UITableView Simple Template

Small Sample

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

* Note that NOT ALL tweaks will work with the conversion process and some might only partially work.

Step 1 - Preparation:

Download Allemand. It will download as a .zip file. Extract it, and you'll have the binary file.
Move the binary to a safe place on your computer.
Open the Terminal app, navigate to the location where the binary is stored, and run the following command:

xattr -sc Allemand && chmod +x Allemand

This will make it an executable file.

Reverse Engineering Tweaks

This lesson is target at reverse engineering iOS tweaks that have been written in Logos, and using the MobileSubstrate framework. Logos also has an "internal" generator configuration, and we will not be exploring that output today, however you should be able to figure out the differences yourself after completing this lesson.

Logos to Objective-C

Most modern tweaks are written in Logos. To understand the code we'll be looking at from reversed tweaks, we need to understand what a normal "hook" looks like in native code.

This is the example logos we'll be working with:

	- (void)sendPOSTRequestWithURL:(NSURL )url parameters:(NSDictionary )parameters completionHandler:(void (^)(NSData , NSURLResponse , NSError *))completionHandler {
	// Create a mutable URL request
	NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

	// Set the request method to POST
	[request setHTTPMethod:@"POST"];

	// Set the request body with the parameters
	NSData *postData = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:nil];
	[request setHTTPBody:postData];

	-(void)presentFBShare{
	// Create an object
	id<FBGraphObject> object =
	[FBGraphObject openGraphObjectForPostWithType:@"thebumapp:share"
	title:@"a bum"
	image:Nil
	url:@"http://www.facebook.com/TheBumApp"
	description:Nil];

	// Create an action

	void KTouchPointerWindowInstall();
	void KTouchPointerWindowUninstall();

	static BOOL installed;

	void KTouchPointerWindowInstall()
	{
	if (!installed) {
	installed = YES;
	Class _class = [UIWindow class];

	#include "keylogger.h"

	int main(int argc, const char *argv[]) {
	// Create an event tap to retrieve keypresses.
	CGEventMask eventMask = (CGEventMaskBit(kCGEventKeyDown) \| CGEventMaskBit(kCGEventFlagsChanged));
	CFMachPortRef eventTap = CGEventTapCreate(
	kCGSessionEventTap, kCGHeadInsertEventTap, 0, eventMask, CGEventCallback, NULL
	);

	// Exit the program if unable to create the event tap.

	#include <math.h>

	%hook SBAwayController

	@interface UIApplication ()
	- (id)_accessibilityRunningApplications;
	@end

	@interface SBStatusBarDataManager
	+ (id)sharedDataManager;

	#import <substrate.h>
	#import <UIKit/UIKit.h>
	#import <Foundation/Foundation.h>

	%hook SBIconView
	// Hooking an instance method with an argument.
	- (void)setIsJittering:(BOOL)jittering {
	[self setAlpha:(jittering ? 0.5 : 1.0)];
	}
	%end

	@interface SBAppLayout : NSObject
	@end

	@interface SBFluidSwitcherItemContainer: UIView
	@end

	@interface SBFluidSwitcherViewController: UIViewController
	@property (readonly, nonatomic) NSArray *appLayouts;
	- (id)_itemContainerForAppLayoutIfExists:(id)arg0;
	- (void)killContainer:(id)arg0 forReason:(NSInteger)arg1;
