Previous post, talking about using Iosopendev to develop Theos-based tweak, the function hooks springboard -(void) applicationdidfinishlaunching: (ID) Application.
First of all, Hook,hook Chinese translation as "hook", very image, with a post as an example, we use substrate to hook, iOS devices run to the applicationdidfinishlaunching method, We hooked up the execution stream and let the device run our own implementation code. In addition, Hook is not unique to iOS, is a "patch technology", in the absence of source code, we can use the hook to achieve our goal, any operating system platform has a variety of hook methods, not limited to iOS.
The code in the previous post has a% beginning of the statement, this is Theos logos pre-processing instructions, the English document is not long, the syntax is simple, I am unknown here.
The detailed documentation is described in Http://iphonedevwiki.net/index.php/Logos
