With this wonderful tool, you can now update the open toolchain header from your SDK. This works for the iPhone SDK

http://www.hackint0sh.org/forum/show...ght=class-dump

Updated: class-dump-x (It works for iPhone binary as well)
http://iphone.freecoder.org/classdump_en.html

For example, run this to dump all the header files for UIKit to your current directory.

Code:

class-dump -H /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.0.sdk/System/Library/Frameworks/UIKit.framework/UIKit

If you use this method to update the header files of open toolchain, some header files will have this at the start

Code:

#import "NSObject.h"

and you have to change it to

Code:

#import <Foundation/NSObject.h>

in order to remove the compiler missing file error.

In order to make use of the UITouch and UIEvent in the SDK for the open toolchain project, you can update the header file using the class-dump.

Alternatively, you can add the following headers in order to use the touch handling events (such as touchesBegan, touchesMoved and touchesEnded methods etc) in the SDK

Code:

typedef unsigned int NSUInteger;
#import <UIKit/UITouch.h>
#import <UIKit/UIEvent.h>

To demonstrate the use of these touch handling events such as double tap and swipe, here is a sample code for the open toolchain header. This has been tested under SDK beta3 and iPhone OS 2.0 5A240d (pwned)

If you use SDK beta2 to compile, there will be error as Apple has changed the enum of UITouch in SDK beta3

Code:

/*

 main.m

You need UIAccelerometer.h, in order to use the Accelerometer for the firmware 2.0 using the open toolchain API

Code:

#import <UIKit/UIAccelerometer.h>

There is an example code for the Accelerometer using the open toolchain (for firmware 1.1.x) by Erica Sadun
http://www.tuaw.com/2007/09/10/iphon...accelerometer/

But the code will not work under iPhone OS 2.0 as Apple has changed the API. You need to add UIAccelerometer.h, override the accelerometer: didAccelerate: method and set the delegate.

Code:

- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration;

Here is the sample code that modified from the original (as in those #ifdef ASPEN blocks) in order to build and run using the open toolchain template for the SDK of this thread

I have added the meaning of X, Y, Z in the sample code as per Erica, but the range of values should now go from 1.0 to -1.0

/*
The meaning of X, Y, Z by Erica Sadun
X = Roll X corresponds to roll, or rotation around the axis that runs from your home button to your earpiece. 
    Values vary from 0.5 (rolled all the way to the left) to -0.5 (rolled all the way to the right).

Y = Pitch. Place your iPhone on the table and mentally draw a horizontal line about half-way down the screen. 
    That's the axis around which the Y value rotates. 
	Values go from 0.5 (the headphone jack straight down) to -0.5 (the headphone jack straight up).

Z = Face up/face down. I expected the Z value to correspond to yaw. And it does not. 
    It refers to whether your iPhone is face up (-0.5) or face down (0.5). 
	When placed on it side, either the side with the volume controls and ringer switch, or the side directly opposite
	, the Z value equates to 0.0.

Multitouch is default disabled in the UIView for firmware 2.0 SDK. To enable it

Code:

	[myView setMultipleTouchEnabled:YES];

this method is not in the Open Toolchain header but in the class-dump of SDK and also in the property directives of the SDK header file here

Code:

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIView.h

The property directives offer some convenient ways of getter and setter methods for the Objective C 2.0, such as

Code:

	gameView.multipleTouchEnabled=YES;
	xarrow.hidden = !debuginfo;
	label1.hidden = imgView.hidden = NO;
	imgView.center = mainView.center;

It is better to add these property directives to the project file, and once added, the property directives are available to the UIView class and its subclasses e.g. UIImageView

Code:

#import<UIKit/UIView.h>

typedef int NSInteger;

typedef enum {
    UIViewAnimationCurveEaseInOut,         // slow at beginning and end
    UIViewAnimationCurveEaseIn,            // slow at beginning

For the multitouch app of firmware 2.0, I have ported a game called T4Two to firmware 2.0 beta

The original project is at (with source and binary for 1.1.x)
http://www.iamas.ac.jp/~aka/iphone/#T4Two.app

This game allows two players to control the rackets on the multitouch screen with sound.

I have added the following enhancements:
(a) double tap on the screen to toggle debug touch position information on the screen
(b) triple tap on the screen to toggle sound (default is changed to no sound)

The Accelerometer is turned off, as this has problem with the multitouch for the beta, but you can turn it on by #define ENABLE_ACCELEROMETER in the source code and build again.

