Some nice beginner tutorials here.

First, this is a very simple demo but take from it what you will. This isn’t meant to be a tutorial as much as a reference guide. So if you don’t know how to do one of the steps there are MANY tutorials that will guide you through the set up process.

First thing to do is start an Xcode project and set it to a basic view based application.

Open the view controller and add an IBoutlet called “label”. Add the associated @property and @synthesize commands and then open up the viewController.xib file. In the .xib file add a label to the view, link that label with the IBOutlet we made earlier.

Now: Add a new file to the project, and instead of selecting the iphone stuff, select the mac osx stuff under it. In that select “C and C++” then add a C++ file, call it “Math”.

Define a very simple class:

class Math {

private:

public:

int addNumbers(int num1, int num2);

};

Then in the .cpp file add this:

#include “Math.h”

int Math::addNumbers(int num1, int num2){

int total = 0;

total = num1 + num2;

return total;

}

If you can’t figure out by now we are making a class that adds two numbers.

Now import the math class into your .h file of the view controller, and then in the implementation add this to the “view did load” function

- (void)viewDidLoad {

Math tempMath;

int tempNum = tempMath.addNumbers(1, 1);

NSString *tempString = [[NSString alloc] initWithFormat:@”%i”,  tempNum];

label.text = tempString;

[tempString release];

[super viewDidLoad];

}

Lastly but not least change all your .m files to .mm files. This tells the xcode compiler to compile the code as both objective C and C++

If all goes right, you will see 2 as the label, and this information was called from a c++ class. I have also attached the project file for reference.

You can find it here.

As of this post there are 10 tutorials, and they go through the process of creating an iPhone game with the OpenGL:ES framework. While it is all fun and good to use Cocos2d and so simple, there are fundamental aspects of that engine that people should understand before using it.

That little icon on the far right side is a SSB I created that links to the reference page for the cocoa2d game engine. So rather than open a new browser and go to the page I can just click that icon and there is the documentation. Like so:

The other app I have started to use today is called “GeekTool” It allows you to run the display of any unix shell command on your desktop. This includes everything from the time, to any script you write… Anything. It also has features for the system log, and a picture from the web. Frances Comugnai has a really cool post on his site about what you can do with it. A def must.

The guys over at iphone incubator have a post up about changing the name under your iphone app.
