Integers problem

Question

Hello, I'm new to object C and I need some help with two things:
1. I'm trying to create a counter in a ibaction method that when its clicked the value of a uilabel
changes...IE 1 2 3 4 5.
2. I'm also trying to pass that value into a global variable so that I can access it in another function.
Here is what I have so far.
-(IBAction)clicking:(id)sender
static int count;
count++
myLabel.text = [NSString stringWithFormat:@"%d\n", count];
The label updates but I cant assign the value of count to a variable. I want the data of count to be stored so that I can add it to anorther integer.
please help, getting real frustrated.

Answer 1

[self otherFunction] is the correct and most common way to call an Obj-C function. But in Obj-C, it's more correct to say we're "passing a message" to self, instead of calling a member function of self. A function that's a member of an Obj-C class is called a "method" and its name is a "selector" that the class responds to.
Of course the software does the same thing no matter what you call it, so don't worry about any of that right now. I was just showing off the new words I learned, since Obj-C is new for me too.
Btw, it's also good to remember what Tod wrote about formatting code in this forum (since we hope you'll come back!). Notice how Tod's code is indented correctly, and appears almost the same as in the Xcode editor? Notice how none of his square brackets are missing? The code you post could look that good too!! All you need to remember is this:
paste your code here
If you're not sure you did that correctly, just click on the Preview tab before you Post your message.
The other night I had a dream that Tod bumped my code formatting thread up in the Feedback forum. It was very real, but turned out to be just a dream.
As to books, a lot depends on whether and how much you've programmed before. If you know a little of the C language, you can start learning Cocoa right away because you'll pick up the Obj-C you need as you go along. If C is new to you, it might be good to get a book on C, then a book on Obj-C. But you can continue to build iPhone projects while you're studying the language. In other words, get the language books you need, but don't feel you have to get to the back cover before you can have fun building projects.
That said, if you want to develop iPhone apps here's the book to get right away: +Beginning iPhone Development:+ Exploring the iPhone SDK by Mark and LaMarche. The projects are so well explained and tuned to what you want to know, you'll think you're an iPhone programmer by the time you're into Chapter 6. Actually, by the time you finish Chapter 9 you'll be able to answer several questions a week in this forum.
Of course the other resource you never want to be far away from is the iPhone Dev Center online library. Read the docs you can understand and don't worry about the rest for now (except in a few months you'll be glad you remembered where some of those docs live). Some of the tutorials are really good, but very few of the docs are intended for beginners (or if they are, the authors forgot what beginners need to know first). So just explore what's there and start bookmarking the pages you understand. Not to worry, because 80% of what you need to know in your first year will be explained in Mark and LaMarche.
