We started talking in Article Xcode precious

Xcode

The main tool used to create applications for the iPhone OS is Apple's Xcode IDE (integrated development environment). Can also be used to create a variety of types of projects, including cocoa and profits of the command line.

Launch Xcode (default is in / Developer / Applications) and create A new project by selecting File> New Project. You should see a new window like this:

>> Select Windows-based application.

In the context menu of the product, make sure the iPhone is selected. (Do not select database used for storage. No database used in this example.)

>> Click Select.

A form for you to select your project will be saved.

>> Select an appropriate location for your project (eg the desktop or in a custom directory of projects), project name HelloWorld click Save.

The rest of the tutorial assumes that the name HelloWorld project, so the application is called HelloWorldAppDelegate Delegate class. If the name of your project something else, then delegate the application class is called YourProjectNameAppDelegate.

You should see a new windows project like this:

f you have not used Xcode before, take a moment to explore the application. You should read Xcode Workspace Guide to Understanding the organization of the project window and how to perform basic tasks such as editing and saving files. You can now build and run the application to see what the simulator looks.

> Choose Build> Build and Go (Run) or click Build and Go button in the toolbar.

The iPhone application has run Simulator automatically, and when your application starts, you just see a blank screen. To understand where it came from the standby mode, you need to understand how the application starts.

>> Exit the simulator.

Starting application

The project template that you created and were created on the basis of the application environment. It creates an application server connects to the windows, draw the long bow, and so on. Most of the work done by UIApplicationMain function as shown in below

The main function calls function UIApplicationMain main.m:

int retval = UIApplicationMain (argc, argv, nil, nil);

This creates an instance of UIApplication. It also analyzes the Info.plist property list of the application. The Info.plist file is a dictionary containing information about the application, as the name and icon. May contain the name of the pen must be under load, indicated by the key NSMainNibFile. files contain records of tip elements user interface and other objects, you will learn more about them later in the tutorial. In the Info.plist of your project, you should see:

<key> <NSMainNibFile / key>

> <string> MainWindow </ string

This means that when the application starts, the file is loaded MainWindow tip.

>> To view nib file, double-click the group MainWindow.xib Resources the Project window (the file extension "XIB", but by convention is designated as a pen case. ") Interface Builder launches and opens the file.
