icons to applications starting with XCode generated

If we were to assign a nice icon in our program created with XCode , but we did not have a picture. Icns , the format used by Apple for icons, we must not despair, look for a program that carries out the conversion. This program comes with Apple's Tool the DVD to install the operating system or freely downloadable from the Apple website. The program is called Icon Composer and we can find inside the folder Developer / Applications / Utilities . Once opened , just sempicemente move over the image to be processed, which will create icons in different sizes atumatico, doc.number menu "File" "Export" and GOCO's it.
To add it to your XCode project, move the file. Icns just created in the root folder of the project, open XCode, premre twice on the active target for compiling, check the item "Icon File" and enter the file name. Icns . XCode will seek to create within the file. App generated Resurce a folder with the image and the file. App selazionata will be represented by the icon.

wxWidgets XCode

Here you will learn how to install wxWidgets into a Mac and how to configure XCode in order to have the auto-completion for wx and the ability to compile programs written with this library.
First you need to download the sources from: http://www.wxwidgets.org/downloads/ and downloading sources wxMac. Once downloaded, unzip to a directory you like, go to the src folder and you will find an XCode project, open it and compile it in a few minutes you have installed wxWidgets libraries. To do a check just open a terminal and type wx-config - version that will return the version of wx installed.
Well now we're ready to write our first program.
Open XCode:

• create a new empty project "Empty Project", enter the name and specify the folder and press "Finish".

• menu, select "Project" and then "New Target ..." from the section in bold "Carbon" select "Application" and press "next", specify the name and press "Finish"
  

• close the window that has just opened for editing Target, from "File" menu choose "New File ..." menu and bold "C and C + +" select "C + + File" and press “Next”, inserire il nome e premere “Finish”

• dal menu premere “Project” e “Edit Active Target “nome target”, spostarsi nella linguetta “build”

• aprire una console e digitare wx-config --cxxflags, copiare uno a uno tutti i path che iniziano per -I senza il -I e incollarli nella voce “Header Search Paths” nell'editor del target
  

• dalla console selezionare tutte le voci precedute da -D con -D compreso questa volta e copiarle nella sezione “Other C Flags”

• tornare alla console e digitarre “wx-config --libs”, copiare tutto il contenuto e incollarlo nella sezione “Other Linker Flags”

• infine ricercare la voce “ZeroLink” e togliere del tutto la selezione

Fatto questo dovremmo essere pronti per scrivere un programma con la comodità dell’auto completamento e le funzionalità specifiche di XCode per scrivere programmi per il Mac.
Per essere sicuri che tutto funzioni scriviamo l’Hello Word, nel file .h:

  
 #include "wx/wx.h" 
  
 class HelloWorld : public wxApp { 
 virtual bool OnInit(); 
 }; 
  
 IMPLEMENT_APP(HelloWorld) 
  

nel file .cpp :

  
 bool HelloWorld::OnInit() 
 
 {wxFrame * f = new wxFrame (NULL, -1, WXT ("Hello world")); 
 f-> Show (true); 
 return true;} 
 
 

press Build and Run and you should see a beautiful window that says Hello World.
