## Tweak.xm

/* How to Hook with Logos
 Hooks are written with syntax similar to that of an Objective-C @implementation.
 You don't need to #include <substrate.h>, it will be done automatically, as will
 the generation of a class list and an automatic constructor.

 %hook ClassName

 // Hooking a class method
 + (id)sharedInstance {

    #Loading Tweaks in the Simulator
With the latest updates to the simulator, this turns out to be pretty simple:
You need to be using kirb/theos
In order not to require MobileSubstrate to be loaded and your tweak to be compiled for i386/x86_64, add
In your makefile:


## add.c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int addi(int a, int b) {
    return a + b;
}

char *adds(char *a, char *b) {
    char *res = malloc(strlen(a) + strlen(b) + 1);

## Screenshot
To get the background I use _UICreateScreenUIImage();
Here's the declaration:
OBJC_EXTERN UIImage *_UICreateScreenUIImage(void) NS_RETURNS_RETAINED;
Specifically I hook SBBackLightController.  Here is the bare bones of what I use:


%hook SBBacklightController
- (void)animateBacklightToFactor:(CGFloat)factor duration:(double)duration source:(int)source completion:(void (^)(void))completion {
	if (factor < 0.1) {
		UIImage *currentBackground = _UICreateScreenUIImage();

	// Control Centre gesture
	SBOffscreenSwipeGestureRecognizer *gesture = [[SBOffscreenSwipeGestureRecognizer alloc] initForOffscreenEdge:0x4];
	[gesture setTypes:0x40];
	[gesture setShouldUseUIKitHeuristics:YES];

                This is my technical interview cheat sheet. Feel free to fork it or do whatever you want with it. PLEASE let me know if there are any errors or if anything crucial is missing. I will add more links soon.
              
          
    ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
