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

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.

Pull down the ViewPager of a pig pod and view pager of a pig pod
There is a ViewPager layout in the application details page of pods. A view that can be expanded up or down is added to the layout header to display the application data. Basically, the idea is to use ViewDragHelper to drag to control the layout of the view in the header. When the TopView is visible, the gesture event is intercepted by the dra

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."

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

The Settings dialog box opens as shown below, and then we click on "System Settings" to open the entry
