(accessing Fundebug slows down ). To solve the two problems of OCSP, We have OCSP stapling. The website server performs OCSP queries, caches the query results, and returns the results to the browser during TLS connection with the browser, so that the browser does not need to query the results again. This solves the problemPrivacyAndPerformanceProblem.OCSP stapli

I. Classification of eventsFor iOS device users, there are three main ways to manipulate devices: Touch the screen, shake the device, and control the device through a remote controlled facility. The following three types of events are available:1. Touchscreen events (Touch event)2, motion events (motion event)3. Remote Control Events (Remote-control event)Today, as an example of touch event, the process of handling events in the Cocoa Touch framework is illustrated. First we have to introduce th

In iOS, the event Uievent class indicates that when an event occurs, the system collects related event information, creates an Uievent object, and finally forwards the event to the Application object (uiapplication). In daily life, there are three main types of events: Touch events, accelerometer events, and remote control events. Here is an official picture:When a user triggers an event by doing so, the corresponding event object is added to the UIApplication event queue. The uiapplication loop

This method is to find the view is touch, when found to become the first of the response chain, if he can not handle the event, then find Nextresponder until application if not processed, it will be discarded.Https://developer.apple.com/library/ios/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/event_ Delivery_responder_chain/event_delivery_responder_chain.htmlThe following is an official explanation.Event delivery:the Responder ChainWhe

I have a basic understanding of the responder chain concept encountered in iOS development in a previous blog, "iOS responder chain responder chain." But it is not enough to stay on the basis of understanding the concept. This blog will be a code case for a deeper understanding of the response chain. An example of this blog is uploaded to Https://github.com/cheny

initializes the dependency event type. Touch Events. For touch events, the Window object first attempts to pass an event to the view that the event occurred. This view is the so-called Hit-test view. The way to find Hit-test view is called Hit-testing, which describes the "hit-testing Returns the View Where a Touch occurred." action events and Remote control events (motion and remotes). In these events, the Window object sends an event to the first

In iOS, when an event response occurs, you must know who is responding to the event. This is the response of the responder chain to the event, all the event response classes are Uiresponder subclasses, the responder chain is a hierarchy of different objects, each of which will sequentially get the opportunity to respond to event messages. When an event occurs, the event is first sent to the first

Responder objects (Response object)The responder object is the ability to respond to events and handle events. In iOS, there is a Uiresponder class that defines all the methods of the responder object. UIApplication, UIView and other classes inherit the Uiresponder class, and the controls in UIWindow and Uikit inherit UIView, so they inherit uiresponder classes i

This article link address : http://www.linuxidc.com/Linux/2015-08/121270.htmFirst, let's look at the process of generating and passing events in iOS:1. After a touch event occurs, the system adds the event to a queue event managed by uiapplication2.UIApplication takes the first event out of the event queue and distributes the event for processing, typically sending an event to the application's main window (Keywindow)3. The main window will find the most appropriate view in the view hierarchy to

Responder Chain Concept:Each application has a responder chain, our view structure is an n-fork tree (a view can have multiple sub-views, a child view has only one parent view at a time), and every object that inherits Uiresponder can play a node in this N-fork tree. When the leaf node becomes the highest responder, starting from this leaf node to its parent node

Event Delivery: The Responder Chain (Event passing, response Chain), deliveryresponder When designing an app, we may want to respond dynamically to events. For example, to touch a screen with many different objects, you need to decide which object to send a response event and how the object receives the event. When a user generates an event (such as a click), UIKit generates an object that contains the information of the object to be processed. Then,

In iOS, events fall into three categories: Touch events: Trigger by Touch, gesture (click, zoom, etc.) Motion events: Triggering via an accelerator (shaking, etc.) Remote control event: triggered by other remote device (line-controlled headset) Only classes that inherit from Uiresponder can handle eventsHere's a touch event.When the user touches the screen, the event is encapsulated into an event instance, which contains the touch-related information, which is then distribu

processing. This initial object depends on the type of event. Touch events. For touch events, the Window object first attempts to send an event to the view (Hit-test view) where the event occurred. The process of finding hit-test view is called hit-testing (we'll talk about it in the back). Motioin and remote control enents. Such events, window shrimp ing send shaking-motion or remote control event to the first responder processing.

The process of delivering a complete touch event with a delivery responseUIApplication---UIWindow to find the most appropriate control for handling eventsThe control calls the touches method and determines whether the touches method is implemented, and no implementation defaults to passing the event to the previous responder--Finding the previous responderPS: If it doesn't respond to uiapplication, then the event is discarded.1.

An event responder object is an object that can respond to an event and process it, and the responder chain is made up of a series of linked respondents. The responder chain is very important in event handling, and the