The program will run on firmware 2.0 beta 3 and has been tested on iPhone firmware 2.0 beta 3 (pwned). The source code and makefile will build on SDK beta 3 with Open Toolchain header. I think SDK beta 5 will also work, but I did not try.

The compiled binary T4Two.app folder (for firmware OS 2.0 beta 3 build 5A240d) is at
http://www.iphone.org.hk/attach/29958-T4Two.zip
MD5 (29958-T4Two.zip) = aa5c2868289cf53af7395d0f5dbdfc04

To install, just scp to the /Applications folder, or wget directly and unzip in iPhone.

If you don't have wget in iPhone, get it from here, this wget binary works in firmware 2.0 beta 3
http://ericasadun.com/ftp/PortedUtilities/

Code:

 
wget http://www.iphone.org.hk/attach/29958-T4Two.zip  
unzip -oj 29958-T4Two.zip build/2.0/T4Two.app/* -d /Applications/T4Two.app

Xcode Template with Open Toolchain headers to run UIShowCase sample app

There is a sample app from Apple SDK called UIShowCase (non Interface Builder version) for SDK beta 3. This sample app uses a lot of UIKit classes that are missing from the open toolchain headers. In order to use these UIKit classes in the SDK, I have created a patched local header #import "UIKit.h", so that it can be build and run using open toolchain Xcode template. The patched header will be added to the Xcode template of this thread.

To build the app, the UIShowCase sample code should be amended as

Code:

/*
 main.m
*/
#ifdef ASPEN
#import "UIKit.h"
#import "AppDelegate.h"
#else
#import <UIKit/UIKit.h>
#endif

int main(int argc, char *argv[]) {
	int returnCode;
	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
#ifdef ASPEN
	returnCode = UIApplicationMain(argc, argv, [AppDelegate class]);
#else
	returnCode = UIApplicationMain(argc, argv, nil, @"AppDelegate");
#endif
	[pool release];
	return returnCode;
}

Code:

/*
File: AppDelegate.h
*/

#ifdef ASPEN
#import "UIKit.h"
@interface AppDelegate : UIApplication
#else
#import <UIKit/UIKit.h>
@interface AppDelegate : NSObject <UIApplicationDelegate>
#endif

{
    UIWindow *window;
	UINavigationController *navigationController;
}

@end

and for every .h header files of the UIShowCase app that use #import <UIKit/UIKit.h>, they should also be changed to

Code:

#ifdef ASPEN
#import "UIKit.h"
#else
#import <UIKit/UIKit.h>
#endif

With this local "UIKit.h" header file, you can now use most of the new UIKit classes
from the SDK in the open toolchain header template.

To get the local "UIKit.h", you can install the version 2 of this Xcode Template

The installation instruction for version 2 of the Xcode Template is to use the following commands in Mac Terminal

Code:

curl http://cocoatouchdev.com/javacom/ToolChainTemplate_v2.zip  > ToolChainTemplate_v2.zip 
unzip ToolChainTemplate_v2.zip -d "/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Project Templates"

MD5 (ToolChainTemplate_v2.zip) = 64f547c961818404e4a1cf2764e7c285

If I create a project using the Cocoa Touch Toolchain template and build it I get the following error:

Build failed (1 error)

Any ideas?

It supports build to device and "release" only, if you use Xcode.

Or you can use the Makefile that is included in the project template.

Oh sorry I missed that. A new project builds fine in release if you choose Toolchain Build, but the UIKit.h included in Cocoa Touch Toolchain fails because its redefining many of the enums.

Anyway my real problem is that when I add the IOKit framework:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/Frameworks/IOKit.framework

When I build Xcode reports framework IOKit not found...I haven't figured out how to include the IOKit headers yet too, I expect to be able to include the IOKit include directory for the normal intel sdk.

