• When creating a new Monkey project, Monkeydev has injected Libsubstrate.dylib library and Revealserver.framework library into it, and Libsubstrate.dylib library can write logos syntax

• Logos Syntax:

Logos Syntax	function Explanation	Case
%hook	Which class to hook	%hook Classname
%end	code block end Tag
%group	Group	%group Groupname
%new	Add a new method	%new (signature)
%ctor	constructor function	%ctor {...}
%dtor	Destructors	%dtor {...}
%log	Output printing	%log; %log ([(
%orig	Keep the original method	%orig;%orig (arg1, ...) ；
%c		%c ([+/-]class);

1.%hook%end

Specifies the class that needs to be hook, must end with%end.

// hook SpringBoard类里面的_menuButtonDown函数,先打印一句话,再之子那个函数原始的操作%hook SpringBorad- (void)_menuButtonDown:(id)down{    NSLog(@"111111");   %orig; // 调用原始的_menuButtonDown函数}%end

2.%group

This directive is used to group%hook, facilitate code management and conditionally initialize groupings, and must end with%end.
A%group can contain multiple%hook, and all%hook that are not part of a custom group are implicitly categorized into%group_ungrouped.

/*在%group iOS7Hook中钩住iOS7Class的iOS7Method,在%group iOS8Class中钩住iOS8Method函数,然后在%group _ungroup中钩住SpringBoard类的powerDown函数.*/%group iOS7Hook%hook iOS7Class- (id)ios7Method{    id result = %orig;    NSLog(@"这个方法只有iOS7适用");    return result;}%end%end // iOS7Method%group iOS8Hook%hook iOS8Class- (id)ios8Method{    id result = %orig;    NSLog(@"这个方法只有iOS7适用");    return result;}%end%end // iOS8Method%hook SpringBoard- (void)powerDown{     %orig;}%end

3.%new

For use inside%hook, add a new function to an existing class with the same functionality as Class_addmethod.
Note:
The difference between the category of Objective-c and Class_addmethod:
The former is static and the latter is dynamic. Use%new to add, without the need to add a function declaration to the. h file, if you use category, you may encounter such an error.

%hook SpringBoard%new- (void)addNewMethod{    NSLog(@"动态添加一个方法到SpringBoard");}%end

4.%ctor

Tweak the constructor, completes the initialization work; If the definition is not displayed, Theos automatically generates a%ctor and calls%init (_ungrouped) in it. %ctor can generally be used to initialize%group, as well as perform operations such as Mshookfunction, as follows:

#ifndef KCFCoreFoundationVersionNumber_iOS_8_0#define KCFCoreFoundationVersionNumber_iOS_8_0      1140.10#endif%ctor{    %init;    if (KCFCoreFoundationVersionNumber >= KCFCoreFoundationVersionNumber_iOS_7_0 && KCFCoreFoundationVersionNumber > KCFCoreFoundationVersionNumber_iOS_8_0)    %init(iOS7Hook); if (KCFCoreFoundationVersionNumber >= KCFCoreFoundationVersionNumber_iOS_8_0)    %init(iOS8Hook);MSHookFunction((void *)&AudioServicesPlaySystemSound,(void *)&replaced_AudioServerPlaySystemSound,(void **)&orginal_AudioServicesPlaySystemSound);}

5.%dtor

Generate an anonymous deconstructor (of the default priority).

%dtor { … }

6.%log

This directive is used internally in%hook, which writes information such as the class name and parameters of the function to the syslog, which can be%log ([(),.....]) Format to append additional printing information.

%hook SpringBorad- (void)_menuButtonDown:(id)down{    %log((NSString *)@"iosre",(NSString *)@"Debug");    %orig; // 调用原始的_menuButtonDown方法}%end

6.%orig

The directive is used inside%hook to execute the original code of the hook's function, or you can change the parameters of the original function with%orig.

%hook SpringBorad- (void)setCustomSubtitleText:(id)arg1 withColor:   (id)arg2{    %orig(@"change arg2",arg2);// 将arg2的参数修 改为"change arg2"}%end

7.%init

The directive is used to initialize a%group, must be called within%hook or%ctor, or, if with parameters, initializes the specified group, and initializes the _ungrouped if no arguments are taken.
Note: Remember, only call the%init, the corresponding%group can work!

8.%c

The directive is equivalent to Objc_getclass or nsclassfromstring, which dynamically acquires the definition of a class, which is used within%hook or%ctor.
