Objective-C Tutorial - Lesson 2: Part 2: Programming Basics and Vocabulary

[panchilo83]

A Boolean takes a bit, you idi*t!!! 8 bits = 1 byte... "like super fast app using a char for representing true/false" ???

I made my first iPhone app in about two days. it is for babies ages 0-1. the user touches the buttons with animals on them and the phone plays the sounds of that animal. Baby Farm Animalz on iTunes

[akaalawadhi]

Wow!!!!!!I never thought that learning objective c would be that difficult

[jairojvilla]

Very good tutorials. Thanks so much for the lessons!!

[macrevieweru]

I have downloaded the sdk several months ago and a newer version came out. I was wondering if there was a easy was to upgrade or if I need to delete my current sdk or if when I download the new one if it will overwrite my current. Plz help thanks in advanced.

[TechThoughts]

Using Xcode 4 or Xcode 3?

[macandcomputerhelp]

@TechThoughts I've been using Xcode 3 in all of the lessons so far, but starting in the next one I will be using Xcode 4.

[ilovetodraw555]

how long do you think it would take to learn objective C and build a app? if your really dedicated?

[Freeze00201]

@ilovetodraw555 Depends on what you want to do. The more complex the more knowledge you need.

[GLappDevelopments]

Subscribed after the first video. Thank You soo much. :D

[macandcomputerhelp]

@GLappDevelopments Awesome! Glad to hear that your enjoying them.

[kiduel]

wow! great tutorial, keep teaching! thanx.

[banosFAME]

i like how the number of views wanes as you get further into the tutorial because people give up

[CPA4KA]

Enybody know how to create skinnable interface on XCode for MacOS? Or where can I read about subj?

[kbereznDev]

Good tutorial to start learn Objective-C!!! Thank.

I thing slide about initialization is not quite correct. int anInteger;

Is not an initialization (at least not explicit).

So it is quite interesting if the variable will be initialized by default (with 0, for example) or not. And if the behavior depends on the variable declaration place or not (global, locate, etc).

[neoedwards9828]

Holy crap!!! Amazing tutorial, very clear and easy to understand. I suscribed after watching the second video of this tutorial.

[macandcomputerhelp]

@neoedwards9828 Haha, thanks!

[aselzer]

Yeah, really great video. Thanks for posting

[aselzer]

Yeah, really great video. Thanks for posting

[panadesu]

Why anInterger, and not just aninterger?

[mortl8324]

@panadesu I dunno if you still need to know this but for programming, saying anInteger lets people know its two words. an Integer. As apposed to aninteger which would be read as one word. aninteger. Like iAmGoingToEat lets people know that you are saying i am going to eat.

[panadesu]

@mortl8324 Thanks for the help, much appreciated :)

[itilijen]

This is exactly the types of tut's i've been looking for

Thank you! =D

[zamoray123]

Thansks... in spanish please.... :-)

[kaltsinho]

Are these slides downloadable? Are videos too or we need a youtube downloader to get them. Great work to the creator.

[mepsites]

Thank you very much! I'm switching from Delphi/Pascal to Mac tools and your videos are helping me a lot!

[shadow7guardian7]

THANK YOU FOR BEING ALIVE!

int is not just a whole numbers, because by whole numbers you are only saying that it can be a positive number when int can be a negative number

[TheRoki112358]

@SaviorTOP Do you really know what is a whole number???

[SaviorTOP]

@TheRoki112358 yeah, whole numbers are not negative numbers. Technically in math, they are not positive nor negative, but in terms of programming they are just positive numbers. So yeah i know waht im talking about.

[TheRoki112358]

@SaviorTOP I don't know if I misunderstood you but in mathematics a whole number (Z) can be a positive number or negative number (N). In programming also is in that way, you can define (in C for example)

int x = -20;

int y = 20;

printf(" x = %d, y = %d", x, y);

and it's all ok. As you can see can be positive and negative. I don't know what you mean when you say that "in programming whole number are only positive". Regardless is in math way or programming way a whole number is a whole number.

[TheRoki112358]

@SaviorTOP Maybe the confusion is consider the word "whole" number. I consider that a whole number is an integer number, but in fact it depends on each to define it.

In my country, the literal translation of whole number is integer... this is why I assume that the definition of whole number is clear.

[SaviorTOP]

@TheRoki112358 whole numbers are neither positive nor negative... you can look it up.  They are just numbers that represent a whole. But obviously this is not a big deal since the compiler doesnt care about any of this shit.

[ignas2526]

bool is 1bit 0 or 1.

[ryzhenkov]

Excellent content.

The link to next tutorial is right on the fast forward bar, so I hit that accedentally. please move the link higher, thanks.

[asfadasfa1234]

thanks man!! im still learning regular c which makes this a lot easier, like what i really need is the differeces between the syntax from c to objective c but i understand integers and statements and stuff.

like the differences like NSLog(@"") and printf("")

but im SURE that will be in later videos so thanks in advance

[platnumnutz276]

the bool type is Objective-C is capitalized because C originally never had a bool type so it was added in Objective-C as BOOL and also the values it takes are YES or NO, not true or false. Nice videos, I am learning objective c now and so I read about the BOOL type recently and wanted to point that out, thanks for the video

[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!

[Gandind]

You're off on the integer size by one! Making my own tutorials for C#, just had to point that out.

[MrJonnyrocks]

is it possible for u to send me all ur like power point thingy u use?, then i can study them

[MrJonnyrocks]

thank you sooo much

[RonjaRT]

Good job man. Keep it up!

[joxxen]

thank you for your vids. waiting for the rest =D

[tbvdb]

You're much more clear than any other tutorial I've ever seen or read!

[YouveGotFailTV]

definitely

[jrmovies1234321]

yeah. Seriously thanks a lot for these tutorials!
