the button in XibTo add a click event to a button in xib, you need to use the action ibaction. Ibaction is a method that connects to an event on a control in Xib. This method is called when the user triggers this event for the control.Open the auxiliary editor for Xcode as in the previous step, The secondary editing interface displays the TRVIEWCONTROLLER.M file, selects the button object in the Xib, and control-drags the button to the trviewcontroller.m file, releasing the Mouse, which pops up

! Anyway, this interface doesn't have a problem.The queue's handling of the load balance is perfect. For multiple consumer, RabbitMQ is sent to different consumer in a balanced Way (round-robin).4.4 ExchangesAs you can see from the architecture diagram, Procuder Publish's message entered Exchange. Then through the "Routing keys", RABBITMQ will find out which queue the message should be placed in. The queue is also bound by this routing keys.There are three types of Exchanges:direct, Fanout,topic

. RFCThe RFC (Request for Comment) documentation is the official standard for all Ethernet protocols and is published on its official web site, developed by the IETF Standards Association. A large number of RFCs is not a formal standard, and the purpose of publication is simply to provide information. The length of the RFC varies from a few pages to hundreds of pages. Each protocol is identified by a number, such as RFC 3720 is the standard for the ISCSI protocol, and the larger the number, the

1. Getting started with D3D This section provides a brief introduction to D3D Graphic programming interfaces (APIS. Here you will find an overview of the graphic pipeline and a guide to help you implement basic D3D functions.1.1. D3D Architecture This section describes the relationships between Microsoft D3D components, other Microsoft DirectX, operating systems, and system hardware. These topics are discussed below.1.1.1. D3D Architecture Overview Th

I decided to take a few big parts. Today, I started to study in open classes. One is to consolidate my understanding of algorithms, and the other is to share my learning experience. The algorithm class at Princeton University seems to have been completed. There are only handouts, and there seems to be no video. Next I will take an introduction to algorithms at MIT. 　　I am a lazy child. I hope you can supervise me. No supervision, I can't continue, er,

Document directory Application of nutch Introduction Nutch is a Web search engine that is just born with open-source. Although Web search is a basic requirement for roaming the Internet, the number of existing Web search engines is declining. and it is likely to evolve into a company that monopolizes almost all Web searches for commercial benefits. this is obviously not conducive to Internet users. Nutch provides us with suc

Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multiple reducers, the map task will partition the

First understand the Java version: Javame, javase (mainly to create desktop applications, there are independent installers, such as: Windows, MSI, etc.), Java EE (built on the basis of javase, mainly provide Web services, management, etc.). Then is the Java language characteristic, differs from C language, the C language Direct language runs compiles the machine code execution, the efficiency is high, but the Java will first generate a class file (namely bytecode), then interprets the machine co

format syntax covers only the range that plain text can cover. Iii. Introduction to Grammar (i) block elements Paragraphs and line wrapping A markdown paragraph is made up of one or more contiguous lines of text, with more than one blank line before and after it (the definition of a blank line appears to be empty and is treated as a blank line). For example, if a row contains only spaces and tabs, the row is also treated as a blank line. Normal p

　　 Introduction If we had this right now in this example I will use as simple a logic as possible to implement all the functional requirements, which will highlight the core issues we are addressing. Example is a simple calculator class: public class Calculator { public int Add (int x, int y) {return x + y;} } This class is simple enough, but if you think of it as a potentially more complex business processing class, you will face mo

Introduction of views and view 1,views ((1) Views are the main container of application. There can be only one views in an application.(2) The views are also the containers for all View (excluding Modal and Panel). 2,view ((1) View in the application is a separate part, it has its own settings, page switching and history.(2) Each view can have different navigation bars, toolbar layouts, and different styles. So the View is like another application e

People who have used Flex know that there is a PureMVC framework based on MVC, a framework that is popular because it is small and simple. The PureMVC framework has a clear goal of dividing the program into three layers of low coupling: Model, view, and controller. Reducing the coupling between modules and how each module works together is important for creating easily scalable, maintainable applications. In the classic MVC design pattern implemented by PureMVC, these three parts are managed by
