;)

[zhazhago]

@Mapple2011 can be more specific?

[lilkev3976]

This doesn't seem to be in Xcode 4 either!!!

[Mapple2011]

@lilkev3976 What do you mean?

[lilkev3976]

I'm about to try this to see how it works, but honestly the worst thing you can do is a tutorial for beginners that doesn't work 100%. Yes it is good to let people struggle a bit but if your cause too much frustration it will further hinder the learning process!

[balcerman]

Thanks for this tutorial, very useful for me as a Mac newbie :)

[ThePachaaa]

mi english is bad but you have an error there..

float c = x*([textfiel2.text floatvalue]); // this is the correct way.. haha you put a 1

bye

[Mapple2011]

@ThePachaaa Yes sry. I´ve correct this

[narutoanime133]

EDIT: I changed float c = x*([textField1.text floatValue]); to textField2, and it ended up working just fine~

You might want to fix that in your video ^^;

[Mapple2011]

@narutoanime133 Yes sry. I´ve correct this

[narutoanime133]

I just tried this, but i noticed something a bit off.

The calculator is only multiplying textField1 by itself, it isn't multiplying by the 2nd number. My calculator was doing this when I tried, so I used the computer's calculator to try your 2nd multiplication, and it did the same thing.

The answer to your 2nd one is 474,198,375,757,964, not 300,901,423,028,109,312

[Mapple2011]

@narutoanime133 Yes sry. I´ve correct this

[narutoanime133]

@Mapple2011 Haha, no problem! It's a simple mistake :P, but I'm surprised no one else has found out about it

[Mapple2011]

@narutoanime133 There are three other people -.-

[iSmashUriDevice]

thx soo much so how do you put on ipodtouch???

[Mapple2011]

@iSmashUriDevice Thats a simulator :)

[iSmashUriDevice]

@Mapple2011 i know lol :) see my vid of this :)

[Mapple2011]

@iSmashUriDevice When you want to put this on an iOS Device you have to pay 99$ for the Developer Certificat or you have to jailbreak your iDevice and modify Xcode, but don´t ask me how to do that :)

[iSmashUriDevice]

@Mapple2011 lol i know that but im jail-broken im searching how to do that don't worry i wan't crowd ur comments with questions all i ask is if you could sub me :D lol

[Bredli37]

Thank you. Works like a charm :)

[Mapple2011]

@Bredli37 Thx :)

[iwantapigtoday]

where did u learn to do this

[Mapple2011]

@iwantapigtoday

At first I watched tutorials, too. Then I've looked at forums about Xcode developing. Then I began to develop own simple apps. etc........... :)

[geoffgmartin]

very helpful! Thanks!

Even the textField1 bug was helpful as an intro to debugging...

[rafee54]

hi mate, thanks for that bur could you do one that you can choose the different sum so + - X and / please

[MacintoshOSXI]

Automatic Reference Counting forbids explicit message send of 'dealloc'

please help!

[BnBsDailyLife]

nothing happens when i click on the .xmb =/ im kinda stuck at the moment, can someone possibly help me??

[Mapple2011]

@BnBsDailyLife Maybe try to do a double click or a single click on the .xib file. When you have a old mac, you have to wait a little.

[ayaloureiro]

why in my project the placeholders not shows :(

[Mapple2011]

@ayaloureiro

which placeholders?

[Mapple2011]

Thank you! :)

[Mapple2011]

@xH4CK3Rx66 Yes, but I´m working to fix it. Maybe I do a new calculator tutorial :)

[xH4CK3Rx66]

REALLY SATISFIED!!! GREAT VIDEO!! but, when i click the clear button, the answer that i want to clear, doesnt go away.. :( great video!!

[Mapple2011]

@xH4CK3Rx66 Thx!

Did you have connected the "label" Outlet via File´s owner to the "invisible label" under the text field?

Please see 5:40min. - 5:56min. and 7:32min. - 7:39min. :)

[HenrikTheFilmMaker]