When porting some 1.1.x games app to 2.0 firmware and in order to use the open toolchain methods for event handling such as

Code:

- (void)mouseDown:(struct __GSEvent *)fp8;
- (void)mouseUp:(struct __GSEvent *)fp8;
- (void)mouseDragged:(struct __GSEvent *)fp8;
- (void)mouseEntered:(struct __GSEvent *)fp8;
- (void)mouseExited:(struct __GSEvent *)fp8;
- (void)mouseMoved:(struct __GSEvent *)fp8;

You need to add this in main.m

Code:

    UIApplicationUseLegacyEvents(1);

Otherwise, you have to rewrite the touch handling events into these methods using the firmware 2.0 UITouch and UIEvent headers as in my previous post (T4Two.app)

Code:

- (void)touchesBegan:(id)fp8 withEvent:(id)fp12;
- (void)touchesMoved:(id)fp8 withEvent:(id)fp12;
- (void)touchesEnded:(id)fp8 withEvent:(id)fp12;

I have ported a game called tris to firmware 2.0 beta using these 2 approaches, but I found out that the performance of UITouch/UIEvent handling events are slightly better in firmware 2.0 beta, so the compiled binary uses the firmware 2.0 methods.

The original project is at (with source and binary for 1.1.x)
http://code.google.com/p/tris/

This game supports suspend and resume and I have added a quit menu, so that it can be remove from background completely.

You can enable the firmware 1.x event handling methods (that is to disable firmware 2.0 event handling methods) by uncomment this line in the Makefile and run make again

Code:

#CFLAGS += -DUSE_LEGACY_EVENT

The program will run on firmware 2.0 beta 3 and has been tested on iPhone firmware 2.0 beta 3 (pwned). The source code and makefile will build on SDK beta 3 with Open Toolchain header.

The compiled binary tris.app folder (for firmware OS 2.0 beta 3 build 5A240d) is at
http://www.iphone.org.hk/attach/30626-tris.zip
MD5 (30626-tris.zip) = 08a155605419317843084c04648be5eb

To install, just scp to the /Applications folder, or wget directly and unzip in iPhone.

If you don't have wget in iPhone, get it from here, this wget binary works in firmware 2.0 beta 3
http://ericasadun.com/ftp/PortedUtilities/

Code:

 
wget http://www.iphone.org.hk/attach/30626-tris.zip  
unzip -oj 30626-tris.zip build/2.0/tris.app/* -d /Applications/tris.app

The source code, resources and Makefile are at
http://www.iphone.org.hk/attach/30631-tris_src.zip

There are problems using setFont setColor methods in UITextLabel and UITextView in the sdk compiler and open toolchain headers

Typically the code for setFont and setColor in firmware 1.1.x would be

Code:
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
float grayComponents[4] = { 0.3, 0.3, 0.3, 1. };
UITextLabel* label;
[label setFont:[NSClassFromString(@"WebFontCache") createFontWithFamily:@"Helvetica" traits:0 size:17.]];
[label setColor:CGColorCreate(colorSpace, grayComponents)];
When porting these codes using the sdk compiler and the open toolchain headers to firmware 2.0, the iPhone OS 2.0 runtime will fail and show this error in the Xcode Organizer

Code:
[NSCFType CGColor]: unrecognized selector sent to instance
The reason is that the struct __GSFont and struct CGColor are not recognized in iPhone OS2.0 and it can be solved by including these in the code and used the new UIFont and UIColor methods in the SDK headers


Code:
typedef float CGFloat;
#import <UIKit/UIFont.h>
#import <UIKit/UIColor.h>


These two header files are in here and there are some new methods defined

Code:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/Frameworks/UIKit.framework/Headers
There are two methods to convert these 1.1.x codes using setColor:CGColor to firmware 2.0 as below

Code:
firmware 1.1.x code
float grayComponents[4] = { 0.3, 0.3, 0.3, 1. };
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
[label setColor:CGColorCreate(colorSpace, grayComponents)];

firmware 2.0 code method 1 (using CGColor)
float grayComponents[4] = { 0.3, 0.3, 0.3, 1. };
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
[label setColor:[UIColor colorWithCGColor:CGColorCreate(colorSpace, grayComponents)]];

firmware 2.0 code method 2 (using Color Components)
[label setColor:[UIColor colorWithRed:0.3 green:0.3 blue:0.3 alpha:1.0];

The following sample code demonstrates the use of UIFont and UIColor methods and will display the useless "Hello ToolChain" in iPhone OS 2.0 (pwned) if you use the Xcode template of this thread to build

There will be warning messages when build and just ignore them. To remove these warnings, the open toolchain headers should be amended.



Code:
/*
HelloToolChain.app
main.m
*/
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

// include for the sdk compiler and open toolchain headers
#ifndef UIKIT_UIFont_UIColor_H
#define UIKIT_UIFont_UIColor_H
typedef float CGFloat;
#import <UIKit/UIFont.h>
#import <UIKit/UIColor.h>
#endif
