The reason why the classnamebase operation is performed on the instance class name is that the class The Org. Apache. hadoop. IPC. server class is the core of the RPC server. Its important data members are as follows: Member Description StaticThreadlocal Server Indicates the object of the currently running rpc server, that is, the server

A responder chain1.1hitTest:withEventThis function returns the view on which the touch point is located when the touch event occurs. function execution principle is as followsIf the user clicked View E, the following describes the Hit-test view process1, A is the root view of UIWindow, therefore, the Uiwindwo object will be the prime minister of a hit-test;2, obviously the user clicks the scope is within the range of a, therefore,pointinside:withevent

Introduction: Event Handling in iOS is a very important and very rare place. It involves the response of the local side of the chain of questions, very much work two or three years old birds may not be able to answer very professional. Here's a detailed description of event handling in iOS and the responder chain.1. Three major events Touch events Speeding up the timekeeping room Remote control Events 2.

Get the current first response object From this discussion: Http://stackoverflow.com/questions/1823317/get-the-current-firsT-responder-without-using-a-private-api The guy who asked the question used the following way to get Copy Code code as follows: UIView *firstresponder = [Keywindow Performselector: @selector (FirstResponder)]; The result is the Apple called back, said the use o

The key here is to set up a new socket for non-blocking, which is based on performance considerations, non-blocking ways to read the data in the socket receive buffer as much as possible, This guarantees that the future will call this socket to receive the reader and send the responder thread will not be b

event queue. When processing events, UIApplication extracts the first event from the event queue and distributes it for processing. Generally, it sends the event to the main window. Then, the main window passes the event to an initial object for processing, this object is Touch events for a Touch event. First, the event is sent to the most appropriate object for processing. For a touch event, this object refers to the hit-test view. For other events, this object refers to the first

) previuslocationinview :( uiview *) view: This method records the previous coordinate value, and the function returns a value of the cgpoint type,The position of the touch on the view. The position returned here is for the coordinate system of the view. If the input view parameter is null during the call, the returned touch point is in the position of the entire window. When your fingers touch the screen, whether it's single point of touch or multi-point touch, the event starts until all your f

distributed to the target object. If the target is not specified, the application is responsible for retrieving the appropriate response. It defines a set of methods for assigning and managing contacts in an application. These responders make up what we knowResponder chain-That is, a series of responders, and event or action messages are transmitted between them until the objects that can be processed are found. The responder chain is the centra

As we all know, JSON is a data format unrelated to the platform, so it is also recognized by the majority of programmers. At present, third-party LIB in various JSON formats are emerging one after another, just like Spring Festival, in the face of this, how should we choose? First, let's compare the current performance of the JSON Parsing Library: json becnhmark1_protolethose test are generate by parrsing 50.000 pre-build json string. to minimize gc effect on login, a new VM is lanched for each

any event that can be processed. For example, "catch a cold", "fire", "collapse", and "object passing through ". Responder-indicates any object interested in an event. Responder-indicates the response of objects of interest to an event to a specific event. Specifically, for the process: Notification-occurs between the event and the responder. We divide it

Talking about gestures and touch in iOS, talking about iOS gesture touch I. response chain Various operation events will be encountered in IOS development, and these events can be responded through the program. First, when an event responds, you must know who will respond to the event. In IOS, the responder chain responds to events. All Event Response classes are subclasses of UIResponder. The responder cha

When we use micro-letters and other tools, click Sweep, you can open two-dimensional Code scan view. When we clicked on the screen, the iphone OS captured the user's "click" Behavior, and the operating system packaged the information that contained these click events into Uitouch and uievent forms, and then found the currently running program, looking for an object that could respond to the event. Until there is no responder response. This search proc

event queue, where UIApplication takes the first event from the event queue and distributes the processing, when the event is processed. Normally he will send it to the main window, and the main window will then pass the event to an initial object, which is touch eventsThe event is first sent to the most appropriate object for processing. For touch events This object refers to Hit-test view, which refers to the first responder for other events.UIKit

Event Handling Responder Object Not all objects in iOS can handle events, only objects that inherit Uiresponder can receive and handle events. We call it "responder object." UIApplication, Uiviewcontroller, and UIView inherit from Uiresponder, so they are both responder objects that can receive and handle events Uiresponder internally provides t

The function returns a CGPoint value, indicating the position of the touch on the view, the returned position is the coordinate system of the view. If the input view parameter is null during the call, the returned touch point is in the position of the entire window.When your fingers touch the screen, whether it's single point of touch or multi-point touch, the event starts until all

13.1 event Overview 13.2 touch events 13.3 gestures 13.1 event Overview An event is the object that the system continuously sends to the application when the user's fingers touch the screen and move on the screen. The system passes an event to an object that can be processed according to a specific path. In iOS, A uitouch object represents a touch, and a uievent object represents an event. The event object contains all the touch objects corresponding to the current multi-point touch sequence.

three main cases where UIView does not accept event handling:1) Alpha 2) userinteractionenabled = NO3.hidden = YESThe following comes from the network:Responder chain Concept: When the iOS system detects a finger touch operation, it packs it into a Uievent object and puts it into the event queue of the currently active application. The uiapplication of a singleton takes a touch event from the event queue and passes it to the uiwindow of the Singleton, UIWindow object first uses the Hittest:with
