Overall, there are 2 steps:One, find the right control from top to bottom to handle this touch event. For example, if you click Yellow 4, then uiapplication, UIWindow, 1 white, 2 orange, 3 blue and 4 yellow.Second, find 4 yellow, then from bottom to top traverse the responder chain: 4 yellow, 3 blue, 2 orange, 1 white, UIWindow, uiapplication1) If 4 yellow realizes the touches ... These functions (specifically the second one below) and do not call sup

Question 1: What events are there in IOS? • Various events are generated when a user uses an app. • Events in IOS can be divided into three major types. Question 2: What is a responder object? • In iOS, not all objects can process events. Only objects that inherit uiresponder can receive and process events. We call it "responder object". • uiapplication, uiviewcontroller, and uiview all inherit from uirespo
the baseview, no response is returned when you click a location outside the baseview. Click viewa.
Example B: viewa, viewb, and viewc both implement hittest and call Super hittest. viewd and viewe implement the pointinside method. When viewd returns true, viewe also triggers this pointinside method. If yes is returned, viewe triggers touch and no is returned. viewd triggers touch. If no is returned in viewd, viewa triggers touch.
Conclusion 1: Calling super hittest is actually to find the event

First, let's talk about the specific configuration. php version: 5.2.5, Apache: 2.2.11, amfphp: 1.9, and Windows XP.
Note: different versions of amfphp may conflict with those of PHP. The specific detection method is: Decompress amfphp in the web root directory and access this URL: http: // localhost/amfphp/Browser/. If no error is reported, congratulations. If any error occurs, replace the amfphp version.
After my test, the configuration above will not be faulty.
Procedure:1. Declare a netconne
Events can appear on the iPhone in three main ways: Action, delegate event, and notification.
The iPhone event response comes from the uiresponder object, while the iPhone notification comes from the nsicationicationcenter. You don't have to worry about how to access the method and attributes of the responder, because the uiresponder object is the parent of most uikit objects, but the nsicationicationcenter requires special access.
I. events and actio
:
The owner of the event: the sender of the message. The host of an event can fire the events it owns under certain conditions, that is, the event is triggered
The responder of the event: the recipient of the message, the processor. Event receivers respond to events using the processor (event Handel) of their events
Subscription relationship for an event: The owner of the event can trigger the event at any time, but will not get a res

You can add a lower line before the first one:Func gcd (_ A:int, B:int), Int {...}In this way, you don't have to modify the original function-that is, you don't need to write the first name. This will simply reduce the amount of code from Swift 2 to Swift 3.[Ecko_alert color= "Gray"] language: to understand the original suggestion of this change,
saves memory. Ten , Talk about the response chainThe first thing to be clear is: IOS , the responder chain responds to the event, and all the response classes are Uiresponder , the responder chain is a hierarchy of different objects, each of which gets an opportunity to respond to an event message in turn. The process of the responder chain:When an event occurs
iOS event mechanism in layman'sApril 12, 2015This article will explain the delivery mechanism of iOS events, such as errors or different views, please note that the message. Reprinted from: http://zhoon.github.io/ios/2015/04/12/ios-event.htmlThere are several types of iOS events: Touch events, motion events (such as gravity and shake), remote events (such as the use of a button on a headset to control your phone), the most common of which is touch Events, which basically exist in each of the app

Problem: Today, I use remoteobject In the flex module to remotely call AMF data with the server. There is no problem when you switch to the module for the first time. However, when you switch to the module for the second time, an error is always reported and remote calls cannot be completed. This is confusing.
During remoting access, I used a custom parameter class:
