[Freeze00201]

@iH4ckuriDevice Foundation is Objective C so for this tutorial use FOUNDATION. :)

[superelephant360]

When I click run and then console, the window that pops up in empty, and on the bottom left it says 'Build Failed (1 error)' and on the bottom right it has an icon with a hammer, then it says 'Failed' then there's a stop sign with an exclamation mark, and then the number 1. Does that mean I typed something wrong? Because I checked it by comparing it to what you typed and I don't think I did.

[ilovetodraw555]

HELLO WORLD

[forumpaul]

when i click build and run i get some errors:

expected expression before '@' token

character constant too long for its type

format not a string literal and no format arguments

[chrislane535]

HOMEWORK!!!!!!!!

[flouki1]

Great Great video, i hope the rest of the series is as good! when u read a book it doesn't go step by step for absolute beginners and all of a sudden you find yourself totally lost!

[nickandstu1]

How do you format the string if the output will be a negative integer?

[TheAviatorMan]

Quick question, when you save the program, do you tick or untick the 'git' option? thanks

[gagginaspinnata]

audio is too low

[GraphicalMadnessGFX]

xcode only works on mac computers.... like so everyone sees

[ronniexyz]

In create new project , i don't get the System (where it says to select foundation) after hitting the application and selecting the Command Line Tool. What i'm missing. I have downloaded the XCode 4 after paying $4.99.

[vasu2021]

nice tutorial

[rockandrolljackable]

Really excellent tutorial!

[mortl8324]

must you use nslog? like for java you just put System.out.println("blah blah blah");

[asphyxiateDrake00]

Right once you said, "If this is truly going to be your first program, we gotta add something" I could tell hello world was coming. Hahaha

[zamoray123]

Thanks....... in Spanish Please...... :-)

[TheChrisR12]

With NSLog whats the @ for?

[Zombiebrainstew]

Dude you're awesome peace

[gerwin136]

i typed it exactly like you, but i get an error at every NSLog line... please help

[macandcomputerhelp]

@gerwin136 Make sure when you create your program that you choose Foundation for the type. I have an annotation up, so make sure you have those turned on and re-watch the video.

[gerwin136]

@macandcomputerhelp ah thx it helped :P

[kong023]

@macandcomputerhelp what is the @ in front of the string is for

[ilovetodraw555]

@gerwin136 SAME HERE

[hellicare08]

hello, can i know what are the areas of application of objective-c?

[djfong]

Hey, you sound a lot younger than me but I just wanted to say that your lessons are great! I've learned a lot so far and really appreciate your patient and thorough step - by - step explanations. Thanks again. I want to make an ipad app so this is a great start i'm sure - Adrian

[greedygoohgle]

So if I understand this right, you can put a placehoder inside the displayed data. That would be the %i which is the placeholder for e.g. "a" which is perviously definded as "1" and previous to that definded as an integer and declared to reserve memory.

[youngestpilotinGa]

i downloaded X-code and its got a lot more items on the list than yours it doesent let me select foundation theres allot of cocoa and C++ stuff help?

[marsunderscorefenix]

lol! i remember doing my first c++ hello world xD!!!

[sobeservices2UK]

Ok good video only one problem. When you tell someone to open up xcode.

Make sure you have them select foundation.

You tell people to open up Command Line under Mac Application

But make sure the Foundation is selected as well other wise you are opening up your project in C or C++ and I found I had issues with the examples running when I did this.

[macandcomputerhelp]

@sobeservices2UK Um, I have an annotation that tells you that.

[webzcom]

@sobeservices2UK - Same problem with other tutorials too... Seems to be a common step that people leave out. Drives newbees nuts.. Got me. :-)

[marinamarinova123]

@sobeservices2UK

How do you select foundation? I have problems running the examples - an error on every line and also the interface of my xcode is a little different then the one one the video

[99tpen]

Wow!!! this is really helpful. I tried reading a book on this but its wayyyyyy too dull and hard to follow. These vids really help you get a feel for the language! Thanks for the videos man, theyre great!

[gblax123]

This pretty much helped me better than the 6+ hours of iTunes videos I watched from the Developers.... thank you

[Midgar777]

So I'm gussing NSLog is the equivalent of actionscripts trace function?

The bit that confused me is that in flash its trace("hello "+a) which would give hello 1 based on your video.... but in Obj-C The NSLog() bit makes sense but I don't get what the other parts inside are there for.

I've ordered some book though and I'll keep workingthrough your vids, cheers man :)

[jjohnston2]

what if i have a pc.........?

[macandcomputerhelp]

@jjohnston2 Well some other people have said that there are Objective-C compilers for PC's, but Apple's Xcode and development tools are only available for Macs.

[izne]

@jjohnston2

if you have a pc, then you buy a mac and start your real life ;)

[hamadminmgr]

I copied exactly what is written in your video and it did not work. It says expected expression before '@' token. What does this mean?

[macandcomputerhelp]

@hamadminmgr Make sure the type when you create the project is Foundation.

[happyspazzy]

Great tutorials, this has helped me so much. I have been looking for a video like this

[darkmochaz]

Wow bro! These tutorials are awesome!!! Your videos have helped me so much in understanding the basics of Obj - c. Most tutorials on the web left me scratching my head, but your instruction have really hit the nail on the head for me! A++, keep'em coming, these videos are great.

[MRRSENA]

Thankyou,, giving such a nice tutorial..

[tallswede68]

What is nslog? I keep getting errors, "syntax error before @ token"

[ashnabwa7d]

@tallswede68 same problem .. any clue ?

[macandcomputerhelp]

@ashnabwa7d Make sure the type when you create the project is Foundation.

[macandcomputerhelp]

@tallswede68 Make sure the type when you create the project is Foundation.

[macandcomputerhelp]

@tallswede68 Make sure when you create the program that the type is Foundation

[4gamerslikeu]

AMAZING VIDEOS!!! Please don't quit, this is really helpful for anyone that wants to learn programing. I've been searching for a good video and this is it THE BEST CHANNEL TO LEAR OBJECTIVE C and more! Thank you so much!

You have a lot of patience and that helps a lot to understand the lessons.

THANK YOU!

[synergy989]

Just finished this video and have to say you are doing a sound job. Just want to make sure I understand: in the String the @"Insert text" is not executing anything right? All the string does is display what you type? What about multiple %i? Example (@" a + b = %i or b + a = %i", c, d); would that be correct? (Assuming we declared d)

[macandcomputerhelp]

@synergy989 Yes, that would be correct.

[Mr100jko]

very nice !!

[abufaisalplus]

Outstaining

[Plan3SkIPP3R]

@abufaisalplus Oh yes, outstaining!

[cmhaggerty77]

I don't have the snow leopard, and I am using the XCode for leopard, I can't find the command line tool, which would you suggest?

[JustinMPerea]

I was going this and it didnt look at the same

i ddint have .m

[MadeOnAMac365]

@JustinMPerea After you press "Create a new Xcode project" and "Command Line Tool", click the Type bar and make it "Foundation". I had this problem, too.

[JustinMPerea]

@MadeOnAMac365 oh cool thank you

[monalichi]

Keep up the good work, man. This is the first quality Obj-C tutorial I've seen that gently but effectively introduces not only Obj-C, but general programming fundamentals.

[tbvdb]

Jup, it's really great !!

way better than iTunes U :P

I've never programmed before, and I understand all of this now!
