 +====== How to create a Sparrow project from scratch (Xcode 3) ======
  
 +Sometimes, you want to use Sparrow without having the option to use the app scaffold or the Xcode template. This can happen e.g. when you want to integrate Sparrow into an existing project. This is a topic that pops up regularly in the forum.
 +
 +That's why I wrote this tutorial. Don't worry, it's not difficult --- most of the steps have to be followed in any non-trivial iPhone application. However, there are some things that many of us are not accustomed to, like using Xcode'​s source tree variables. ​
 +
 +This tutorial starts from scratch. When you follow it step by step, the outcome will be a project just like the app scaffold that's part of Sparrow. Good luck!
 +
 +<note warning>
 +This article is about Sparrow 1.x!\\ ​
 +For Sparrow 2.x, please visit [[Creating a Sparrow Project from Scratch]].
 +</​note>​
 +
 +==== 1. Set up the Sparrow project reference ====
 +
 +
 +  - Create a new "​Window-based"​ iPhone Application
 +  - Open your project in Xcode
 +  - In the "​Groups & Files" pane of Xcode, add the Sparrow project (Sparrow.xcodeproj) by selecting the project root and hitting ''​Option+Cmd+A''​ (add to project)
 +  - When the "Add to Project"​ dialog is displayed, use the following settings:
 +    * Copy items (...): no
 +    * Reference Type: Relative to ''​SPARROW_SRC''​
 +    * Text Encoding: ''​UTF-8''​
 +    * Recursively create groups for any added folders: yes
 +
 +==== 2. Configure the Library Dependencies,​ Linking, and Header Files ====
 +
 +  - Click on "​Project - Edit Project Settings"​. Click on the build tab and scroll down to the "​Search Paths" section.
 +  - Set "User Header Search Paths" to: ''​${SPARROW_SRC}'',​ recursive: yes
 +  - Still in the Build-settings,​ under "Other Linker Flags" add: ''​-ObjC''​ and ''​-all_load''​ **(this is important!)**
 +  - Click on "​Project - Edit Active Target"​. Then select the general tab and add Sparrow to the "​Direct Dependencies"​.
 +  - In the same Window, under "​Linked Libraries",​ add "​AudioToolbox.framework",​ "​AVFoundation.framework",​ "​OpenAL.framework",​ "​OpenGLES.framework",​ and "​QuartzCore.framework"​
 +  - Finally, click and drag "​libSparrow.a"​ from underneath the cross-project reference to "​Targets - [your target] - Link Binary with Libraries."​
 +
 +==== 3. Create the base Source Classes ====
 +
 +//Create Game.h://
 +
 +<code objc>
 +#import <​Foundation/​Foundation.h>​
 +#import "​Sparrow.h"​
 +
 +@interface Game : SPStage
 +
 +@end
 +</​code>​
 +
 +//Create Game.m://
 +
 +<code objc>
 +#import "​Game.h"​
 +
 +@implementation Game
 +
 +- (id)initWithWidth:​(float)width height:​(float)height
 +{
 +    if (self = [super initWithWidth:​width height:​height])
 +    {
 +        // this is where the code of your game will start. ​
 +        // in this sample, we add just a simple quad to see 
 +        // if it works.
 +
 +        SPQuad *quad = [SPQuad quadWithWidth:​100 height:​100];​
 +        quad.color = 0xff0000;
 +        quad.x = 50;
 +        quad.y = 50;
 +        [self addChild:​quad];​
 +    }
 +    return self;
 +}
 +@end
 +</​code>​
 +
 +//Modify ProjectAppDelegate.h://​
 +
 +<code objc>
 +#import <​UIKit/​UIKit.h>​
 +#import "​Sparrow.h"​
 +
 +@interface ProjectAppDelegate : NSObject &​lt;​UIApplicationDelegate&​gt;​
 +{
 +    UIWindow *window;
 +    SPView *sparrowView;​
 +}
 +
 +@property (nonatomic, retain) IBOutlet UIWindow *window;
 +@property (nonatomic, retain) IBOutlet SPView *sparrowView;​
 +
 +@end
 +</​code>​
 +
 +//Modify ProjectAppDelegate.m://​
 +
 +<code objc>
 +#import "​ProjectAppDelegate.h"​
 +#import "​Game.h"​
 +
 +@implementation ProjectAppDelegate
 +
 +@synthesize window;
 +@synthesize sparrowView;​
 +
 +- (void)applicationDidFinishLaunching:​(UIApplication *)application ​
 +{    ​
 +    SP_CREATE_POOL(pool); ​   ​
 +    ​
 +    [SPStage setSupportHighResolutions:​YES];​
 +    [SPAudioEngine start];
 +    ​
 +    Game *game = [[Game alloc] init]; ​       ​
 +    sparrowView.stage = game;
 +    [game release];
 +    ​
 +    [window makeKeyAndVisible];​
 +    [sparrowView start];
 +    ​
 +    SP_RELEASE_POOL(pool);​
 +}
 +
 +- (void)applicationWillResignActive:​(UIApplication *)application ​
 +{
 +    [sparrowView stop];
 +}
 +
 +- (void)applicationDidBecomeActive:​(UIApplication *)application ​
 +{
 +    [sparrowView start];
 +}
 +
 +- (void)dealloc ​
 +{
 +    [sparrowView release];
 +    [window release];
 +    [super dealloc];
 +}
 +@end
 +</​code>​
 +
 +==== 4. Create a Sparrow View ====
 +
 +  - Open "​MainWindow.xib"​ in the interface builder
 +  - Drag a "​UIView"​ into the main application window
 +  - In the properties of the View, set the class manually to "​SPView"​ (topmost entry in the rightmost tab).
 +  - If you need support for multitouch, activate it in the leftmost tab
 +  - Make a connection to the ''​sparrowView''​-property of the Application Delegate (in the connections-tab of the Application Delegate, drag a line from the ''​sparrowView''​-property to the new view).
 +  - Save the file and quit interface builder.
 +
 +==== 5. Phew! Done! (Hopefully) ====
 +
 +If everything works, you should see a window with a red square. Congratulations!
