Target-action: Target-action mode, which runs through iOS development always. But for beginners, it is still confused by this pattern.In fact, the target-action pattern is simple, that is, when an event occurs, call that method in that object. For example: When the button is pressed, the click Method inside the controller is called. "That object" is

Articles translated from https://www.objc.io/issues/7-foundation/communication-patterns/Each application, more or less, consists of loosely coupled objects (modules) that must communicate with each other to complete their work. This article will use the communication mechanisms available and give an example of the Apple framework and provide the best practice recommendations on which communication mechanisms are used.Although this issue is about the foundation framework, we can use the communica

The port is the current computer and outside the channel, so once the hacker locks the target computer, it will scan the computer is already open port, so as to get more useful information. Scan destination computer ports generally use Superscan, X-scan, and so on.First, the principle of port scanningBefore scanning the port, the user must understand how the port scan works. Simply put, the principle is to use the data packet to analyze the response o

Target-Action in iOS Design PatternTarget-Action (Target-action) mode (aims to decouple the code, reduce the correlation between the code and the code, and facilitate future development and maintenance) Target-Action-a button used in this design mode, and other controls to turn user interaction into code, so that the program can execute;

Cross-compiling the meaning of Host,build target: Build is the machine you are using, and host is the platform you can run with the compiled program, Target is the platform that your compiled program can handle. This build and host are better understood, but target is difficult to do, what does it mean? In general, we do not usually speak of the compilation of th

Tags: gdbserver armv4t codesourcery因某种需要，要在Windows平台上进行程序开发，目标板是基于Micrel芯片（ARMv4t）做的，上面运行有Linux最小系统，只有最基本的命令，需要在Windows平台上交叉编译能在ARMv4t上运行的目标代码，并且还要能进行远程调试。基于这些需求，初步计划按以下步骤进行: 1、先在Windows平台上交叉编译一个简单的C语言程序，并上传到开发板上，能正常运行即可； 2、交叉编译gdbserver，并上传到开发板； 3、进行远程调试。 按上述计划，首先要找一个Windows环境下的交叉编译环境，参考了http://www.veryarm.com/arm-none-linux-gnueabi-gcc 下载了arm-2011.03-41-arm-none-linux-gnueabi.exe Windows安装版（个人感觉在Windows下用安装版比较好，解压版需要设定PATH），安装成功后，用C写了一个简单的Hello，World！，使用如下命令进行编译： ARM-NONE-LINUX-GNUEABI-GCC Hel

after completing the preparation and configuration of the full eight chapters above, the target device can now be created, the diskless PC will boot with PXE, and PVS uses streaming technology to dynamically and in real time push disk data from a single shared image to the corresponding PC (i.e. target device). However, after creating the target device, the norma

I don't like to eat a buffet, because every time I eat a buffet, I was always full. I went out a few steps and went hungry again. Taking a closer look, in fact, most of the time in the buffet is spent in the slide before the dish selection table. This is a problem caused by unclear goals. When the target is doing the "Brown Movement", it seems that you are working. In fact, all your efforts are spent in inaction, and these choices will be quickly over

Topic As the research focus is on computer image processing, A Study on Image Segmentation is currently underway. The process of splitting the target image from the original image has basically been completed. Now we are numbering the target image, and I am using the four adjacent domain labels.AlgorithmThe algorithm is self-implemented, but now there is a problem: the

Original article, reproduced Please note: http://blog.csdn.net/crzy_sparrow/article/details/7414851 If the camera is fixed, we can consider that the scene (background) remains unchanged in most cases, and only the foreground (the target to be tracked) moves, so that we can establish a background model. By comparing the current frame and background model, you can easily track the target motion. Here, the ea

It is used to match the target element of a marker in the URI of the document (page).
